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-service-unit
archetype, which is used for creating a 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 tutorial-file-su
:
mvn archetype:create -DarchetypeArtifactId=servicemix-service-unit -DarchetypeGroupId=org.apache.servicemix.tooling -DartifactId=tutorial-file-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, in which we will create our 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:
- used the groupId from the parent pom.xml for our new service unit
- added a module to the parent pom.xml
<modules> <module>tutorial-file-su</module> </modules>
Now, we will have to configure the service unit to provide the services we want.
