  7. Restart the server at this point or wait till other configuration changes have been made.

3.2. Modifying Security Settings

For the Business Central application to work, you need to modify several security settings on IBM WebSphere Application Server. To enable the container-managed authentication mechanisms provided by the server:

  1. In the main menu, click Security → Global Security. Ensure that the option Enable Application Security is checked. This may already be checked and overridden at the server level.

    Figure 3.6. Global Security Configuration Page

    global security

  2. Click Custom Properties on the right side and then New…​ to enter a new custom property with the following details:

    • Name: com.ibm.ws.security.web.logoutOnHTTPSessionExpire
    • Value: true

    This property instructs the server to invalidate LTPA tokens on session invalidation, which makes the logout process consistent across multiple users using the same browser.

  3. Click Apply and then OK.

3.3. Creating Users and Groups

  1. In the main menu on the left, click Users and Groups → Manage Groups.

  2. Create two new groups: admin and analyst by clicking Create…​.

    Figure 3.7. Created Groups

    created groups brms
    Note

    Add the kie-server group as well if you are going to install the Realtime Decision Server. Also add the REST API groups if you are going to use the API. For further information about API roles, see chapter Remote API of Red Hat JBoss BPM Suite Development Guide.

  3. In the main menu on the left, click Users and Groups → Manage Users.

  4. Click Create…​ and fill in the user credentials.

    Important

    Make sure that the selected User ID does not conflict with any known title of a role or a group.

    For example, if there is a role called admin, you should not create a user with the user name admin.

    Figure 3.8. Create User Dialog Window

    creating user

  5. Click Group Membership and assign the user to the admin group that you created previously.

    Note

    You may assign this user to any of the groups you have just created. In the production systems, you are likely to create separate users for separate groups that align with business roles. The admin group is all encompassing and is therefore useful for the purposes of this setup.

  6. Click Create.

3.4. Session Management Custom Settings

  1. In the main menu on the left, go to Servers → Server Types → WebSphere Application Servers and select the server on which you are deploying Business Central.
  2. Click Session Management under the Container Settings heading on the right.
  3. In the Additional Properties section on the right, click Custom Properties and then New…​.

  4. Fill in the required information:

    • Name: InvalidateOnUnauthorizedSessionRequestException
    • Value: true
  5. Click Apply and then OK.

3.5. Setting up Data Source

The Business Central application requires a data source which must be created prior to the deployment of the actual WAR file. This means that you must have access to an underlying database to which the data source connects. Whatever your underlying database, make sure you have the data source ready. Follow the steps below to set the data source.

Note

In the following procedure, the data source setup is demonstrated on the Oracle Database 12c.

Creating JDBC Providers

  1. Open up the JDBC Providers page by clicking Resources → JDBC → JDBC Providers.

  2. At the top of the JDBC Providers page, click Scope. Select the scope of this JDBC provider to include your server and node. Note that it cannot be All scopes.

    Figure 3.9. Selecting Scope of JDBC Provider

  3. Click New…​.

    The Create a New JDBC Provider page opens.

  4. Fill in the form based on the database driver that you have available.

    Figure 3.10. First Step of Creating New JDBC Provider

    creating jdbc provider1

    If your database is not listed, select the User-Defined option from the Database Type selection box and provide the implementation class name.

    For example, for H2, PostgreSQL, or MySQL, the implementation class name will be org.h2.jdbcx.JdbcDataSource, org.postgresql.xa.PGXADataSource, and com.mysql.jdbc.jdbc2.optional.MysqlXADataSource respectively.

  5. Give the JDBC Provider a descriptive name and click Next.

  6. Provide the class path information for the JDBC driver class files you defined. Click Apply.

    Figure 3.11. Defining Database Class Path

    creating jdbc provider2
  7. Click Next.

  8. Click Finish to accept and add this new JDBC provider.

    Figure 3.12. JDBC Provider Summary Page

    creating jdbc provider3

Using this new JDBC provider, you will now need to set up the actual data source for Business Central.

