Creating the http consumer SU

Now, we are going to create our first SU module in our project.

Using a Maven archetype to create the service unit project

ServiceMix provides several Maven archetypes to help you create your projects more rapidly and reliably.
We start off by using the servicemix-http-consumer-service-unit archetype, which is used for creating a http consumer service unit project. The groupId for this archetype is org.apache.servicemix.tooling.

From our tutorial project directory, where we already have the parent pom.xml, we run this command to create a service unit project named http-consumer-su:

mvn archetype:create \
  -DarchetypeGroupId=org.apache.servicemix.tooling \
  -DarchetypeArtifactId=servicemix-http-consumer-service-unit \
  -DgroupId=org.apache.servicemix.examples \
  -DartifactId=http-consumer-su

Maven executes the archetype and reports BUILD SUCCESSFUL when it's done.

What is being generated?

First of all, the archetype creates the project directory, containing:

  • a pom.xml file for building the service unit project
  • a directory src/main/resources containing a template xbean.xml file for configuring the service unit

Because we started Maven's archetype:create from the directory containing our parent pom.xml, Maven has also added a module to the parent pom.xml

...
<modules>
    <module>http-consumer-su</module>
</modules>
...

Now, we will have to configure the service unit to provide the services we want.
