The developer tools load all of the relevant Maven archetypes for creating integration projects using the Red Hat supported Apache projects.
Add new pieces of logic and functionality to an application.
The developer tools have a wizard for creating Apache Camel context files.
Edit the integration logic.
The developer tools have a visual route editor that makes editing Apache Camel routes as easy as dragging and dropping route components.
Test the application.
The developer tools include testing tools that provide the full gamut of testing capabilities including:
- creating JUnit test cases for Apache Camel routes
- JMX analysis of running components
- message tracing through Apache Camel routes
Deploy the application.
The developer tools can deploy applications to a number of containers.

Chapter 1. Design Time Tooling

1.1. The route editor

Overview

You access the developer tools by opening the Java Perspective, and then selecting File → New → Fuse Project on the menu bar.

Creating a new Fuse project provides access to the route editor, the main design time tooling, shown in Figure 1.1.

Figure 1.1. route editor

It consists of four main areas:

Canvas—the large grid area on which routes are constructed
Palette—the pane to the right of the canvas from which Enterprise Integration Patterns (EIPs) are selected
Project view—the pane on the left side of the canvas, which can display multiple views of the active project. The pane defaults to Package Explorer, which displays the project's folders and files in an hierarchical tree format.
Note
We recommend that you drag Outline view from the upper right side of the workspace to the lower left side, beneath Package Explorer, to provide optimal space for the route editor. Outline view displays, in an outline of EIP icons, the contents of the current <camelContext> element in the routing context file.
Properties editor—the editor in which you configure the selected node's properties. It opens in a tab in the pane below the canvas.

Canvas

The canvas is route editor's workbench and where you do most of your work. It displays a graphical representation of a route, which is made up of one or more connected EIP patterns (called nodes once they are placed on the canvas). Because the canvas displays only one route at a time, it delineates one route from another. You can add additional routes to your project, but each is displayed separately on its own slice of canvas.

Patterns are typically placed on the canvas by dragging them from the palette. Once on the canvas, a node's properties can be edited in the Properties editor. To do so, you need only select a node to open and populate the Properties editor with the properties that apply to that node. You can also edit a route's properties by clicking the canvas, which opens and populates the Properties editor with the properties that correspond to a single route in the routing context file.

Note

Clicking the Source tab at the lower, left of the canvas displays the XML code generated for the route, which you can then edit. The edits you make in Source view appear on the canvas when you switch back to Design View.

Palette

The Palette contains all of the patterns needed to construct a route. The Palette groups the patterns into categories according to function:

Endpoints—patterns that start or end a route
Routing—patterns that direct the flow of messages based on specified criteria
Control Flow—patterns that behave like control functions in a programming language. For example, some define loops, some handle error conditions, some handle transactions, and so on.
Transformation—patterns that change the contents of a message as it passes through a route
Miscellaneous—patterns that control the environment in which a route executes. For example, the Threads pattern specifies the number of threads available.

Package Explorer

Package Explorer provides access to all of the components that make up a project. It provides the tools for managing, configuring, running, and debugging your project.

Outline view

Outline view provides a graphical outline of your route components. It enables you to switch easily between routes in a multiroute project. Clicking on a route in Outline view displays it on the route editor's canvas.

Outline view also provides a viewing portal when the route extends beyond the viewable area on the canvas. Sliding the view portal in Outline view over outlier nodes moves the canvas accordingly to bring those nodes into view.

Properties editor

You use the Properties editor to configure the route and each node in it. Each type of node has a set of properties that can or must be set. The Properties editor opens populated with fields that apply to the selected node.

The Properties editor makes it clear which fields are required.

marks any required property that is not set, and the Properties editor displays an error message stating the number of required properties that still must be set, as shown in Figure 1.2.

Figure 1.2. Properties editor's error reporting

The Properties editor's Documentation tab displays information about how to configure the selected node.

1.2. Creating projects, routes, and test cases

Overview

While you'll spend the majority of your time using the route editor, the developer tools include wizards that facilitate creating the following:

Red Hat JBoss Fuse projects
Apache Camel context files
Apache Camel-specific JUnit tests

Fuse projects

The developer tools leverage the m2e plug-in's ability to execute Maven archetypes to create starting point projects for working on Apache Camel routes. The New Fuse Project wizard displays the Apache Camel Maven archetype options. Selecting one creates a project that is properly configured for developing Apache Camel applications.

For more information, see Chapter 2, Creating a New Fuse Project.

Apache Camel context files

Apache Camel context files are the key piece of any project. They contain the routing rules that form the backbone of an Apache Camel application. The developer tools have a simple wizard that creates new Apache Camel context files.

For more information, see Chapter 3, Creating a New Camel XML file.

Apache Camel test cases

The developer tools provide a wizard that generates JUnit code for testing your routes. The wizard makes it easy to select the assertions to test. It also simplifies the process of testing particular endpoints in a route.

For more information, see Chapter 5, Creating a new Apache Camel JUnit test case.

Fuse messages

The developer tools provide a wizard that creates a message that you can use to test a route. You drop the message on Camel endpoints or ActiveMQ destinations to track its progress through the route. The wizard creates a skeletal message, which you can edit to customize the content of both the message body and the message header.

For more information, see Section 14.1, “Creating test messages for route tracing”.

1.3. Exercising routes

Revision History

	09/09/12	EMJ
removed subscription restriction comments

Overview

In addition to simplifying the process of creating and editing routes, the developer tools provide tools to make it easier to run your routes and deploy them into test environments. Using the developer tools you can:

run a route using Maven
run a route as a local Apache Camel context
deploy into a running OSGi container

Using Maven

You can run your route with Maven, using Maven's standard goals. This method closely simulates how an Apache Camel project would run outside of the developer tools.

See Section 7.3, “Working with runtime profiles”.

Running as a local Apache Camel context

You can run all routes in a context directly inside the developer tools without setting up a Maven runtime profile. You can run routes locally with or without running validation tests. Running a context directly inside the developer tools does not require that your project be a Maven project.

Deploying to OSGi

You can also deploy routes into a running OSGi container. The developer tools support deployment into these OSGi containers: Red Hat JBoss Fuse v6.x, Apache ServiceMix v4.x, and Apache Karaf v2.x.

See Chapter 8, Deploying Projects to a Container.

Overview

The developer tools use Maven archetypes to generate a project with all of the dependencies preconfigured. The archetypes also create the POM file needed to run and deploy your application, as well as sample code and data to get you started.

Procedure

To create a Fuse project:

Select File → New → Fuse Project to open the New Fuse Project wizard shown in Figure 2.1, “New Fuse Project Wizard's Project Location Page”.
Figure 2.1. New Fuse Project Wizard's Project Location Page
The wizard opens with the Use default workspace location option selected on the location page.
Specify the location where the data for the project will be stored.
- To use the default workspace select Use default workspace location.
- To use an alternative location deselect Use default workspace location and specify a new location in the provided field.
  Clicking opens a file browser.
If you want to add the new project to an Eclipse working set, select Add project(s) to working set and enter the name of the working set.
Click to open the New Fuse Project details page shown in Figure 2.2.
Figure 2.2. New Fuse Project wizard's details page
Select a project type from the list.
Note
The route editor works with these project types:
- camel-archetype-activemq
  Creates a new Apache Camel project that configures and interacts with Apache ActiveMQ.
- camel-archetype-blueprint
  Creates a new Apache Camel project with support for OSGi blueprint.
- camel-archetype-component
  Creates a new Apache Camel project for building a new component.
- camel-archetype-component-scala
  Creates a new Apache Camel project for building a new component using Scala.
- camel-archetype-dataformat
  Creates a new Apache Camel project for building a new data format.
- camel-archetype-java
  Creates a new Apache Camel project using Java DSL.
  You cannot edit Java DSL in the route editor.
- camel-archetype-scala
  Creates a new Apache Camel project using Scala DSL.
- camel-archetype-spring
  Creates a new Apache Camel project with added support for Spring DSL.
- camel-archetype-spring-dm
  Creates a new Apache Camel web project that deploys the routes as a WAR.
- camel-archetype-web
  Creates a new Apache Camel project with added support for Spring DSL.
- camel-archetype-webconsole
  Creates a new Apache Camel project that deploys the Apache Camel Web Console, REST API, and your routes as a WAR.
- camel-cxf-code-first-archetype
  Creates a new Apache Camel project using Apache CXF code (Java) first.
- camel-cxf-contract-first-archetype
  Creates a new Apache Camel project using Apache CXF contract (WSDL) first.
- camel-drools-archetype
  Creates a new Apache Camel project that uses the Drools rule engine. Because this archetype is not yet OSGi ready with Spring and Camel, it is provided as a technical preview only. It is not ready for use in production environments.
Enter a group ID for the project in the Group Id field, or accept the default.
The developer tools use the group ID to form the first part of the dot-separated package name. For example, if you enter Demo for the group ID, it appears in the Package field as Demo..
Enter an artifact ID for the project in the Artifact Id field, or accept the default.
The developer tools use the artifact ID as the name of the project and to form the second part of the dot-separated package name. For example, if you enter BigRoute for the artifact ID, it appears in the Package field as Demo.BigRoute.
Enter a version for the project in the Version field, or accept the default.
If you want to change the package name generated for the artifacts, enter the new package name in the Package field.
Click Finish to create the Maven project, which contains starting point artifacts.

Resolving Maven dependency errors

You may encounter Maven dependency errors after you create a new Fuse project.

Though it can happen at other times, it more typically occurs when you create a project based on any of the supplied archetypes for the first time, but then cancel the project before the process finishes. Interrupting the process in this way often prevents all of the project's dependencies from downloading from the Maven repositories, which can take some time.

You can often easily resolve these dependency errors by updating Maven dependencies this way:

In Package Explorer, select the root project just created.
Right-click it to open the context menu.
Select Maven → Update Project...
In the Update Maven Project wizard, check Force Update of Snapshots/Releases.
Click OK.
In the bottom, right corner of the workbench, you may see the progress status bar churning as missing dependencies are downloaded from the Maven repositories.