Before you create the data source, open the persistence.xml file located in the WEB-INF/classes/META-INF directory of the Business Central WAR file (business-central.war) that you have downloaded. You will need to know the JNDI name of the data source defined within the <jta-data-source> tag. For Business Central, it is jdbc/jbpm.

Also change the hibernate.dialect property to suit your database. For example, if your underlying database is Oracle Database 12c, change the property value to org.hibernate.dialect.Oracle10gDialect.

Setting up Data Source

  1. Open the Data Sources page by clicking Resources → JDBC → Data Sources in the main menu on the left and make sure that the appropriate scope has been selected.
  2. Click New…​.

  3. Enter a unique Data Source Name by which you will refer to this data source and the JNDI name that you found in the persistence.xml file.

    Figure 3.13. First Step of Creating New Data Source

    creating data source3

  6. In the Setup Security Aliases screen, set the authentication values for connecting to this data source. If the aliases are not yet created, click Global J2C Authentication Alias at the bottom. Note that in this case, the Create a Data Source wizard will be canceled.

    1. Click New…​.

    2. Fill in the Alias, User ID, and Password.

      Figure 3.16. Creating New Security Alias

      security alias
    3. Click OK.

    Go back to the Setup Security Aliases screen and set the Component-Managed Authentication Alias to the newly created alias and the Mapping-Configuration Alias to DefaultPrincipalMapping.

    You can also create and set a different alias for XA recovery. If the Authentication Alias for XA Recovery is set to (none), the component-managed authentication alias is used by default.

    Figure 3.17. Setting Security Aliases

    creating data source4

    Click Next.

  7. In the Summary screen, check the values and click Finish. Choose to save the changes to the master configuration as well.

    Figure 3.18. Creating Data Source Summary Screen

    creating data source5
  8. Choose the created data source from a list of all data sources to provide the basic meta properties.

  9. Click Custom Properties under the Additional Properties section on the right.

    Properties like serverName, databaseName, userName, and password must now be defined and vary for different databases. Some example database properties are shown below.

    Table 3.1. Custom Properties for Different Databases

    DatabaseProperties

    H2

    URL, user, password

    MySQL

    serverName, databaseName, port, user, password

    PostgreSQL

    serverName, databaseName, portNumber, user, password

    Oracle

    jdbcURL

Once all the connection properties have been defined, click Test Connection to ensure the validity of the data source. If the connection was successful, the following message appears at the top of the screen: 

The test connection operation for data source DATA_SOURCE_NAME on server SERVER_NAME at node NODE_NAME was successful.

3.6. Setting up JMS Resources

IBM WebSphere Application Server must be configured to send and receive JMS messages through Red Hat JBoss BRMS. However, before you do this, a service bus must be present. Follow the steps below to create a service bus if one does not already exist.

Setting up Buses

Creating Service Bus
  1. In the main menu on the left, click Service Integration → Buses.
  2. Click New…​.
  3. Enter the name and make sure that the Bus Security option is unchecked.
  4. Click Next and then Finish to create the service bus.
Adding Bus Member

Before you continue, add a new bus member. A bus member is a server or a cluster that has been added to this service bus.

  1. Go to Service Integration → Buses and click on the service bus that you have created.
  2. Under the Topology heading on the right, click Bus Members.
  3. Click Add.
  4. In the Add a New Bus Member wizard, choose the server and the type of message store for the persistence in the first two steps. Depending on the previous selection, you can also specify the properties of the message store.
  5. Click Finish in the last step to add a new bus member.

Creating JMS Connection Factories

To send and receive messages from Red Hat JBoss BRMS, you have to create the JMS connection factories, which are needed for establishing connections used for sending messages into queues.

Red Hat JBoss BRMS needs the Java Messaging Services only for the Realtime Decision Server. Use the procedure below to create the following connection factories: KIE.SERVER.REQUEST, KIE.SERVER.RESPONSE, and KIE.SERVER.EXECUTOR.

