Hi Bernd, yes, of course, obviously this was still somehow not clear to me. I just tested it and it works as well. So, you "only" need to set the esbToBpmVars-Mapping in the processdefiniton.xml and afterwards take care about that this mapping is also copied from replyTo() to To() in the Call object of the message header. Thanks again! Andre View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4237671#...