Overview

Apache Camel stores routes in an XML file that contains a camelContext element. The developer tools include a wizard that simplifies adding an Apache Camel context file to your project. It creates a new XML file that has all of the required namespaces preconfigured and a template camelContext element.

Procedure

To add an Apache Camel context file to your project:

Select File → New → Camel XML File from the main menu to open the Camel XML File wizard, as shown in Figure 3.1, “Camel XML File wizard”.
Figure 3.1. Camel XML File wizard
In RouteContainer, enter the location for the new file, or accept the default.
You can click to search for an appropriate location.
Important
The Spring framework and the OSGi Blueprint framework require that all Apache Camel files be placed in specific locations under the project's META-INF folder:
- Spring—projectName /src/main/resources/META-INF/spring/
- OSGi Blueprint—projectName /src/main/resources/META-INF/blueprint/
In File Name, enter a name for the new context file, or accept the default.
The file's name cannot contain spaces or special characters, and it must be unique within the JVM.
In Framework, accept the default, or select which framework the routes will use:
- Spring—for routes that will be deployed in Spring containers, non-OSGi containers, or as standalone applications
- OSGi Blueprint—for routes that will be deployed in OSGi containers
- Routes—for routes that you can load and add into existing camelContexts
Click Finish.
The new context file is added to the project and opened in the route editor.

Chapter 4. Editing a routing context in the route editor

Revision History
	8/11/11	EMJ
Added editor configuration topic

Developing an Apache Camel application typically consists of the following tasks:

Adding one or more routes to the routing context.
Adding a starting point pattern to a route.
Adding one or more endpoint patterns to a route.
Adding one or more processor patterns that represent how messages will be transformed and routed between the starting point and endpoint(s).
Connecting the patterns (referred to as nodes once they are placed on the canvas).
Configuring the details for each of the endpoints and processors that make up the route.
Adding any configuration beans to the context.

4.1. Adding routes to the routing context

Overview

The camelContext element within an xml context file creates a routing context. The camelContext element can contain one or more routes, but the route editor's canvas can display only one of the routes at a time. Therefore the canvas is each route's delineator, and each route displayed on the canvas maps to a route element in the generated camelContext element.

When you create a new Fuse Project, the developer tools create a camelContext.xml file that contains an empty route element within a camelContext element. You can view and edit the contents of the camelContext.xml file in the route editor's Source view. In Design view, the route editor presents an empty canvas, which represents the empty route element. You can drag patterns from the Palette and drop them onto the canvas to create a route. The design time tooling updates the empty route element with xml generated from the patterns you drop onto the canvas.

The developer tools provide three methods for adding a new route:

From the menu bar, by opening the Routes menu, and then selecting Add Route
In Design view, by right-clicking the canvas or a node to access the context menu, and then selecting Add → Route
In Source view, by adding a <route/> element to the existing list within the camelContext element

Procedure

To add another route to the camelContext:

Select one of the methods for adding a route.
In Design view, a route icon appears in Outline view, and the Properties editor displays the list of the new route's properties for you to edit.
In the Properties editor, enter an ID (for example, Route2) for the new route in the route's ID field.
In Outline view, the new ID displays next to the new route icon.
In the Properties editor, enter a description of the route in the Description field.
On the menu bar, select File → Save to save the changes you made to the routing context file.

Note

To switch between multiple routes, select the route you want to display on the canvas by clicking it in Outline view or by selecting it from the Routes menu on the menu bar.

4.2. Adding patterns to a route

Routes consist of a sequence of connected patterns, referred to as nodes once they are placed on the canvas. To add a pattern to a route you can either:

Drag the pattern from the palette
Use the context menu

Both methods provide access to all of the available patterns. Dragging patterns from the palette and dropping them onto the canvas is an easy and convenient way to add multiple patterns to the canvas quickly. Using a node's context menu, you can add and automatically connect a pattern to the node.

4.2.1. Drag and drop a pattern

Overview

The Palette lists all of the available patterns, grouped by function. For example, the Loop pattern is part of the Control Flow group.

You can select any pattern from the Palette and drag it to the canvas, which represents a single route.

Procedure

To drag a pattern onto a route:

In the Palette, locate the desired pattern.
Select the pattern, drag it to the canvas, and then release the mouse button.
Note
You need not place the pattern in its intended location. You can easily move any node on the canvas by dragging it to a new location.

The new pattern appears on the canvas and becomes the selected node. The Properties editor displays a list of the node's properties for you to edit and configure.

4.2.2. Using the context menu

Overview

Nodes on the canvas have a context menu that includes an Add option for adding new patterns to a route.

Procedure

To add and connect a pattern to a node in a route:

In the canvas, select the node to which you want to connect the new pattern.
Right-click it to open the context menu.
Select Add to display the list of patterns that can be connected to the selected node. The patterns are grouped according to function.
Select the pattern to add to the route.

The new pattern is added to the route and automatically linked to the selected node. The new pattern becomes the currently selected node, and the Properties editor displays a list of the node's properties for you to edit and configure.

4.3. Connecting patterns to make a route

Overview

Until the patterns on the canvas (referred to as nodes) are connected, they do not constitute a route. The editor does not save a route element in the context file until all nodes are linked together to form a complete route. A complete route typically consists of a starting endpoint, a string of processing nodes, and one or more destination endpoints.

Connecting two nodes on the canvas is as simple as dragging a line from one to the other. Each node has a connector arrow. Selecting a node and dragging its connector arrow to a target node establishes a connection between the two nodes.

Procedure

To connect two nodes:

On the canvas, select the source node to display its connector arrow.
Click-drag the source node's connector arrow ( ) to the target node.
The direction of the connection represents the direction messages flow between the nodes in the route.
While hovering over the target node, release the mouse button to drop the connector on it.
The route editor updates the <route> element with the xml generated from the connection. You can view the xml in Source view.
When you are done, save your work by selecting File → Save from the menu bar.

4.4. Configuring a pattern

Overview

Most patterns require some explicit configuration. For example, an endpoint requires an explicitly entered URI.

The developer tools' Properties editor provides a form that lists all of the configuration details a particular pattern supports. The Properties editor also provides the following convenience features:

validating that all required properties have values
drop-down lists for properties that have a fixed set of values
drop-down lists that are populated with the available bean references from the Apache Camel Spring configuration

Procedure

To configure a pattern:

On the canvas, select the node you want to configure.
The Details tab in the Properties editor lists all of the selected node's properties for you to edit. The Documentation tab describes the pattern and each of its properties.
Edit the fields in the Properties editor to configure the node.
When done, save your work by selecting File → Save from the menu bar.

4.5. Rearranging patterns on the canvas

As your route grows and changes, you'll likely need to change how it is laid out on the canvas. Changing the layout does not change the underlying DSL, but it does make it easier to visualize the route.

The developer tools provide two ways to rearrange the patterns on the canvas:

dragging and dropping
the context menu's

4.5.1. Rearranging patterns by dragging them

Overview

You can select one or more nodes on the canvas and drag them to a new location. Each node's connections are retained and move along with it. However, the layout of the route will continue to change as it grows in scope and complexity.

Procedure

To drag a node to a new location on the canvas:

Determine which node or nodes you want to move.
Select one node, or select a group of nodes by dragging a box around them.
Drag the node or nodes to their new location, then release the mouse button.

Note

You can also rearrange the connectors between nodes to accommodate increasing numbers of patterns on the canvas. Clicking a connector joining two nodes on the canvas reveals a line segmented by a bendpoint. You can drag the bendpoint to another location on the canvas while leaving the two nodes in place. Dragging a bendpoint creates two new bendpoints on either side of it, further segmenting the connector. This feature makes it easy to organize the nodes in a complex route for visual clarity.

4.5.2. Automatically aligning patterns

Overview

The Layout Diagram command on the canvas' context menu automatically aligns all nodes on the canvas relative to the route's start point. By default, the route editor arranges the nodes in a route from left to right across the canvas, according to the order in which they are connected to each other. It moves the start point to the left edge of the canvas, then aligns the processing nodes and endpoints accordingly.

Note

You can change the default layout direction (Right). To do so, on the menu bar select JBoss Developer Studio → Preferences → Fuse Plugins for Eclipse → Editor, and then select Down from the Choose the layout direction for the diagram editor's drop-down list

You can continue adding more patterns to your route after you execute the Layout Diagram command.

Procedure

To direct the developer tools to automatically align all nodes on the canvas:

Right-click the canvas to open the context menu.
Select Layout Diagram.

4.6. Removing patterns from a route

Overview

As you develop and update a route, you may need to remove one or more of the route's nodes. The Remove option on the nodes' context menu makes this easy to do. When you delete a node from the canvas, all of its connections with all other nodes on the canvas are also deleted.

Note

You can also remove a node by right-clicking it in Outline view and selecting Remove, or by selecting Edit → Delete from the menu bar.

Procedure

To remove a node from a route:

Select the node you want to delete.
Right-click it to open the context menu.
Select Remove.

The node and all of its connections are deleted from the canvas.

4.7. Disconnecting two patterns

Overview

As you develop and update a route, you may need to disconnect some nodes. The Remove option on the connector context menu makes this easy to do.

Note

You can also delete a connector by selecting Edit → Delete from the menu bar.

Procedure

To disconnect two nodes:

Select the connector you want to delete.
Right-click it to open the context menu.
Select Remove.

The connector between the nodes is removed.

4.8. Deleting a route

Overview

In some cases you made need to delete an entire route from your routing context. The Remove Route option on the canvas' context menu makes this easy to do. When you delete a route, all of the nodes the route contains are also deleted.

Note

You can also remove a route from the Routes menu on the menu bar.

Procedure

To delete a route:

If the routing context contains more than one route, first select the route you want to delete in Outline view.
Right-click on the canvas to open the context menu.
Select Remove Route.

The route is removed from the canvas and from the camelContext.

4.9. Adding beans and configuration

Revision History
	7/22/11	EMJ
added link to source editor topic and changed Spring Beans to beans

Overview

Many routing patterns rely on references to Java objects (beans) for configuration or for implementation details. You add the beans into the routing context file using the route editor's Source tab.