Note

The factory names shown above are suggestions only and you can change them to suit your needs and company guidelines.

  1. In the main menu on the left, go to Resources → JMS → Connection Factories.
  2. Make sure the correct scope is selected and click New.
  3. Select the Default Messaging Provider option and click OK.

  4. Enter the name and the JNDI name of the factory. For example:

    • Name: KIE.SERVER.REQUEST
    • JNDI name: jms/conn/KIE.SERVER.REQUEST
    Note

    The JNDI names for KIE.SERVER.RESPONSE and KIE.SERVER.EXECUTOR are jms/conn/KIE.SERVER.RESPONSE and jms/conn/KIE.SERVER.EXECUTOR respectively.

  5. From the Bus Name drop-down list, select the service bus created earlier.

    The rest of the options are not mandatory and can be left with default values.

  6. Click Apply and choose to save the changes to the master configuration.

Creating JMS Queues

The next step is to create the JMS queues. These queues are the destination end points for point-to-point messaging.

For Realtime Decision Server, create the following queues: KIE.SERVER.REQUEST (for requests), KIE.SERVER.RESPONSE (for responses) and KIE.SERVER.EXECUTOR (for executor services).

Important

To prevent warnings in the log, create KIE.EXECUTOR queue as well.

To create these queues:

  1. In the main menu, go to Resources → JMS → Queues.
  2. Make sure the correct scope is selected and click New.
  3. Select the Default Messaging Provider radio button and click OK.

  4. Enter the name and the JNDI name of the queue, for example:

    • Name: KIE.SERVER.REQUEST
    • JNDI name: jms/KIE.SERVER.REQUEST
    Note

    All of the JNDI names of other queues follow the same convention as the example above.

  5. From the Bus Name drop-down list, select the service bus created earlier.

  6. From the Queue Name drop-down list, make sure to select the Create Service Integration Bus Destination.

    This will open up the Create New Queue form for creating a new service integration bus. In this form, enter a unique identifier and select the bus member created earlier in this section.

  7. Click Apply at the bottom and choose to save the changes to the master configuration.

Creating JMS Activation Specifications

A JMS activation specification is required to be the bridge between the queue and the message-driven bean.

For Realtime Decision Server, create the following activation specifications: KIE.SERVER.REQUEST (for requests), KIE.SERVER.RESPONSE (for responses) and KIE.SERVER.EXECUTOR (for executor services).

Important

To prevent warnings in the log, create KIE.EXECUTOR activation specification as well.

  1. In the main menu, go to Resources → JMS → Activation Specifications.
  2. Make sure the correct scope is selected and click New.
  3. Check the Default Messaging Provider radio button and click OK.

  4. Enter the name and the JNDI name of the activation specification, for example:

    • Name: KIE.SERVER.REQUEST
    • JNDI name: jms/activation/KIE.SERVER.REQUEST
    Note

    All of the JNDI names of other activation specifications follow the same convention as the example above.

  5. From the Destination Type drop-down list, make sure to select Queue.
  6. Enter the Destination JNDI Name (as created in the previous procedure), for example jms/KIE.SERVER.REQUEST.
  7. From the Bus Name drop-down list, choose the service bus created earlier.
  8. Click OK at the bottom with the rest of the field values as default and choose to save the changes to the master configuration.

You have now successfully completed the JMS configurations required for setting up Red Hat JBoss BRMS on IBM WebSphere Application Server.

3.7. Adding Custom JVM Properties

You must add custom properties to the JVM that is used to start IBM WebSphere Application Server. These custom properties take into consideration the configuration changes that have been outlined in previous sections of this guide.

  1. In the main menu, go to Servers → Server Types → WebSphere Application Servers.
  2. In the list of application servers, choose the server on which you are going to deploy Business Central.
  3. Under the Server Infrastructure heading on the right, click Java and Process Management → Process Definition.

  4. Click Java Virtual Machine under the Additional Properties heading.

    This opens up the configuration properties for the JVM that is used to start WebSphere Application Server.

