One of the things that you'll need to explore is if jBPM BPEL can be deployed with jBPM JPDL in the same environment. That might be your related to problem. The ESB 4.2 bundles in jBPM JPDL 3.2.1 already which makes for a very, very nice simple orchestration solution where the service endpoints don't have to have WSDLs. I don't know of anyone trying to integrate jBPM BPEL with the JBoss ESB. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074558#...
