Java Service Tasks - Java exceptions

[ruedesilva]

Hi,

In a Java service task I am calling EJBs in a different system. When exceptions are thrown from the EJB how do I throw an exception in the service task (JavaDelegate) so that the exception can be translated to a BoundaryErrorEvent so that a proper path can be followed in the WF ? Or do I need to catch exceptions within the service task set some Process variables and use exclusive gateway to take different paths for different exceptions?

thanks,
Rue

you can't throw an error event IN a service task and catch it on the same service task. You can do that with call activities (see http://www.activiti.org/userguide/index.html#bpmnBoundaryEvent)

Java execptions should be handled IN the service task and result in a logical bpmn outcome as indeed e.g. setting a variable and use that later on. So yes, you can (should) do it the way you describe.
