[jbpm-users] [JBoss jBPM] - Weird Jbpm exception.. need help...

Has anyone ever met such exception while doing jbpm integration with struts and spring. I'm very confused. I connect a decision node to a state node and then next an End state. The process goes all the way down to that state node. But when I try to signal that state by coding processInstance.signal(), this exception pop up... java.lang.ClassCastException: org.jbpm.msg.jms.JmsMessageServiceFactory cannot be cast to org.jbpm.svc.ServiceFactory It's a Http status 500 page... The server console says: 00:16:33,859 ERROR [CachedConnectionValve] Application error: default did not complete its transaction This signal exception always happen when the next node is an End state... Please help me. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4224996#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
