Internal and External Human Task Service

houston4j Mar 4, 2013 3:33 PM

I'm new to jBPM and trying to understanding the implementation options of the Human Task Service. From my understanding I can expose the Human Task Service via a web service for external applications.

I'm wondering if I can do the following:

- Deploy/package the Human Task Service with my core jBPM project so both the Human Task Service and Process Engine run in the same JVM.

- Use the LocalHTWorkItemHandler from within my core jBPM project to interact with the Human Task Service.

- Invoke the same Human Task Service via a web service from additional external applications.

Any feedback is greatly appreciated.

Hi, In that case you need two things,
1) You can have your local task service running with LocalHTWorkItemHandler that will work fine
2) Then you need to have a task service exposed via a transport (Web Services for example) and make sure that the server is also associated with the session that is running the processes, so they can be notified if a task is completed via the Task Service that is exposed via web services.

Notice that you have 2 task services, but they share the database, so they share the state.

Cheers

Thanks for the feedback Mauricio.

Regarding point 2, this is the KnowledgeSession correct?

Yeah, Session == Ksession == StatefulKnowledgeSession -> in 6.x KieSession
