Hallo all,

this is my process definition:

I want to catch all exceptions that can be throwen during SibelTask and write the stack trace into the file.
Is it possible with boundary error event?
If yes, how can I forward with boundary error event catched error or exception to the next Java Service task?

Thanks

I think I found what I need:

transition = execution.getActivity().findOutgoingTransition("no-exception");

It isn't perfect, but at least I am able ty change a path if exception was thrown.

The problem is: I can't call getActivity() on DelegateExecution obejct.

Why it isn't available any more? How can I handle exceptions with Activity v5.3?

Thanks

Sorry for my inattention,
I found the error.

The Service Task should implemet ActivityBehavior instead of JavaDelegation
public class SiebelTask implements ActivityBehavior{
…
}

and execute(XX) with ActivityExecution instead of DeleagteExecution
public void execute(ActivityExecution execution) throws Exception {
…
}

The problem ist solved.
