How and where ca I turn this on? I noticed something very interesing so: I used "(a)TransactionAttribute(TransactionAttributeType.NEVER)" on the first call to the SLSB (stateless) and the transaction gets stopped! In the logfile I see: 007-05-04 14:56:08,090 ERROR [org.jboss.ejb.txtimer.TimerImpl] Error invoking ejbTimeout: javax.ejb.EJBException: java.lang.IllegalStateException: Transaction present on server in Never call However, if I place the annotation on the method, which actually creates a single entity and gets called by, then nothing happens. So this explains why placing @TransactionAttribute(REQUIRES_NEW) on it does not work either! The big question now is why? Do you have idea? Here once more the flow of execution: 1. User clicks button 2. userSchedule() gets called on SFSB1 3. scheduleMessages() gets called on SLSB1 by SFSB1 4. scheduleMessage() gets called by SLSB1 many times Placing "(a)TransactionAttribute(TransactionAttributeType.NEVER)" on scheduleMessages() stops the flow of execution. However, placing it on scheduleMessage() has no effect!! Why is that? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043164#...