  5. Click Custom Properties under Additional Properties.

  6. Create the following properties by clicking New…​.

    Custom JVM Properties

    Table 3.2. Properties Required for Business Central and Realtime Decision Server

    NameValueDescription

    org.jboss.logging.provider

    jdk

    This property is only required where a CA SiteMinder TAI (SMTAI) is installed in the environment. Using this property forces Hibernate to use JDK instead of log4j for logging within Dashbuilder. CA SiteMinder TAI (SMTAI) contains an old version of log4j, which causes conflicts.

    org.apache.wink.jaxbcontextcache

    off

    This property ensures that the IBM WebSphere Apache Wink framework does not cache JAXBContexts, which negatively impacts the performance and interferes with the custom-type serialization for the REST API.

    Table 3.3. Properties Required for Business Central

    NameValueDescription

    jbpm.ut.jndi.lookup

    jta/usertransaction

    Used to look up user transactions from within non-managed threads, such as timers.

    org.uberfire.start.method

    ejb

    Defines startable beans for Uberfire.

    Set this property if following warning message appears in the logs during the deployment of business-central.war: 

    WARNING: Unable to instantiate EJB Asynchronous Bean. Falling back to Executors' CachedThreadPool
    Note

    Red Hat JBoss BRMS uses an embedded version of Git for its artifact versioning. This version of Git uses ports 9418 and 8001 for standard and SSH access (org.uberfire.nio.git.ssh.port) respectively.

    Ensure that these embedded Git ports are not already in use in your version of IBM WebSphere Application Server.

    If these ports are being used and you need to change the default Git ports, they can be changed by setting the org.uberfire.nio.git.daemon.port and org.uberfire.nio.git.ssh.port properties using the steps described above.

    For more information, see section Configuring LDAP Principal and Role Names Matching Criteria below.

    Table 3.4. Properties Required for Realtime Decision Server

    NameValueDescription

    kie.server.jms.queues.response

    jms/conn/KIE.SERVER.RESPONSE

    The JNDI name of connection factory for responses used by the Realtime Decision Server .

    org.kie.server.domain

    WSLogin

    JAAS LoginContext domain used to authenticate users when using JMS.

    org.jbpm.designer.perspective

    ruleflow

    This argument on the command line forces the default perspective in the designer to RuleFlow instead of Full.

    org.jbpm.server.ext.disabled

    true

    When set to true, disables BPM support (for example, processes support). Must be disabled for BRMS.

    org.jbpm.ui.server.ext.disabled

    true

    When set to true, disables the Intelligent Process Server UI extension. Must be disabled for BRMS.

  7. Save these configuration settings to the master configuration.
  8. Restart IBM WebSphere Application Server for these changes to take effect.

3.8. Configuring LDAP Principal and Role Names Matching Criteria

The client applications using ssh to interact with the Git server bundled with Business Central are authenticated and authorised to perform git operations using the security API offered by the Uberfire server. If your Red Hat JBoss BRMS application is deployed on WebSphere Application Server (WAS) using an LDAP security realm, the git clients may not be authorized as expected. This is because the distinguished name (DN) for the principal (user or group name) assigned by WAS is the more complex DN associated with that principal by LDAP, which leads to a mismatch of names when the Uberfire server tries to map the roles. To ensure that the role mapping does not fail, use the system property org.uberfire.ldap.regex.role_mapper to control the matching criteria of LDAP principal to role names.

The system property org.uberfire.ldap.regex.role_mapper is a regex pattern used to map LDAP principal names to application role names. Ensure that this pattern contains the variable role as it is substited by the application role name when matching a principal value to the role name. Only after the pattern is matched, the role is added to the user.

For example, if the distinguished name (DN) for the admin group in LDAP is cn=admin,ou=groups,dc=example,dc=com and the intended role is admin, then setting the following value for property org.uberfire.ldap.regex.role_mapper finds a match on admin role: 

cn[\\ ]*=[\\ ]*role

Chapter 4. Install

Now that the basic configuration is done and IBM WebSphere Application Server is set to deploy Red Hat JBoss BRMS, you can upload the WAR deployables that were extracted earlier.

