To view the discussion, visit: http://community.jboss.org/message/619645#619645 -------------------------------------------------------------- Yes, sorry I've stripped too much from my code.  It's updated. The exception comes after 3 minutes when the timer kicks in.  This line suggests that the timer is triggered: at org.drools.persistence.jpa.JpaJDKTimerService$JpaJDKCallableJob.call(JpaJDKTimerService.java:75) However, I suspect that Websphere's cannot find the transaction/ context for it?  Is there anything to do with the EJB starting its own threads (by Drools) ?  com.ibm.ejs.container.EJSContainer.processTxContextChange Thanks for the suggestion Mare. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/619645#619645] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
