Ok Ronald, thanks for your clarification. Just by curiosity, my architecture is simple, what I want is a simple JBoss ESB service where there are two actions, the first action calls a JBPM process and the second action should not start before the first action fully ends (Process ends) because it depends from it and because of that is next in the pipeline and I don't want it to be executed in parallel with the first action. Do you see a way to do this? Many Thanks, Sergio View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4260600#...
