You are right with weblogic 8, hence i am using Weblogic 9/9.2 which supports at least ejb2.1 and the EJB Timers. Is the TimerService in jbpm based on EJB3.0? I thought it's 2.1. Since the Timer functionality of JBPM is based on the J2EE Specs for EJB Timers there shouldn't be a problem to use it in compliant environments. If I check the logs, the timer is created and it's executed at the right time, but the cancelling does not work. Even the Node.leave event is fired: GraphElement : event 'node-leave' on 'State(State1: Wait 1 minute)' for 'Token(/)' Maybe it has something to do with: | Token : token[181] is locked by token[181] | ... | Token : token[181] is unlocked by token[181] Seems a little bit strange for me?!?