Procedure

To add beans to your routing context file:

Open your routing context file in the route editor.
Click the Source tab at the bottom of the route editor's canvas to switch to Source view, so you can edit the XML that defines the route.
Enter the bean elements needed by your route before the camelContext element.
Note
Use the id attribute to identify the bean, not the name attribute.
Important
Do not edit the contents of the camelContext element. Red Hat JBoss Fuse Plugins for Eclipse overwrites the camelContext element when changes are made to the route diagram in Design view.
Save your changes by selecting File → Save on the menu bar.
Click the Design tab at the bottom of the route editor's canvas to return to Design view and the route diagram.

4.10. Configuring the route editor

Overview

Using the JBoss Developer Studio's preference panel, you can specify many aspects of the route editor's behavior:

The default language to use for expressions in EIPs
The method for labeling nodes on the canvas
The direction in which patterns flow on the canvas when creating routes
Whether the canvas displays a grid overlay
Colors used for various diagrammatic components

Procedure

To configure the route editor:

On the menu bar, select JBoss Developer Studio → Preferences to open the Preferences dialog.
Select Fuse Plugins for Eclipse → Editor to show the Editor Preferences.
Select the expression language you prefer from the drop-down list.
Click the checkbox next to If enabled the ID values will be use for labels if existing to enable or disable using node IDs as labels.
Select, from the drop-down list, the direction in which you want the route editor to align the patterns in a route.
Click the checkbox next to Show diagram grid to enable or disable displaying the grid overlay on the canvas.
Click Apply to apply the changes to the Editor Preferences.
Select Fuse Plugins for Eclipse → Colors to show the Colors Preferences.
For each component whose color you want to change, click its color icon to open the color palette, and then select a color from the palette.
When done, click Apply and then OK, to close the Preferences dialog.
You can restore the route editor's original color scheme at any time by returning to Fuse Plugins for Eclipse → Colors and clicking Restore Defaults.

Chapter 5. Creating a new Apache Camel JUnit test case

Revision History
	11/16/2012	JCM
Added heads up for users to edit their JUnit test case to ensure it runs a valid test

Overview

A common way of testing routes is to use JUnit. The design time tooling includes a wizard that simplifies creating a JUnit test case for your routes. The wizard uses the endpoints you specify to generate the starting point code and configuration for the test.

Note

After you create the boilerplate JUnit test case, you need to modify it to add expectations and assertions specific to the route that you've created or modified, so the test is valid for the route.

Procedure

To create a new JUnit test case for your route:

In Package Explorer, select the camel-context.xml file in your routing project.
Right-click it to open the context menu, and then select New → Camel Test Case to open the New Camel JUnit Test Case wizard, as shown in Figure 5.1, “New Camel JUnit Test Case wizard”.
Figure 5.1. New Camel JUnit Test Case wizard
Alternatively, you can open the wizard by selecting File → New → Camel Test Case from the menu bar.
In Source folder, accept the default location of the source code for the test case, or enter another location.
You can click to search for a location.
In Package, accept the default package name for the generated test code, or enter another package name.
You can click to search for a package.
In Camel XML file under test, accept the default pathname of the routing context file that contains the route you want to test, or enter another pathname.
You can click to search for a context file.
In Name, accept the default name for the generated test class, or enter another name.
Select the method stubs you want to include in the generated code.
If you want to include the default generated comments in the generated code, check the Generate comments box.
Click to open the Test Endpoints page. For example, Figure 5.2, “New Camel JUnit Test Case page” shows a route's input and output file endpoints selected.
Figure 5.2. New Camel JUnit Test Case page
Under Available endpoints, select the endpoints you want to test. Click the checkbox next to any selected endpoint to deselect it.
Click .
Note
If prompted, add JUnit to the build path.

The artifacts for the test are added to your project and appear in Package Explorer under src/test/java. The class implementing the test case opens in the Java editor.

Chapter 6. The Source View

The developer tools' Source tab opens the route editor in Source view (Figure 6.1) to display the contents of an Apache Camel route file as XML.

Figure 6.1. Source view

This view is useful for editing and adding any configuration, comments, or beans to the routing context file. The Properties editor can inspect the beans and use the information to populate the fields that require bean references.

While the route editor allows you to change the contents of the camelContext element in the routing context file, not all changes are preserved. Comments inserted into the camelContext element are lost upon switching to Design view.

Chapter 7. Running routes inside Red Hat JBoss Fuse Plugins for Eclipse

There are two basic ways to run your routes using the developer tools:

As a local camel context (with or without tests)
Using Maven

7.1. Running routes using Maven

Overview

If the project containing your route is a Maven project, you can use the m2e plug-in to run your route. Using this option, you can execute any Maven goals, before the route runs.

Procedure

To run a route using Maven:

In Package Explorer, select the root of the project .
Right-click it to open the context menu, and then select Run As → Maven build.
- The first time you run the project using Maven the Edit Configuration editor opens, so you can create a Maven runtime profile.
  To create the runtime profile:
  1. Make sure the route directory of your Apache Camel project appears in the Base directory: field.
    For example on Linux the root of your project will be similar to ~/workspace/simple-router.
  2. In the Goals: field, enter camel:run.
  3. Click Apply and then Run.
- Subsequent Maven runs use this profile, unless you modify it between runs.

Results

The Console view displays the output from the Maven run.

7.2. Running routes as a local Camel context

Overview

The simplest way to run an Apache Camel route is as a Local Camel Context. This method enables you to launch the route directly from Package Explorer's context menu. When you run a route from the context menu, the developer tools automatically create a runtime profile for you. You can also create a custom runtime profile for running your route.

Your route runs as if it were invoked directly from the command line and uses Apache Camel's embedded Spring container. You can configure a number of the runtime parameters by editing the runtime profile.

Procedure

To run a route as a local Camel context:

In Package Explorer, select a routing context file.
Right-click it to open the context menu, and then select Run As → Local Camel Context.
Note
Selecting Local Camel Context (without tests) directs the Red Hat JBoss Fuse Plugins for Eclipse to run the project without performing validation tests, which may be faster.

Result

The Console view displays the output generated from running the route.

7.3. Working with runtime profiles

The Red Hat JBoss Fuse Plugins for Eclipse store information about the runtime environments for each project in runtime profiles. The runtime profiles keep track of such information as which Maven goals to call, the Java runtime environment to use, any system variables that need to be set, and so on. A project can have more than one runtime profile.

7.3.1. Editing a Local Camel Context runtime profile

Overview

A Local Camel Context runtime profile configures how Apache Camel is invoked to execute a route. A Local Camel Context runtime profile stores the name of the context file in which your routes are defined, the name of the main to invoke, the command line options passed into the JVM, the JRE to use, the classpath to use, any environment variables that need to be set, and a few other pieces of information.

The runtime configuration editor for a Local Camel Context runtime profile contains the following tabs:

Camel Context File—specifies the name of the new configuration and the full path of the routing context file that contains your routes.
Main—specifies the fully qualified name of the project's base directory, a few options for locating the base directory, any goals required to execute before running the route, and the version of the Maven runtime to use.
JRE—specifies the JRE and command line arguments to use when starting the JVM.
Refresh—specifies how Maven refreshes the project's resource files after a run terminates.
Environment—specifies any environment variables that need to be set.
Common—specifies how the profile is stored and the output displayed.

The first time an Apache Camel route is run as a Local Camel Context, Red Hat JBoss Fuse Plugins for Eclipse creates for the routing context file a default runtime profile, which should not require editing.

Accessing the Local Camel Context's runtime configuration editor

In Package Explorer, select the camelContext file for which you want to edit or create a custom runtime profile.
Right-click it to open the context menu, and then select Run As... → Run Configurations to open the Run Configurations dialog.
In the context selection pane, select Local Camel Context, and then click at the top, left of the context selection pane.
In the Name field, enter a new name for your runtime profile.

Figure 7.1. Runtime configuration editor for Local Camel Context

Local camel context runtime configuration editor

Setting the camel context file

The Camel Context File tab has one field, Select Camel Context file.... Enter the full path to the routing context file that contains your route definitions.

The Browse... button accesses the Open Resource dialog, which facilitates locating the target routing context file. This dialog is preconfigured to search for files that contain Apache Camel routes.

Changing the command line options

By default the only command line option passed to the JVM is:

-fa context-file

If you are using a custom main class you may need to pass in different options. To do so, on the Main tab, click the Add button to enter a parameter's name and value. You can click the Add Parameter dialog's Variables... button to display a list of variables that you can select.

To add or modify JVM-specific arguments, edit the VM arguments field on the JRE tab.

Changing where output is sent

By default, the output generated from running the route is sent to the Console view. But you can redirect it to a file instead.

To redirect output to a file:

Select the Common tab.
Click the checkbox next to the File: field, and then enter the path to the file where you want to send the output.
The Workspace..., File System..., and Variables... buttons facilitate building the path to the output file.

7.3.2. Editing a Maven runtime profile

Overview

A Maven runtime profile configures how Maven invokes Apache Camel. A Maven runtime profile stores the Maven goals to execute, any Maven profiles to use, the version of Maven to use, the JRE to use, the classpath to use, any environment variables that need to be set, and a few other pieces of information.

The runtime configuration editor for a Fuse runtime profile contains the following tabs:

Main—specifies the name of the new configuration, the fully qualified name of the project's base directory, a few options for locating the base directory, any goals required to execute before running the route, and the version of the Maven runtime to use.
JRE—specifies the JRE and command line arguments to use when starting the JVM.
Refresh—specifies how Maven refreshes the project's resource files after a run terminates.
Environment—specifies any environment variables that need to be set.
Common—specifies how the profile is stored and the output displayed.

The first time an Apache Camel route is run using Maven, you must create a default runtime profile for it.

Accessing the Maven runtime configuration editor

In Package Explorer, select the root of the project for which you want to edit or create a custom runtime profile.
Right-click it to open the context menu, and then select Run As... → Run Configurations to open the Run Configurations dialog.
In the context selection pane, select m2 Maven Build, and then click at the top, left of the context selection pane.

Figure 7.2. Runtime configuration editor for Maven

Changing the Maven goal

The most commonly used goal when running a route is camel:run. It loads the routes into a Spring container running in its own JVM.