As noted previously, the Red Hat JBoss BRMS ZIP file for IBM WebSphere Application Server contains the deployable WAR files for both Business Central and Realtime Decision Server.

4.1. Installing Business Central

Business Central is uploaded as a web archive and can then be accessed at http://TARGET_SERVER:PORT/business-central. Start the deployment by installing the Business Central WAR as a WebSphere application.

  1. In the main menu, go to Applications → Application Types → WebSphere Enterprise Applications.

    This will show you all the existing applications in the system and allow you to install a new one.

  2. Click Install to start the installation process.

  3. Upload the Business Central WAR file (business-central.war) from the local file system. See Section 2.2, “Extracting Red Hat JBoss BRMS for IBM WebSphere Application Server” for more information.

    Figure 4.1. Preparing for Application Installation Wizard

    install bc

  4. Click Next. This process may take some time.

    Important

    You may encounter an error message similar to the following: 

    The EAR file could be corrupt and/or incomplete. Make sure that the application is at a compatible Java(TM) Platform, Enterprise Edition (Java EE) level for the current version of WebSphere(R) Application Server.
java.lang.NullPointerException

    In that case, run ulimit -n in the command line. If the result is 1024, increase the number of open file descriptors. The recommended value is 100 000.

  5. Select the Fast Path radio button and click Next.
  6. Change the Application Name to business-central in the Select Installation Options step and click Next.
  7. In the Map Modules to Servers step, map the Business Central modules to servers according to your requirements.
  8. In the Map Virtual Hosts for Web Modules step, leave the default values and click Next.
  9. In the next step, set the context root to business-central.
  10. In the Metadata for Modules step, leave the default values and click Next.
  11. In the Summary page, click Finish to install Business Central. This process can take a while. Save the changes to the master configuration at the end of this process.

You will be returned to the WebSphere Enterprise Applications page where business-central will be listed as a new application. However, it will be stopped at this stage. Before you start the application, you need to map groups to roles, configure class loading, and enable the Bouncy Castle Crypto API.

Mapping Groups to Roles
  1. Click on the business-central application to open the application configuration page.
  2. Click Security Role to User/Group Mapping under the Detail Properties heading on the left.
  3. Select the admin role and click Map Groups…​ at the top.

  4. Search for the admin group (or just click the Search button) and move it from the Available list to the Selected list. Click OK.

    This mapping gives the previously created administrator user access to the Business Central application.

  5. Follow the same procedure for the analyst role as well and save the configuration.

If you have other groups or users that should have access to Business Central, use the same steps to map them to the admin or analyst roles.

Note

If you are also installing the Realtime Decision Server, give this user access to the kie-server role. Additionally, map appropriate REST API roles if you are going to use the REST API. For further information about API roles, see chapter Remote API of Red Hat JBoss BPM Suite Development Guide.

Class-Loading Configuration

Ensure correct class-loading configuration by following the steps below.

  1. In the main menu, go to Applications → Application Types → WebSphere Enterprise Applications.
  2. Click business-central.
  3. Click Class Loading and Update Detection under the Detail Properties heading on the left.

  4. Check the following options:

    • Class Loader Order: Classes loaded with local class loader first (parent last)
    • WAR Class Loader Policy: Single class loader for application

    Figure 4.2. Configuring Class Loading

    class loading
  5. Click OK, save the changes to the master configuration and restart the IBM WebSphere Application Server.
Enabling Bouncy Castle Crypto API

To enable Git SSH repository cloning and kie-config-cli from within Business Central, the Bouncy Castle Crypto API must be set up. Enable the API by following the steps below.

  1. Set the org.apache.sshd.registerBouncyCastle property to true and org.uberfire.domain property to WSLogin. See Section 3.7, “Adding Custom JVM Properties” for detailed instructions on how to set custom properties.

