Process Event listener : not able to register

[rdeveloper87]

Hi,

I am adding a process event listener to a process as follows:

public KieSession createKnowledgeSession(

  String processName) {

  KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

  kbuilder.add(ResourceFactory.newClassPathResource(processName), ResourceType.BPMN2);

  KnowledgeBase kbase = kbuilder.newKnowledgeBase();

  StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

  ksession.addEventListener(new SampleProcessEventListener());

  return ksession;

  }

When i put my flow in debug mode , i do not traverse the afterProcessStarted method.

Am i missing something while doing this.

TIA

Hi!

You must to create a class that implements EventListenerProducer<ProcessEventListener> and anotate it with @Process like this:

@Process
public class ProcessEventProducer implements EventListenerProducer<ProcessEventListener> {

  @Inject
  private YourProcessEventListener listener;

  @Override
  public List<ProcessEventListener> getEventListeners(String identifier,  Map<String, Object> params) {
   List<ProcessEventListener> list = new ArrayList<ProcessEventListener>();
   list.add(listener);
   return list;
  }
}

And you must to use a InjectableRegisterableItemsFactory in your RuntimeEnvironmentBuilder

Hope it helps!
