Deploy BPMN Model from bundled JAR archive

Dear all,

I have following structure in my WAR archive:

|-- my-app.war
    |-- WEB-INF
	    |-- classes
    	    |-- META-INF/processes.xml
	        |-- process.bpmn
		|-- lib
		    |-- customer.jar
	            |-- customer-process.bpmn

and this is my ProcessApplication class:

@Singleton
@Startup
@ConcurrencyManagement(ConcurrencyManagementType.BEAN)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@ProcessApplication("MyBpmProcessStarter")
@Local(ProcessApplicationInterface.class)
public class LuminBpmProcessStarter extends EjbProcessApplication {

    @PostConstruct
    public void start() {
        deploy();
    }

    @PostDeploy
    public void onPostDeploy(ProcessApplicationInfo processApplicationInfo,
                             ProcessEngine defaultProcessEngine,
                             List<ProcessEngine> processEngines) {
        logger.infof("injected '%d' processEngines", processEngines.size());
        // ->  injected '4' processEngines ???
    }
}

When calling deploy() in my ProcessApplication class the process.bpmn will automatically be deployed, because in processes.xml i have <property name="isScanForProcessDefinitions">true</property>

Additionally I have a customer.jar bundled with my-app.war also containing a BPMN Model.

So the question is: how do I get the customer-process.bpmn also automatically be deployed? Do I have to set the resourceRootPath in the processes.xml accordingly and how?
And why are there more than 1 process engines injected in onPostDeploy() method?

Thanks and regards,
Rainer

Adding a processes.xml to the META-INF folder of my customer.jar solved the autodeployment issue!

The deployment structure now looks like this:

|-- my-app.war
    |-- WEB-INF
	    |-- classes
    	    |-- META-INF/processes.xml
	        |-- process.bpmn
		|-- lib
		    |-- customer.jar
         	    |-- META-INF/processes.xml
	            |-- customer-process.bpmn
