Note: The content of this document is overlapping with Notes on Creating JBI Component using maven2 and Hello World - BC and Hello World - SE. Any changes you might want to do for this document might be relevant for them as well. Questions unanswered by this document may be answered by the other documents.

This document is a tutorial that describes the steps involved in the creation of a standard JBI Component using servicemix-common module.
We will write a full XSLT Service Engine.

First, we will use the servicemix-service-engine maven 2 archetype to create the basis of our JBI component.

Using the maven2 archetype

Run the following command (remove the trailing backshlashes and make it one line):

Code Block

mvn archetype:create \
        -DarchetypeGroupId=org.apache.servicemix.tooling \
        -DarchetypeArtifactId=servicemix-service-engine \
        -DarchetypeVersion=3.0-incubating \
        -DgroupId=org.apache.servicemix.xslt \
        -DartifactId=servicemix-xslt

The first three parameters identify the maven 2 archetype to use, while the last two parameters are used for the generated maven 2 project. The version information "3.0-incubating" may have to be changed; just look at any of ServiceMix' pom.xml for the version you are using.

While ServiceMix is in the incubator you have to specify the incubator repository in order to use the servicemix maven 2 archetypes, unless you did not include the repository in your local maven configuration.

Code Block

        -DremoteRepositories=http://people.apache.org/repo/m2-incubating-repository

This will create the following files:

Code Block

servicemix-xslt\
  pom.xml
  src\
    main\
      java\
        org\
          apache\
            servicemix\
              xslt\
                MyBootstrap.java
                MyComponent.java
                MyDeployer.java
                MyEndpoint.java
                MyLifeCycle.java
                MySpringComponent.java
    test\
      java\
        org\
          apache\
            servicemix\
              xslt\
                MySpringComponentTest.java
      resources\
        spring.xml

Testing the generated component

The default implementation of the component accepts InOut MEPs and return the input content as the out message.

To test it, just run

Code Block

mvn test

You should see something like:
