jbpm6 custom ProcessEventListener

[whitakersp]

So I'm trying to create an event listener in jBPM6, running on eap 6, and I've created a class that implements ProcessEventListener.

Right now all I'm doing is system outs for testing.  I deployed the jar into business-central.war/WEB-INF/lib.  With the same permissions as the rest of the jars in there.

In the BPM Suite project authoring I edited the session to have a process event listener to point it at my class com.test.jbpm.TeamStrikeProcessEventListener.

When I hit build & deploy

I'm getting

java.lang.ClassNotFoundException: com.test.jbpm.TeamStrikeProcessEventListener from [Module "org.drools:main" from local module loader @54031f94 (finder: local module finder @190e58a3 (roots: /test/apps/jboss/jboss-eap-6.1/modules,/test/apps/jboss/jboss-eap-6.1/modules/system/layers/bpms,/test/apps/jboss/jboss-eap-6.1/modules/system/layers/base))]

If its in the lib directory why is it not being found.  Do I need to create a module in jboss just to have a custom class?  I don't want to reuse this jar outside of jbpm.

Your help would be appreciated.

Thanks

Well I added my jar as a dependency to org.drools to get it to see my implementation.  Now I've ran into another error.

Not sure about this one.  My class implements ProcessEventListener, and now it is finding it.

:/

Same issue , there is little doc to describe it .

Hi,

I had recently similar issue. The thing is, that the container can't find a bean of given type. My solution was to implement a producer method.

In your case sth similar to:

<code>

import com.test.jbpm.TeamStrikeProcessEventListener;

public class ListenerProducer {

     @Produces

     public TeamStrikeProcessEventListener getListener(){

          return new TeamStrikeProcessEventListener();

     }

}