  2. Set up the Bouncy Castle API as a shared library referenced from Business Central using the appropriate version of Bouncy Castle:

    1. In the main menu on the left, navigate to Environment → Shared Libraries, select the appropriate scope and click New…​ to create a new library.

    2. Give this library a name and set the class path to the Bouncy Castle library (bcprov-jdk16-1.46.jar). Click OK and save the configuration.

      Note

      For more information about the bcprov-jdk16-1.46.jar package, see the Maven Repository — Bouncy Castle Provider page.

    3. Go to Applications → Application Types → WebSphere Enterprise Applications and click business-central.

    4. Click Shared Library References under the References heading on the left, select the web module, click on Reference Shared Libraries and move the Bouncy Castle library created in the previous step from the Available to the Selected list.

    5. Click OK and save the configuration.

You have now successfully installed Business Central on IBM WebSphere Application Server.

To start the application, go back to Applications → Application Types → WebSphere Enterprise Applications page and select the business-central checkbox before clicking Start.

To access the application, navigate to http://TARGET_SERVER:PORT/business-central in your web browser.

4.2. Installing Realtime Decision Server

The Realtime Decision Server is distributed as a web application archive file (kie-server.war) and is present in your Red Hat JBoss BRMS 6.4.0 Deployable for WebSphere 8.5 download.

Note

It is assumed that you followed the steps described in Section 3.3, “Creating Users and Groups” to create the role kie-server required by the Realtime Decision Server. If you have not done so, revisit the respective sections in this guide.

  1. In the main menu on the left, go to Applications → Application Types → WebSphere Enterprise Applications.

    This will show you all the existing applications in the system and allow you to install a new one.

  2. Click Install to start the installation process.
  3. Upload the Realtime Decision Server WAR file (kie-server.war) from the local file system.

  4. Select the Fast Path radio button and click Next.

    The Install New Application wizard opens.

  5. Change the Application Name to kie-server in the first step and click Next.
  6. In the next step, map the Realtime Decision Server modules to servers according to your requirements and click Next.
  7. In the Bind Listeners for Message-Driven Beans step, select the Activation Specification radio button for both the beans. Enter jms/activation/KIE.SERVER.EXECUTOR as Target Resource JNDI Name for the KieExecutorMDB bean, and jms/activation/KIE.SERVER.REQUEST for the KieServerMDB bean.
  8. In the next step, map resource references to actual resources. Enter the JNDI name for the KIE.SERVER.REQUEST connection factory that you created earlier: jms/conn/KIE.SERVER.REQUEST.
  9. In the Map Virtual Hosts for Web Modules step, leave the default values and click Next.
  10. In the next screen, set the context root to kie-server.
  11. In the Metadata for Modules step, leave the default values and click Next.
  12. Click Finish to install the Realtime Decision Server. Save the changes to the master configuration at the end of this process.
Class-Loading Configuration

Ensure correct class-loading configuration by following the steps below.

  1. Navigate to Applications → Application Types → WebSphere Enterprise Applications and click kie-server.
  2. Click Class Loading and Update Detection under the Detail Properties heading on the left.
  3. In the properties, change Class Loader Order to Classes loaded with local class loader first (parent last) and WAR Class Loader Policy to Single class loader for application.
  4. Save the changes to the master configuration.
Mapping Groups to Roles

If you have already mapped the kie-server role to a user or a group, you can ignore this procedure. Otherwise, do the following:

  1. Go back to the main configuration page for the newly installed kie-server application (Applications → Application Types → WebSphere Enterprise Applications). Click Security Role to User/Group Mapping under the Detail Properties heading on the left.
  2. Select the kie-server role, click Map Groups…​ and search for the kie-server group in the next screen (or just click the Search button).
  3. Move it from the Available list to the Selected list. Click OK.

This mapping gives the previously created administrator user access to the Realtime Decision Server.

You can now save the changes and start the kie-server application.

Check whether the Realtime Decision Server REST API works by sending a GET request at http://TARGET_SERVER:PORT/kie-server/services/rest/server.
