[jboss-user] [JBoss jBPM] - how to integrate a long external task that may fail and noti

[wyckoff]

My workflow is composed of non-java (perl) tasks which are long running and may fail and would send notification of success or failure asyncronously.

I want to know the best way to 

a) call out to the service and then enter a wait state
b) recieve a notification from the service on success/failure (JMS?)
c) retry the task on a timeout

The main results of the task are actually written to a netapp so data isn't an issue (and of course the results are written idempotently so retry isn't a problem).

I'm new to J2EE/JBOSS. 

Thanks, pete