The Apache Camel plug-in also supports a camel:embedded goal that loads the Spring container into the same JVM used by Maven. The advantage of this is that the routes should bootstrap faster.

If your POM contains other goals, you can change the Maven goal used by clicking the Configure... button next to the Maven Runtime field on the Main tab. On the Installations dialog, you edit the Global settings for <selected_runtime> installation field.

Changing the version of Maven

By default, the Red Hat JBoss Fuse developer tools use m2e, which is embedded in Eclipse. If you want to use a different version of Maven or have a newer version installed on your development machine, you can select it by editing the Maven Runtime field on the Main tab.

Changing where the output is sent

By default, the output from the route execution is sent to the Console view. But you can redirect it to a file instead.

To redirect output to a file:

Select the Common tab.
Click the checkbox next to the File: field, and then enter the path to the file where you want to send the output.
The Workspace..., File System..., and Variables... buttons facilitate building the path to the output file.

Chapter 8. Deploying Projects to a Container

Revision History
	8/11/11	EMJ
made a chapter with sections to include container config
	7/13/12	EMJ
rewrote for clarity and accuracy
	7/13/12	EMJ
merged configuration of hot deploy folder and hot deploy procedure into a single section

The developer tools' Deploy to... tool(

) makes deploying applications into containers a one step process.

The developer tools support direct deployment into the following containers:

Red Hat JBoss Fuse
Apache ServiceMix
Apache Karaf

There are three ways to deploy Fuse projects into a container:

into a container's deploy folder
You copy the package generated by the developer tools into the container's deploy folder. This method has two drawbacks:
- The developer tools do not verify that the project builds a package that is compatible with the target container.
- The developer tools do not provide feedback as to whether the deployment succeeds or fails.
to a JMX connected container
The developer tools build the project, and, regardless of the packaging specified in the project's POM, installs the generated artifacts as a bundle. You can use the Fuse JMX Navigator to determine if the project deploys successfully.
to a fabric profile
The developer tools build the project, packages the generated artifacts into a bundle, adds the bundle to the profile, and copies the bundle into the fabric's internal repository.
Important
If the profile is not assigned to a running container the project will not be deployed into the fabric. You must assign the profile to a running container before you can see the project running.

Note

You can deploy a project by dropping it onto a connected container in Fuse JMX Navigator, or onto a fabric profile in Fabric Navigator.

8.1. Using a Container's Deploy Folder

When the developer tools deploy a project into a container's deploy folder, they build the project as specified in the project's POM and copies the resulting package to a predetermined location. The developer tools assume two things:

the specified location is a container's deploy folder
the package generated by the project is compatible with the container

Before you can deploy a project to a container's deploy folder you must add the container's deployment information to the developer tools. Once the developer tools know the container's information, the container will appear as an option in the Deploy To... menu.

8.1.1. Configuring a Container's Deploy Folder

Revision History
	7/22/11	EMJ
Added info about opening the container preferences
	7/13/12	EMJ
changed deployment folder to deploy folder so it is consistent with the UI
	7/13/12	EMJ
edited for clarity

Overview

Before you can deploy applications into a container's deploy folder, you must provide the developer tools with the location of the container's deploy folder. The Deploy Folders preference panel enables you to configure one or more containers. You provide a name for the container and the full path to the container's deployment folder.

Accessing the Deploy Folder preference panel

You can access the deployment folders preference panel two ways:

selecting JBoss Developer Studio → Preferences → Fuse Plugins for Eclipse from the main menu
This method opens the general Eclipse preference window. You need to select Deploy Folders from the list of preferences in the panel on the left side of the widow.
selecting Deploy to... → Deploy Folder Configurations... from the project's context menu
This method opens the preferences window and ensures that the Deploy Folders panel is selected.

Add a container's deploy folder

To add a container's deploy folder:

Open the Deploy Folder preference panel.
In the Name field, enter a name for the target container.
The name can be any unique string.
In the Deploy Folder field, enter the full path to the container's deployment folder.
The button opens a file explorer.
Important
The developer tools do not validate whether the selected folder is a valid deployment folder for a container.
In the Description field, enter a description for the container.
Click Add to add the new container to the table of configured containers.
Click OK to close the preferences window.

When add a container to the list, it appears in the context menus'

Deploy to... submenu.

Edit a container's deploy folder

To edit a container's deploy folder:

Open the Deploy Folder preference panel.
Select the container whose configuration you want to edit.
Edit the information that needs updating.
Important
Changing the value of the Name field creates a new container configuration.
Click .
Click OK to close the preferences window.

Delete a container's deploy folder

To delete a container's deploy folder:

Open the Deploy Folder preference panel.
Select the container to be deleted.
Click .
Click OK to close the preferences window.

8.1.2. Deploying a Project to a Container's Deploy Folder

Revision History
	8/11/11	EMJ
Split into a section

Overview

When the developer tools deploy a project to a container's deploy folder it builds the project and copies the results to the deploy folder configured for the container.

Procedure

To deploy a project to a container's deploy folder:

Select the routing context file that you want to deploy.
Important
The project must be configured to package the results in a format that the target container can deploy.
Select Deploy to... → containerName from the project's context menu.
Red Hat JBoss Fuse Plugins for Eclipse builds the project and copies the results to the selected container's deploy folder.
Note
If you have not already configured a container, you can do so by selecting Deploy to... → Deploy Folder Configurations... from the context menu.
See Section 8.1.1, “Configuring a Container's Deploy Folder”.
Check the Console view to see if your project was successfully built and copied to the target container.
Check the container's log files to see if the project was successfully deployed.

8.2. Deploying a Project to a JMX Connected Container

Overview

Deploying into a container connected to the developer tools' Fuse JMX Navigator provides a number of benefits over using a container's deploy folder. The chief benefits are that the project is automatically packaged into a bundle, and you can monitor the results of the deployment in the developer tools.

All of the supported containers that are connected to the Fuse JMX Navigator are listed in the Deploy to... menu. For information about how to connect a container to the Fuse JMX Navigator, see Chapter 11, The Fuse JMX Navigator.

Procedure

To deploy a project to a JMX connected container:

Open the Fuse Integration perspective.
In Fuse JMX Navigator, expand the JMX server hosting the desired container.
Containers that are running on the local machine are listed in the special Local Processes node.
Double-click the entry for the desired container connect to it.
In Project Explorer, select the project you want to deploy.
Open the project's context menu.
Click Deploy to... → container[xxx].
Check the Console view to see that your project builds successfully and is installed in the container.
In Fuse JMX Navigator, click container[xxx] → Bundles to populate the Properties view with the list of bundles installed in the container.
Use the search tool in Properties view to check that your project's bundle was installed.
When you start typing the name of your project the search tool will display the bundles whose names match the current string.
In Fuse JMX Navigator, open container[xxx]'s context menu.
Click Refresh.
Expand the container[xxx] node to view your project's nodes.
Now you can test and debug your application in a Red Hat JBoss Fuse environment.

8.3. Deploying a Project to a Fabric Container

Revision History
	7/19/12	EMJ
rewrote for clarity and accuracy

Overview

When you are ready to test your application in a highly distributed environment, you can deploy it into a fabric using the Deploy to... tool. The Deploy to... tool builds your application, runs the tests, packages the application as a bundle, adds the bundle to a fabric profiles, and deploys the bundle into the fabric's internal Maven repository.

To complete the process, you need to ensure that the profile containing your application is deployed to at least one of the containers in the fabric. If the profile is not deployed to a container, the application will not be started.

Procedure

To deploy a project to a fabric container:

Open the Fuse Integration perspective.
In Fabric Navigator, expand the Fabrics node.
Double-click a fabric to connect to it.
Create a new profile in which you will install your project.
Follow the steps in Section 24.1, “Creating a new profile” up to Step 6.
The new profile appears in the profile tree in Fabric Navigator.
In Project Explorer, select the project you want to deploy.
Open the project's context menu.
Select Deploy to... → fabric → version to see the list of available profiles.
From the list of profiles, select the profile that you created in Step 4.
Verify that the application's bundle was added to the profile.
1. In Fabric Navigator, click the profile into which the project was installed.
  This will populate the Properties view with the profile's details.
2. In Properties view, click the Details tab.
3. Check that your project's bundle appears in the Bundles or FABs field.
If you do not already have a container deployed into the fabric for testing your application, create a new container in the fabric.
Follow the procedure appropriate for the container in Chapter 23, Working with Fabric Containers.
The new container appears in Fabric Navigator, under the fabric's Containers node.
Assign the profile containing your application to a container in the fabric.
Follow the procedure in Section 23.5, “Changing a Container's Profiles”.
Verify that the application was deployed to the container.
1. In Fabric Navigator, double-click the new container to start it and to populate Properties view with its properties and profile information.
2. In Fabric Navigator, click the container's Bundles node to view the list of bundles installed on it.

Chapter 9. Debugging tooling

9.1. The Fuse Integration perspective

Overview

The Fuse Integration perspective, shown in Figure 9.1, is where you do most of your debugging.

Figure 9.1. Fuse Integration perspective

The Fuse Integration perspective consists of five main areas:

Fuse JMX Navigator—lists the JMX servers and the infrastructure they monitor.
Diagram View—provides a graphical representation of an item selected in the Fuse JMX Navigator. If the selected item is a route, Diagram view also displays timing metrics for each processing step in the route.
Messages View—lists the messages that have passed through the selected JMS destination or Apache Camel endpoint.
Servers—lists the Red Hat JBoss Fuse, Apache Karaf, or Apache ServiceMix containers defined in the debugging tooling environment.
Properties—displays the properties of the selected item.

Fuse JMX Navigator

The Fuse JMX Navigator drives the debugging activities in the Fuse Integration perspective. It determines which routes are displayed in the Diagram View, the Properties viewer, and the Messages View. It is also provides menu commands for activating route tracing, adding and deleting JMS destinations, and starting and stopping routes. It is also the target for dragging and dropping messages onto a route.

By default, the Fuse JMX Navigator shows all of the Java processes running on your local machine. You can add JMX servers as needed to view infrastructure on other machines.

