Chapter 4. Fuse Standalone

4.1. Supported containers

Fuse standalone 7.0 is supported on the following runtime containers:

  • Spring Boot (standalone)
  • Apache Karaf
  • Red Hat JBoss Enterprise Application Platform (JBoss EAP)

4.2. New features

The main new features of Fuse standalone in version 7.0 are:

  • Spring Boot standalone is now a deployment option for Fuse applications. Standalone mode is where a Spring Boot application is built as a Jar file and runs directly in a Java virtual machine (JVM).
  • Major upgrade of JBoss EAP to version 7.1.
  • Apache Camel is upgraded to version 2.21.
  • Apache Camel features the following new Enterprise Integration Patterns:

    • Claim Check EIP with push/pop functionality.
    • Saga EIP for simulating transactions in distributed systems.
  • Apache Camel supports the following new data formats:

    • camel-asn1 - the ASN.1 data format is used for file transfer with telecommunications protocols.
    • camel-fastjson - JSon data format (using the FastJSon library) is used to unmarshal a JSon payload to a POJO; or to marshal a POJO back to a JSon payload.
    • camel-thrift - the Thrift data format allows you to call and expose remote procedure calls (RPC) with the Apache Thrift data format and serialization mechanism.
  • Many more Camel components are available for Camel on JBoss EAP. There are now almost as many Camel components available for the JBoss EAP container as for the Apache Karaf container.
  • Major upgrade of Apache Karaf, from version 2.4 to version 4.x.
  • Apache Karaf supports OSGi R6 (upgraded from OSGi R5).
  • Apache Karaf is now configured to use the Narayana transaction manager (replacing the Geronimo transaction manager used in Fuse 6.x).
  • Apache Karaf now supports the Undertow servlet container.
  • Apache Karaf has a new features resolver, which simplifies feature installation and lifecycle. The new resolver checks the feature requirements (defined directly in the features XML), and checks which bundles provide the capabilities to satisfy those requirements. It enables Karaf to install bundles required by features automatically.
  • Client-side integration with AMQ 7 (based on ActiveMQ Artemis) is supported in Fuse 7.0. For more details, see the Supported Configurations page.
  • Web tooling has been upgraded to the PatternFly look and feel.
  • The following Apache Camel components are new in Fuse 7.0:

    • camel-atomix - a component to integrate Camel with Atomix
    • camel-aws - KMS component for managing Amazon KMS
    • camel-aws - MQ component for working with Amazon MQ

    • camel-crypto-cms - a component for cryptographic message syntax
    • camel-digitalocean - The digitalocean component allows you to interact with the Digitalocean cloud
    • camel-drill - The drill component gives you the ability to querying to Apache Drill Cluster

4.3. Important notes

Important notes for the Fuse 7.0 release of the Fuse standalone distribution:

Fuse Console (Hawtio) is not remotely accessible by default
In Fuse 7.0, remote access to the Fuse Console is restricted by a Cross-Origin Resource Sharing (CORS) whitelist. By default, the Fuse Console can only be accessed from the local host. To open up access from remote hosts, you need to add hostnames to the CORS whitelist. For more details, see Managing Fuse.
Some Karaf-related components have been removed in 7.0
As part of the consolidation and refactoring of Fuse, a number of components related to the Apache Karaf container have been removed in version 7.0. For more details, see Chapter 5, Deprecated and Removed Features.
