That is an interesting suggestion. Do you see any downside to having 2 ProcessEngines running? (1 on Tomcat and 1 on JBoss) The only thing I can think of that would be an issue is communicating with external systems. By having multiple ProcessEngines it starts to complicate the architecture. But not that much really. Thanks Jim View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252841#...