Messages view

The Messages View is used for JMS browsing and route tracing.

When a JMS destination is selected in the Fuse JMX Navigator, the view lists all of the messages sitting in the destination.

When a browsable Apache Camel endpoint is selected and route tracing has been activated, the view lists all of the messages that have passed through the endpoint since tracing was activated.

When a message in the Messages View is selected, its details are displayed in the Properties viewer. The message details include the message's body and all of its headers.

9.2. Infrastructure monitoring

Overview

A large portion of the Fuse Integration perspective is dedicated to visualizing the processes running in your infrastructure. In addition to displaying the running processes, the Fuse Integration perspective also displays all of the runtime metrics that are gathered from JMX MBeans.

Visualizations

The Fuse JMX Navigator and the Diagram View show you the processes deployed as part of your integration infrastructure.

The Fuse JMX Navigator arranges items in a tree and drives the rest of the operations on the Fuse Integration perspective.

Diagram View shows your infrastructure as a graph. It shows all of the nodes under the item selected in Fuse JMX Navigator.

For more information see Chapter 11, The Fuse JMX Navigator.

JMX metrics

JMX metrics are displayed in the Properties view of the Fuse Integration perspective. Depending on the type of process, the JMX metrics provide details such as:

time running
time to process a message
number of messages processed
processor load
memory foot print

For more information see Chapter 12, Viewing a component's properties.

9.3. Route debugging

Overview

When debugging a route, it is helpful to see how a test message changes as it passes through the route. It is also helpful to trace the message's path through the route.

The developer tools' route tracing feature enables you to do both. The Diagram View displays a graphical representation of the route. The Messages View displays the messages processed by the node selected in Fuse JMX Navigator. You can also display the full contents of a message in the Properties view.

Live debugging

Debugging a route in the Fuse Integration perspective enables you to see how the route functions in its actual deployment environment. The route is hooked up to live endpoints that are managed by live brokers. When you drag a test message on to a route's endpoint, you're adding it to that endpoint.

You can ensure that the start endpoint is properly configured to receive messages. As the message passes through each processor in the route, you can check the entire message, including all of the transport headers, to see if it is being processed correctly. You can also check that the target endpoint is properly configured to pass results to the intended target destination.

Visualization

Diagram View displays your routes as graphs. Each node of the graph represents a step in the route and is identified by an icon representing the EIP pattern the node represents.

With route tracing activated, you can trace, in Diagram View, each node that has processed a message by scrolling through the message list in Messages View.

9.4. JMS browsing

Overview

A browser that inspects the messages on a JMS destination without consuming them is key to troubleshooting a distributed message system. Inspecting the messages can help you understand why messages are backing up or why they are being discarded too soon.

In addition to inspecting JMS destinations, the debugging tooling allows you to add messages to them. This feature enables you to add controlled test cases into the system for detailed analysis.

Viewing messages

Fuse JMX Navigator shows all of the JMS destinations deployed in your infrastructure. When you select a destination from the tree, a list of the messages sitting in it are listed in Messages View. Messages View displays the basic properties of the message.

Selecting one of the messages in Messages View displays all of that message's details, including the full message body, in the Properties viewer.

Adding messages

You can simply drag messages from Project Explorer, Package Explorer, or Messages View and drop them on any JMS destination displayed in Fuse JMX Navigator or in Fabric Explorer.

Chapter 10. Opening the Fuse Integration Perspective

Revision History
	7/13/12	EMJ
added descriptions of all the views that make up the perspective

Overview

The Fuse Integration perspective provides access to all of the debugging tooling. It contains all of the views used to monitor and debug Fuse integration projects including:

Project Explorer
A standard Eclipse view that shows all of the projects known to the developer tools. You can view and select the artifacts that make up each project.
In Project Explorer, the debugging tooling displays all of the camel context files for a project under the project's Camel Contexts node. This makes it easy for you to find and open the context file of any route in a project.
Fuse JMX Navigator
A customized JMX view that allows you to browse JMX servers and the processes they are monitoring. The Fuse JMX Navigator automatically lists all of the JMX servers running on the local machine. It also can identify instances of Red Hat processes.
Diagram View
Displays a graphical tree representing the node selected in the Fuse JMX Navigator.
When you select a process, server, endpoint, or other node in Fuse JMX Navigator, the graphical tree in Diagram View shows the selected node as the root and branches down to the children and grandchildren. For example, if you select a broker in Fuse JMX Navigator the tree in Diagram View displays up to three children: connections, topics, and queues. It also shows configured connections and destinations as grandchildren.
When you select a route, the graphical tree includes all of the nodes in the route and the path that a message can take through it. If you select a context node, Diagram View shows all of the routes in the context.
Shell
Shows the command console of a container. You can control the connected container by entering commands into the shell.
Messages View
Displays the list of messages sitting in the node selected in Fuse JMX Navigator. This view is populated only when a JMS destination or route endpoint is selected.
See Chapter 13, Browsing messages for more details.
Note
Route endpoints contain messages only when route tracing is activated. See Section 14.3, “Tracing messages through a route” for more information.
Servers
Displays a list of the servers managed by the developer tools. It displays their runtime status and provides controls for stopping and starting them.
Console
Displays the console output for recently executed actions.
Properties
The Properties view displays the JMX properties for the node selected in Fuse JMX Navigator.

Opening the perspective

To open the Fabric Integration perspective, select Window → Open Perspective → Fuse Integration, or click new perspective button

in the Perspectives tab, and select Fuse Integration.

Chapter 11. The Fuse JMX Navigator

The Fuse JMX Navigator, shown in ???, displays all of the processes running in your application and drives all interactions with the debugging features. Other areas of the Fuse Integration perspective adapt to display information related to the node selected in the explorer. The explorer's context menu also provides the commands needed to activate route tracing and to add JMS destinations.

Figure 11.1. Fuse JMX Navigator

By default, the Fuse JMX Navigator discovers all of the JMX servers running on the local machine and lists them under the Local Processes tree. You can add other JMX servers using a server's JMX URL.

11.1. Viewing Processes in JMX

Overview

The Fuse JMX Navigator lists all known process in a series of trees. The root for each tree is a JMX server.

The first tree in the list is a special Local Processes tree that contains all of the JMX servers running on the local machine. You must connect to one of the JMX servers to see the processes it contains.

Viewing processes in a local JMX server

To view information about processes in a local JMX server:

Expand the Local Processes entry in the Fuse JMX Navigator.
Double-click one of the top-level entries under Local Processes to connect to the JMX server.
Double-click it to open a connection.
Click the icon that appears next to the entry to display the list of all components running in the JVM.

Viewing processes in alternate JMX servers

To view information about processes in an alternate JMX server:

Add the JMX server to the explorer.
Expand the server's entry in the Fuse JMX Navigator using the icon that appears next to the entry to display the list of all components running in the JVM.

11.2. Adding a JMX server

Overview

The Fuse JMX Navigator lists all of the local JMX servers under the Local Processes branch of the tree. You may need to connect to specific JMX servers to see components deployed on other machines.

To add a JMX server you need to know the JMX URL of the server you want to add.

Procedure

To add a JMX server to the Fuse JMX Navigator:

Click to the right of the Fuse JMX Navigator tab.
In the Create a new JMX connection wizard, select Default JMX Connection.
Click Next>.
Select the Advanced tab.
In the Name field, enter a name for the JMX server.
The name can be any string. It is used to label the entry in the Fuse JMX Navigator tree.
In the JMX URL field, enter the JMX URL of the server.
If the JMX server requires authentication, enter your user name and password in the Username and Password fields.
Click Finish.
The new JMX server is displayed as a branch in the Fuse JMX Navigator tree.

Chapter 12. Viewing a component's properties

Overview

The developer tools collect and display all of the JMX properties reported by Fuse components. This information can provide significant insight into what is happening in your integration application.

Procedure

To see a Fuse component's properties:

Locate the node for the component in the Fuse JMX Navigator.
You may have to expand nodes on the tree to locate low-level components.
Select the Fuse component's node from the tree.
Open the Properties view.
The selected component's properties will be displayed in table format.
You can use the Search box in Properties view to locate specific properties based on value.

Chapter 13. Browsing messages

Revision History
	8/15/11	EMJ
generalized for all endpoints and added list of things that can be browsed

Overview

A key tool in debugging applications in a distributed environment is seeing all of the messages stored in the JMS destinations and route endpoints in the application. The developer tools can browse the following:

JMS destinations
JMS routing endpoints
Apache Camel routing endpoints
SEDA routing endpoints
Browse routing endpoints
Mock routing endpoints
VM routing endpoints
DataSet routing endpoints

Procedure

To browse messages:

Select the JMS destination or endpoint from Fuse JMX Navigator.
The list of messages is displayed in the Messages View.
Select an individual message to inspect from the list of messages in the Messages View.
Message details and content are displayed in the Properties view.

Chapter 14. Tracing messages through routes

Debugging a route usually involves solving one of two problems:

a message was improperly transformed
a message failed to reach its destination endpoint

Tracing one or more test messages through the route is easiest way to solve these problems.

The route tracing feature of the developer tools enable you to monitor the path a message takes through a route and see how the message is transformed as it passes from processor to processor.

Diagram View displays a graphical representation of the route, which enables you to see the path a message takes through it. For each processor in a route, it also displays the average processing time, in milliseconds, for all messages processed since route start-up and the number of messages processed since route start-up.

Messages View displays the messages processed by a JMS destination or route endpoint selected in the Fuse JMX Navigator tree. Selecting an individual message in Messages View, displays the full details and content of the message in the Properties view.

Tracing messages through a route involves the following steps:

Creating test messages for route tracing
Activating route tracing
Tracing messages through a route
Deactivating route tracing

14.1. Creating test messages for route tracing

Overview

Route tracing requires that messages have a specific structure. They must have a message root element in the namespace http://fabric.fusesource.org/schema/messages.

