<div class="jive-rendered-content"><blockquote class="jive-quote"><p>I am not using async job execution, I have wait states, waiting for a reply from a service. "some obvious stuff like rollback of the ongoing transaction" - how will the transaction rollback if the application shutsdown gracefully or crashes.</p></blockquote><p>When your execution reaches the wait state the transaction is committed, there is no need to rollback just because of a shutdown, after bootup jBPM4 picks up your wait state and still waits for a signal, maybe I miss the point here but I don't see a reason to rollback because of a graceful shutdown? In case of a crash the normal transaction handling in your database or on the jdbc or hibernate level rolls back the changes, just like in any other database application.</p><blockquote class="jive-quote">Retry-Interceptor : - could you please provide more insight on this. any pointers on how to make best use of them and when should we use them.</blockquote><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>the retry-interceptor is what you configure in your command service, see the dev guide (6.7 Services):</p><p><a class="jive-link-external-small" href="http://docs.jboss.com/jbpm/v4/devguide/html_single/" target="_blank">http://docs.jboss.com/jbpm/v4/devguide/html_single/</a></p><p>it's ment for catching hibernate StaleObjectExceptions but I still get those Exceptions so it seems like it doesn't work in all cases...</p></div>
