"Re: Why is Timer event not triggered in J2EE container?" To view the discussion, visit: http://community.jboss.org/message/619951#619951 -------------------------------------------------------------- Thanks for the suggestion, Mare. The transaction manager is where I'm having problem with. According to this: http://www.ibm.com/developerworks/websphere/techjournal/0609_alcott/0609_alcott.html http://www.ibm.com/developerworks/websphere/techjournal/0609_alcott/0609_alcott.html "...to ensure the integrity of transaction context management (and hence the proper management of transactional resources) *WebSphere Application Server does not expose the javax.transaction.TransactionManager interface* to applications or application frameworks deployed into WebSphere Application Server." As far as I know, both Hibernate and Spring have something of their own to work around this problem, something like : * *org.hibernate.transaction.WebSphereExtendedJTATransactionLookup* * *org.springframework.transaction.jta.WebSphereUowTransactionManager* While I do not know the how Spring and Hibernate work around on TransactionManager, I found a work-around to this problem; and it goes in 2 parts :-- 1. WebSphere does not like threads being created in EJB. The first part of the solution is to fix the threads created directly using J2SE. The class doing that is : *org.drools.time.impl.JDKTimerService. * Using the example and classes from: http://www.ibm.com/developerworks/websphere/techjournal/0606_johnson/0606_johnson.html http://www.ibm.com/developerworks/websphere/techjournal/0606_johnson/0606_johnson.html I was then able to create the thread pool using the WebSphere's WorkerManager. Now, the threads under this are under J2EE context. 2. Re-initialize the "UserTransaction" When the timer service kicks in, it tries to call the single command service class (forgot actual class at the moment). I perform a JNDI UserTransaction lookup to make it so that the drools transaction manager is new. I'll try to put a few pieces of code in here later.