Procedure

To create a test message:

In Project Explorer, right-click the project to open the context menu.
Select New → Fuse Message to open the Fuse Message File wizard.
In the RouteContainer field, enter the path of the folder in which you want to store the message.
Use the Browse... button to help locate the proper folder.
In the File name field, enter a name for the message.
Click Finish.
The new message opens in the XML editor.
Fill in the contents (body and header text) of the message.
On the menu bar, click File → Save to save the test message.

14.2. Activating route tracing

Overview

Before you can trace messages through a route, you must activate route tracing for the route's routing context.

Procedure

To start tracing on a routing context:

In the Fuse JMX Navigator tree, select the routing context on which you want to start tracing.
You can select any route in the context to start tracing on the entire context.
Right-click it to open the context menu, and then select Start Tracing.
If Stop Tracing Context appears on the context menu, tracing is already active.

14.3. Tracing messages through a route

Overview

The best way to see what's happening in a route is to watch what happens to a message at each stop along the route. The debugging tooling provides a mechanism for dropping messages into a route and tracing the message's path through it.

Procedure

To trace messages through a route:

Create one or more test messages as described in Section 14.1, “Creating test messages for route tracing”.
Activate tracing for the route's routing context as described in Section 14.2, “Activating route tracing”.
Drag one of the test messages onto the route's starting point.
In the Fuse JMX Navigator tree, select the route being traced.
The Messages View is populated with a list of messages representing the message at each stage in the traced route.
Open Diagram View to see a graphical representation of the selected route.
In the Messages View, select one of the messages.
In Diagram View, the route step in which the selected message is sitting is highlighted. The Properties view displays the full details and content of the test message.

You can repeat this process as needed.

14.4. Deactivating route tracing

Overview

When you are finished debugging the routes in a routing context, you should deactivate tracing for the routing context.

Important

Deactivating tracing stops tracing and flushes the trace data for all of the routes in the routing context. This means that you cannot review any past tracing sessions.

Procedure

To stop tracing for a routing context:

In the Fuse JMX Navigator tree, select the routing context for which you want to deactivate tracing.
You can select any route in the context to stop tracing for the context.
Right-click it to open the context menu, and then select Stop Tracing Context.
If Start Tracing appears on the context menu, tracing is not activated for the routing context.

Chapter 15. Managing JMS destinations

The developer tools' Fuse JMX Navigator allows you to easily add or delete JMS destinations from a running Red Hat JBoss Fuse A-MQ.

Important

These changes are not persistent across broker restarts.

15.1. Adding a JMS destination

Overview

When testing a new scenario, it is convenient to add a new JMS destination to one of your brokers. The developer tools provide a menu choice for adding a destination with a single click.

Procedure

To add a JMS destination to a broker:

In the Fuse JMX Navigator tree, select either the Queues child or the Topics child in the broker node where you want to add a destination.
Right-click it to open the context menu, and then select Create Queue/Topic.
In the naming dialog, enter a name for the destination.
Click OK.
The new destination appears in the tree.

15.2. Deleting a JMS destination

Overview

When testing fail over scenarios or other scenarios that involve failure handling, it's convenient to be able to easily remove a JMS destination. The developer tools have a menu option that allows you to remove a destination with a single click.

Procedure

To delete a JMS destination:

In the Fuse JMX Navigator tree, select the JMS destination you want to delete.
Right-click it to open the context men, and then select Delete Queue/Topic.

Chapter 16. Managing routing endpoints

The Fuse JMX Navigator allows you to easily add or delete routing endpoints.

Important

These changes are not persistent across router restarts.

16.1. Adding a routing endpoint

Overview

Procedure

To delete a routing endpoint:

In the Fuse JMX Navigator tree, select the endpoint you want delete.
Right-click it to open the context menu, and then select Delete Endpoint.

Chapter 17. Editing running routes

Revision History
	07/23/12	EMJ
Streamlined the steps about saving the changes

Overview

If you want to experiment with changes to a running route, you can make the edits directly from the Fuse Integration perspective. The developer tools open the context file containing the route in the route editor. When your changes are saved, they take effect immediately.

The changes are made to the in-memory model of the running context, but are not persisted as part of their original project or any other project.

Note

If you want to save the changes permanently, you must use the Save As menu option.

Procedure

To edit a running route:

In the Fuse JMX Navigator tree, select the context containing the route(s) you want to edit.
Right-click to open the context menu, and select Edit Routes.
Route editor displays the context and all of its routes.
Edit the route(s) as described in Part I, “Developing Applications”.
When done, save the edited route.
- Select File → Save to update the in-memory version of the routing context.
  Changes take effect immediately.
- >Select File → Save As to save the edited routing context in a new context file.

Chapter 18. Managing routing contexts

The Fuse JMX Navigator enables you to easily suspend, shutdown, and resume routing contexts.

18.1. Suspending a routing context

Overview

The developer tools enable you to suspend the operation of a routing context from Fuse JMX Navigator. Suspending a context gracefully shuts down all of the routes in the context, but keeps them loaded in memory so that they can easily be resumed.

If you want to kill all of the routes and free their resources, close the context. See Section 18.3, “Shutting down a routing context”.

Procedure

To suspend a routing context:

In the Fuse JMX Navigator tree, expand the project's Camel Contexts node, and select the routing context you want to suspend.
Right-click it to open the context menu, and then select Suspend Camel Context.
Note
If Resume Camel Context appears on the context menu, the context is already suspended.

18.2. Resuming a routing context

Overview

The developer tools enable you to resume a suspended routing context from Fuse JMX Navigator. Resuming a context restarts all of the routes in it, so that they can process messages.

Procedure

To resume a routing context:

In the Fuse JMX Navigator tree, expand the project's Camel Contexts node, and select the routing context you want to resume.
Right-click it to open the context menu, and then select Resume Camel Context.
Note
If Suspend Camel Context appears in the context menu, the context and its routes are running.

18.3. Shutting down a routing context

Overview

The developer tools enable you to shut down a routing context from Fuse JMX Navigator. Shutting down a routing context gracefully stops all of the routes in the context and releases all of the resources used by the routes. Once shut down, a routing context cannot be resumed.

If you want to stop the routes so that they can be restarted, suspend the context. See Section 18.1, “Suspending a routing context”.

Procedure

To shut down a routing context:

In the Fuse JMX Navigator tree, expand the project's Camel Contexts node, and select the routing context you want to shut down.
Right-click it to open the context menu, and then select Close Camel Context.

Chapter 19. Managing servers

Revision History
	07/24/2012	EMJ
Added section about removing servers

The Servers panel enables you to deploy and manage servers in your Eclipse environment. The debugging tooling supports deploying the following servers:

Red Hat JBoss Fuse 6.x Server
Apache Karaf 2.x Server
Apache ServiceMix 4.x Server

19.1. Adding a Server

Revision History
	07/24/2012	EMJ
Added overview
	07/24/2012	EMJ
Corrected procedure

Overview

To make it possible for the developer tools to manage a server, it needs to be added to the Servers list. Once added, the server will appear in the Servers view and in the Servers tree in both Project Explorer and Package Explorer.

You can add multiple servers of the same type, as long as each uses a separate installation directory.

Note

If adding a Red Hat JBoss Fuse server, it's recommended that you edit its installDir/etc/users.properties file and add user information, in the form of user=password,role, to enable the developer tools to establish an ssh connection to the server.

Procedure

To add a new server to the Servers list:

From the main menu, select File → New → Other to open the New wizard.
Select Server → Server from the list.
Click Next>.
In the Define a New Server dialog, select the type of server you want to create from the list.
In Server's host name, accept the default (localhost) or enter the name of the host on which the server runs.
Note
Currently the debugger does not support servers running on remote machines.
In Server name, accept the default, or enter a different name for the server.
If the Server runtime environment drop-down list is present (when Red Hat JBoss Fuse 6.x is selected), accept the default or select another runtime environment from the list.
Click Next>.
If you have not defined a server of this type before, you must do so now in the New ServerType Runtime dialog.
1. In Installation directory, enter the full path to the server's installation folder.
  The button opens a file browser.
2. Click Next>.
Host Name defaults to the address of the machine running the server. For localhost, the address is 0.0.0.0.
In Port Name, accept the default (8101), or enter the port number that the debugger will use to connect to the server.
In User Name, enter the user name that the debugger will use to connect to the server.
For a Red Hat JBoss Fuse server, this is a user name that is stored in the installDir/jboss-fuse-6.0.0.redhat-xxx/etc/users.properties file.
If one has not been set, you can either add one to that file using the format user=password,role (for example, admin=admin,admin), or you can set one using the karaf jaas command set:
- jaas:realms—to list the realms
- jaas:manage --index 1—to edit the first (server) realm
- jaas:useradd <username> <password>—to add a user and associated password
- jaas:roleadd <username> admin—to specify the new user's role
- jaas:update—to update the realm with the new user information
If a jaas realm has already been selected for the server, you can discover the user name by issuing the command JBossFuse:karaf@root>jaas:users.
In Password, enter the password associated with the user name that the debugger will use to connect to the server.
For a Red Hat JBoss Fuse server, this is the password set either in the installDir/jboss-fuse-6.0.0.redhat-xxx/etc/users.properties file or by the karaf jaas comands.
Click Next>.
The New ServerType Add and Remove page opens.
Move the resources you want the server to use from the Available column to the Configured column.
Click Finish.

The new server appears in the list of servers in the Servers panel.

Part III. Working with Fabrics

A fabric is a distributed configuration, provisioning, and clustering mechanism for running Red Hat JBoss Fuse Plugins for Eclipse projects on multiple computers in an on-premises or public Cloud. You can view and edit fabrics, and the containers, versions, and profiles of which they consist. You can also create and delete containers and profiles, but you can only create versions.

Chapter 20. The Fuse Fabric perspective

The Fuse Fabric perspective, shown in Figure 20.1, is where you access the fabric development and debugging tools.

Figure 20.1. Fuse Fabric perspective

The Fuse Fabric perspective consists of six main areas:

Fabric Navigator—lists the fabrics and the containers, profiles, and versions of which they consist.
Diagram View—provides a graphical representation of a node selected in Fabric Navigator.
Shell— provides console access to any container running on the fabric.
Log view—lists the log entries of the selected container or the selected JMX process.
Messages View—lists the message instances that passed through the nodes in a selected route, after tracing was enabled on the route.
Properties view—displays the properties of an object selected in Fabric Navigator.

