The following sections will walk through the creation, packaging, testing and deployment of the Hello World binding component.

Prerequisites

  • Maven 2.0.4 7 or higher
    • If you have never used Maven previously the Maven Getting Started Guide explains some valuable concepts surrounding Maven
  • ServiceMix 3.2.1 .2 or higher
  • A broadband internet connection so Maven can automatically download dependencies

$ mvn archetype:create \
-DarchetypeGroupId=org.apache.servicemix.tooling \
-DarchetypeArtifactId=servicemix-binding-component \
-DarchetypeVersion=3.2.1 .2 \
-DgroupId=org.apache.servicemix.samples.helloworld.bc \
-DartifactId=hello-world-bc

...

The first three parameters to the mvn command (-DarchetypeGroupId=org.apache.servicemix.tooling -DarchetypeArtifactId=servicemix-binding-component -DarchetypeVersion=3.2.1.2) identify which Maven archetype to use for the archetype:create goal, while the last two parameters (-DgroupId=org.apache.servicemix.samples.helloworld.bc -DartifactId=hello-world-bc) uniquely identify the Maven project that is being generated. The groupId is used as the Java package and the artifactId is used as the project name. Therefore, only alphanumeric characters are valid values for the groupId and artifactId parameters.

Tip

The value of the archetypeVersion parameter in the command above (3.2.1.2) may need to be updated to the current ServiceMix version in order for the command to work correctly. The latest version can always be found in the top level ServiceMix POM in the <version> element.

  • src/main/java/org/apache/servicemix/samples/bc/MyBootstrap.java - Implements javax.jbi.component.Boostrap which is called by the JBI container as part of the component lifecycle (i.e.g, when the component is installed and uninstalled). This is where you place logic to set up and tear down things when the component is started and stopped. This class is no longer needed.
  • src/main/java/org/apache/servicemix/samples/bc/MyComponent.java - Extends the DefaultComponent, a convenience class that makes creating JBI components much easier and provides some additional lifecycle management for the BC when it's deployed to the JBI container. This class should be fleshed out by overriding methods in the DefaultComponent to configure and initialize the component.