Fabric Navigator

Fabric Navigator provides access to your fabrics. Once the developer tools are connected to a fabric, Fabric Navigator provides access to all of the fabric's components (containers, profiles, and profile versions) enabling you to configure, run, and debug your project in the fabric environment.

Diagram view

Use Diagram View in conjunction with Messages View to track a message through the nodes of a route for which tracing has been activated. In Diagram View, the node which corresponds to the message instance selected in Messages View is highlighted. Messages View displays metrics for the selected message instance, including the time at which it exited the highlighted node.

Log view

Log view displays the log entries of the container selected in Fabric Navigator. This feature enables you to see the log messages of any container running in a fabric.

Double-clicking a process in a container's JMX tree opens the process in a jconsole-like viewer, where you can browse its attributes, operations, notifications, and other information, all of which are presented in tabular format.

Messages view

The Messages View is used for tracing messages through a route in a fabric environment.

When an Apache Camel route for which route tracing has been activated is selected in Fabric Navigator, Messages View lists all messages that pass through the route from the time tracing was activated. Messages View also provides metrics for each message instance, making it easier to debug routes.

Use the view's Refresh button periodically to update its display of message traces.

Properties view

For container nodes, the Properties view also provides the Profiles tab, for viewing the profiles assigned to the container, and the Profile Details tab, for viewing the details of each assigned profile.

The Profiles editor enables you to change the profiles associated with the selected container, and the Profile Details editor enables you to modify the configuration of the selected profile.

JMX viewer

Chapter 21. Setting up a Fabric Environment

The developer tools provide an environment for developing and debugging fabric applications. Use the developer tools to build a mock-up of your actual fabric into which you can deploy your application to test and debug it.

Overview

To set up a fabric environment, you must have access to an existing fabric.

Setting up a fabric environment involves several basic steps:

Providing the details for connecting to an existing fabric
Connecting to the fabric
Creating the containers that will host the various components of your distributed integration application
Assigning each container one or more profiles, which provision containers by deploying and installing specified applications.

Note

For cloud applications, unless the cloud already has a fabric registry agent running on it, you must create one yourself, before you can include it to your fabric environment. For details, see Chapter 26, Creating a Fabric in the Cloud.

Opening the fabric perspective

To set up a fabric environment, you must switch to the Fuse Fabric perspective, by selecting Window → Open Perspective → Fuse Fabric, or clicking new perspective button

in the Perspectives tab, and selecting Fuse Fabric.

Chapter 22. Specifying and Connecting to a Fabric

Before you can view and edit your fabric, you must add it to the Fabric Navigator view. You can add multiple fabrics in Fuse Fabric perspective and connect to them concurrently.

22.1. Adding fabric details

Overview

For the developer tools to connect to a fabric, you must provide certain details about the fabric.

Procedure

To specify the details for connecting to a fabric:

In Fabric Navigator, right-click Fabrics to open the context menu, and then select Add Fabric details to open the Fabric Details wizard, as shown in Figure 22.1.
Figure 22.1. Fabric Details wizard
In Name, enter the name of the fabric to which you want to connect. The name you enter identifies the fabric whose location you specify in URLs, and this name will appear in Fabric Navigator.
The default Name is Local Fabric.
In URLs, enter the url, in the form hostname:port, of the fabric to which you want to connect. This URL specifies the location of a fabric registry agent, whose default port is 2181.
The default URL is localhost:2181.
In User name, enter the name used to log into the specified fabric.
This is the new user name specified when the fabric was created or is stored in Red Hat JBoss Fuse Plugins for Eclipse's installDir/etc/users.properties file. In that file, user information is specified using this format: user=password,role (for example, admin=admin,admin).
You can also discover the user name by issuing the command JBossFuse:karaf@root>jaas:users, if the Jaas realm has been selected for the fabric.
In Password, enter the password required for User name to log into the specified fabric.
This is the password specified for the new user name when the fabric was created or is stored in Red Hat JBoss Fuse Plugins for Eclipse's installDir/etc/users.properties file.
In Zookeeper Password, enter the password required for logging into the specified fabric's zookeeper registry.
This is the password that was specified or generated when the fabric was created, or it is the user's password stored in Red Hat JBoss Fuse Plugins for Eclipse's installDir/etc/users.properties file.
You can also discover the Zookeeper password by issuing the command JBossFuse:karaf@root>fabric:ensemble-password.
Click OK.
The fabric's name appears in Fabric Navigator as a node beneath Fabrics.
Note
Before you can view or modify a fabric's containers, profiles or versions, you must connect to the fabric. For details see Section 22.2, “Connecting to a fabric”

22.2. Connecting to a fabric

Overview

The developer tools connect to a fabric using the connection information you specified for it in the Fabric Details dialog.

Procedure

In OS Family, select from the drop-down list the family name of the operating system you want to use.
If you select an OS Family, do not also select an Image ID.
In OS Version, optionally select from the drop-down list the version for the operating system you selected.
If you selected an OS Family, skip this step. Otherwise, in Image ID, select from the drop-down list the ID of the image template to use for the software configuration.
Note
The developer tools start an instance of the image in the cloud, and then install a fabric agent and provisions the new agent with the selected profiles. Depending on the cloud provider, instantiation and provisioning could take some time.
Under Profiles, select the profile or profiles you want to assign to the container.
Profiles determine the function of containers—what applications they run. You can assign a container multiple profiles, as long as the applications they install do not conflict with one another.
Important
Do not assign a base profile (one ending in -base) to a container.
Click OK.
The new container appears in Fabric Navigator as a container node under Containers
Note
Selecting the new container in Fabric Navigator populates its Profiles and Profile Details pages in Properties viewer.

23.4. Starting a container

Overview

When you create a container, it starts up automatically and continues to run until stopped by some event, planned or otherwise. You can manually restart a stopped container.

Procedure

To start a container:

If necessary, in Fabric Navigator, expand the tree of the fabric whose container you want to start.
Select the container and right-click it to open the context menu.

Click Start Container.

Note

To check whether the developer tools started the container, click Containers in Fabric Navigator, and open the Properties view. You should see something similar to Figure 23.5, where mycamelExample was started and provisioned successfully.

Figure 23.5. Container status in Properties view

The status indicators in the Status column of the Properties view indicate the startup state of the container, as shown Table 23.1:

Table 23.1. Container startup status

Icon	Meaning
	Container stopped
	Container started; analysis and provisioning in progress
	Container started and provisioned successfully
	Failure occurred during startup or provisioning

23.5. Changing a Container's Profiles

Overview

A container's profiles determine what the container is hosting. If you want to change what is deployed in a container or how it is configured, you change the profiles deployed to it.

Procedure

To change the profiles deployed to a container:

Select the container.
In the Properties view, select the Profiles tab.
Select the profile to be deployed to the container.
Important
You selection will override the list of profiles currently deployed to the container.
Note
You can select multiple profiles by holding the CTRL key

23.6. Stopping a container

Overview

There are times when you might want to stop then restart a container; for example, to recycle a hung container, force a container to reprovision itself, or to reclaim CPU cycles.

Procedure

To stop a container:

If necessary, in Fabric Navigator, expand the tree of the fabric whose container you want to stop.
Select the container and right-click it to open the context menu.
Click Stop Container.
Note
To check whether the developer tools stopped the container, click Containers in Fabric Navigator, and open the Properties view. You should see something similar to Figure 23.6, where myRoute was stopped successfully.
Figure 23.6. Container status in Properties view
For information on the meaning of the status indicators that might appear in the Status column of the Properties view, see Table 23.1, “Container startup status”.

23.7. Deleting a container

Overview

When a container becomes obsolete—no longer used in the fabric integration project—you may want to delete it. Before you do so, make sure no other container in the project depends on it. Deleting a container terminates the container and its processes and removes its configuration from the fabric.

Note

To delete a container, it must be running in the fabric.

Procedure

To delete a container:

If necessary, in Fabric Navigator, expand the tree of the fabric whose container you want to delete.
Click Containers to populate Properties view with a list of the fabric's containers.
In Properties view, select the container you want to delete, and then click on the right-hand side of the toolbar.
Figure 23.7. Container selected for deletion in Properties view
In the Destroy Container(s) dialog, click OK to delete the selected container.
The developer tools display a message that removal is in progress. In Properties view, the container's status briefly changes to stopped, and then the container disappears from the list.
In Fabric Navigator, open the fabric's context menu, and click Refresh to update Containers and remove the deleted container from the tree.
Note
If you have the Red Hat JBoss Fuse console open in Shell view, you can verify that the container and its configuration have been removed from the fabric by entering at the command line fabric:container-list.

Chapter 24. Working with Fabric Profiles

Profiles are applied to fabric containers, and they determine the function and behavior of their containers. A profile consists of code and configurations, which specify the type of service or application a container runs. The code may come from OSGi bundles, Fab Application Bundles (see, Fab Deployment Model in the Red Hat JBoss Fuse Deploying into the Container guide), and Karaf features pulled from repositories, also specified in the profile. Defined hierarchically, profiles can be set up to inherit from other profiles, building on their parents' definitions.

24.1. Creating a new profile

Overview

The developer tools provide access to numerous profiles, each of which imparts specific functionality and behaviors to the containers to which it's assigned. But you may want to create new profiles that inherit from these base profiles, so you can override, for example, configuration details. You may also want to create your own profiles to deploy your own code. To do so, you create a new profile based on an existing one, and then change its configuration and properties to generate the specific behaviors you want to deploy to the target containers.

Note

This procedure creates a brand new profile. If you want to create a new version of an existing profile to incrementally test changes to deployed containers, see Chapter 25, Working with Versions

Procedure

To create a new profile:

In Fabric Navigator, expand the fabric in which you want to create a new profile.
Expand the fabric's tree to the level of the profiles, as shown in Figure 24.1.
Figure 24.1. Accessing the profiles
Select the profile on which you want to base the new profile, and right-click it to open the context menu.
Important
Because the base profile is the parent of the new profile, the new profile inherits the base profile's configurations, properties, features, repositories and bundles as well as those of the base profile's ancestors. However, a child's configurations override an ancestor's when their configuration files have the same name.
Note
Neither configuration files nor properties are visible within the developer tools, but you can view them in the Red Hat JBoss Fabric Management Console. For details, see the Red Hat JBoss Fabric Management documentation.
Select Create a new Profile.
Figure 24.2. Create Profile dialog
In Profile name, enter a name for the new profile.
Use a name that is descriptive of the new profile's function.
Click OK to create and save the new profile.
The new profile is added to the list of profiles in Fabric Navigator, under its parent profile.
In Fabric Navigator, select the new profile to populate the Properties editor with the new profile's properties information and profile details.
In the Properties editor, click the Details tab.
Figure 24.3. Profiles page
On the Profiles page, you can add, delete, or edit features, the repositories from which features are downloaded, and bundles. You can also or add or remove parent profiles. Profiles can have multiple parents, and they inherit the qualities of each
Features are files that aggregate references to interdependent or related bundles that together define a feature. Typically, you'd use bundles only if the feature they define is not already included in a features file. For more information on bundles and features, see Fab Deployment Model in the Red Hat JBoss Fuse Deploying into the Container guide.
Child profiles inherit everything (configurations, properties, features, repositories, and bundles) from their immediate parents and from all of their parents' ancestors. When the child's and any ancestor's configuration file have the same name, the child's configuration file replaces the ancestor's file. Otherwise, configurations are cumulative.
Note
The Profiles page displays only the features, repositories, and bundles added by the child profile, not those contributed by the profile's parents or other ancestors. The Parents pane shows (highlighted) the profile's immediate parents only.
Make the changes you want to the new profile to configure it.
Changes are automatically saved as you make them.
Note
In Fuse Integration perspective, you can easily add a Fuse project to the new profile by dragging it from Project Explorer and dropping it onto the new profile in Fabric Navigator. When you do, the fabric tooling builds the project, runs all tests, installs the project in the new profile, and uploads the profile into the fabric's internal Maven repository. Because profiles are stored in a fabric's internal repository, they cannot be shared across other fabrics.
Important
If you drop your project on a fabric container, rather than on a profile, the next time that container gets provisioned, your project is wiped out.
You can now assign the new profile to a container.
In Fabric Navigator, select the container to which you want to assign the new profile.
The fabric tooling populates the Properties editor with the container's properties information and profile details.
Open the container's Details tab, and then select the new profile in the Profiles list.
Repeat Step 10 and Step 11 for each container to which you want to assign the new profile.

24.2. Deleting a profile

Overview

When a profile is inactive—no longer assigned to any container in the fabric—you can safely delete it.

Procedure

To delete an inactive profile:

In Fabric Navigator, expand the fabric which contains the profile you want to delete.
Expand the fabric's tree to the level of versions, and then expand the version that contains the target profile.
Select the target profile, and right-click it to open the context menu.
Select Delete Profile.

Chapter 25. Working with Versions

Versioning provides the means for safely rolling out upgrades of the profiles deployed and running in containers across a fabric. Using versioning, you can make incremental updates to existing profiles, and then test them out on small groups of containers. When you've completed and tested the final versions, you can confidently deploy them to their target containers in the fabric.

25.1. Creating a new version of a profile

Overview

A version is simply the collection of all profiles associated with a fabric. When you create a new version, you are copying all of the profiles from the most recent version—the base version—into the new version. Once that's done, you can upgrade the profiles in the new version by modifying them.

Creating a new version

To create a new version:

In Fabric Navigator, select the fabric in which you want to create a new version.
Expand the fabric's tree to the level of Versions, shown in Section 24.1, “Creating a new profile”.
Select a version, and then right-click it to open the context menu.
Select Create Version.
In the Create Version wizard, enter a new version or accept the default value.
The default version is always a minor increment of the highest-numbered version. So, if the highest-numbered version is 1.3, the new version will default to 1.4, and all of the profiles in version 1.3 will be copied into version 1.4.
Important
Version names are important! The developer tools sort version names based on the numeric version string, according to major.minor numbering, to determine the version on which to base a new one. You can safely add a text description to a version name as long as you append it to the end of the generated default name like this: 1.3<.description>. If you abandon the default naming convention and use a textual name instead (for example, Patch051312), the next version you create will be based, not on the last version (Patch051312), but on the highest-numbered version determined by dot syntax.
Click OK.
The developer tools copy all of the base version's profiles into the new version and display the new version in Fabric Navigator, directly under the base version.

Modifying profiles in the new version

To modify a profile in the new version:

In Fabric Navigator, expand the newly created version.
Select a profile that you want to modify.
The developer tools populate the Properties editor with the profile's details for you to edit.
In the Properties editor, click the Details tab to access the Profiles page.
Make the changes you want to the new profile to configure it.
Changes are automatically saved as you make them.
Note
In Fuse Integration perspective, you can easily add a Fuse project to the new profile by dragging it from Project Explorer and dropping it onto the new profile in Fabric Navigator. When you do, the developer tools build the project, run all tests, install the project in the new profile, and upload the profile into the fabric's internal Maven repository. Because profiles are stored in a fabric's internal repository, they cannot be shared across other fabrics.

25.2. Setting a container's version

Overview

After you've created a new version, you can assign it to selected containers. This feature enables you to easily roll out upgraded profiles in a controlled and orderly way.

Important

Setting a container's version immediately provisions the container with the profiles from the selected version.

Procedure

To set a container's version:

In Fabric Navigator, select the container whose profiles you want to change.
Right-click it to open the context menu, and then select Select Version.
The Select Version submenu lists all available versions.
Click the version you want to assign the selected container.
The container is immediately provisioned with the new version of any profile assigned to it.

Chapter 26. Creating a Fabric in the Cloud

To create a fabric on a cloud, you need to

Have established an account with a cloud provider
Provide the developer tools the account details for connecting to the cloud
Specify the details required for creating the fabric and the machine image on which it will run

26.1. Adding cloud details

Overview

To connect to a cloud, the developer tools need the relevant access and authorization information. This information was provided to you or a system administrator by the cloud provider, when the account was set up.

Procedure

To add a cloud's access details:

In Fabric Navigator, right-click Clouds to open the context menu, and then select Add Cloud details.
Figure 26.1. Cloud Details wizard
Note
An error icon ( ) marks required fields that lack a valid value, and the dialog banner displays the number of errors detected.
In Name, enter a name for the cloud.
Important
The next three fields provide two methods for specifying the provider's information. You select either a provider's name, or you select both an API and its endpoint.
In Provider name, select the name of the cloud provider from the drop-down list.
If you select a provider name, the developer tools autofill Api name and Endpoint with the selected provider's information, so you can skip to Step 6.
In Api name, select from the drop-down list the name of the API you want to use.
This list displays only APIs that have been installed on your local machine or environment.
In Endpoint, enter the uri of the web service that exposes the API you selected in Step 4.
If you have an on-premises, private cloud installed, you need to get this uri from the cloud administrator.
In Identity, enter the account identifier supplied by the cloud provider.
For example, for Amazon Elastic Compute Cloud (EC2) accounts, you'd enter the Access Key ID.
In Credential, enter the account password supplied by the cloud provider.
For example, for Amazon Elastic Compute Cloud (EC2) accounts, you'd enter the Secret Access Key.
In Owner, for EC2 only, enter the id assigned to a custom image.
This option is EC2-specific and applies only to custom images. To query or use a custom image, you must enter the owner id assigned to it by EC2; otherwise, the image will not appear in the list of instances.

If you entered valid access details, the developer tools connect to the cloud whose access details you specified and load the provider's images. Once that's done, the name you entered in Step 2 appears as a node under Clouds in Fabric Navigator.

26.2. Specifying fabric details

After you've added the access information that the developer tools need to connect to a cloud, you can create a fabric on the cloud. This procedure assumes that you have already added the cloud details.

Overview

Creating a fabric on a cloud involves creating on the cloud a container that contains a fabric registry and specifying the machine image on which you want to create and run it.

Procedure

To create a fabric on a cloud:

In Fabric Navigator, right-click Fabrics to open the context menu, and then select Create Fabric in the cloud.
On the Create Fabric in the cloud wizard's Choose the Cloud page, select the cloud from the list, and then click Next to open the wizard's Fabric Details page.
Figure 26.2. Fabric Details page
Note
An error icon ( ) marks required fields that lack a valid value, and the dialog banner displays the number of errors detected.
You may have to wait a few seconds while the developer tools retrieve the location, hardware, and image IDs from your cloud provider to populate the wizard's corresponding fields.
In Fabric Name, accept the default name, or enter a different name for the new fabric.
In Container name, accept the default name, or enter a different name for the new container that will host the fabric registry.
In Group, accept the default name, or enter a different name for the group in which to start up the new fabric registry container.
In User, accept the default name, or enter a different user name to use for logging into the new fabric registry container.
In Location ID, select from the drop-down list the ID of the region in which the machines you want to use are located.
In Hardware ID, select from the drop-down list the ID of the hardware archetype you want to use.
Hardware archetypes specify the amount of memory and compute power available for running applications on machine images.
Important
The next three fields provide two methods for specifying the software configuration (operating system, application server, and applications) you want to use. Either select an OS Family (and optionally a version), or select an Image ID.
In OS Family, select from the drop-down list the family name of the operating system you want to use.
If you select an OS Family, do not also select an Image ID.
In OS Version, optionally select from the drop-down list the version for the operating system you selected.
If you selected an OS Family, skip this step. Otherwise, in Image ID, select from the drop-down list the ID of the image template to use for the software configuration.
In Maven proxy URI, accept the default URI, or enter the URI to the Maven proxy repository you want to use.
Click Finish.
The developer tools create the container, then provision it with all of the bundles, features, and profiles required to create a fabric registry. This process can take up to ten minutes. When it's done, the container specified in Step 4 appears in Fabric Navigator as a node under Fabrics.
Note
It's a good idea to access your cloud account and verify that the new fabric registry container is up and running.
