I tried using latest 3.0.3 snapshot (from Jan 27) - same problem. I am using resin. Here is the code (cleanup a bit for readability) from the class UserMangerImpl: UserTransaction utx= null; Context context = new InitialContext(); utx = (UserTransaction) context.lookup("java:comp/UserTransaction"); logger.info("user TX before start of TX: "+utx+", status: "+utx.getStatus()); utx.begin(); logger.info("started user TX: "+utx+", status: "+utx.getStatus()); try { //update cache here //update db here //throw dummy exception here throw new RuntimeException("test"); logger.info("committing tx"); utx.commit(); } catch (Exception e) { logger.info("rolling back tx"); utx.rollback(); } logger.info("User TX:"+utx+", status: "+utx.getStatus()); Here is relevant output (app output removed): 14:58:33,461 [http--8080-0$20568209] INFO UserManagerImpl:updateUser:58 - user TX before start of TX: UserTransactionProxy[], status: 6 14:58:33,463 [http--8080-0$20568209] INFO UserManagerImpl:updateUser:63 - started user TX: UserTransactionProxy[], status: 0 14:58:33,463 [http--8080-0$20568209] DEBUG NearCacheImpl:setValue:53 - setting value for object:/user/1:86 in cacheId:3 14:58:33,465 [http--8080-0$20568209] INFO TMCacheListener:onNodeTransactionregistered:29 - : EventImpl{type=TRANSACTION_REGISTERED,pre=false, cache=org.jboss.cache.DataContainerImpl [2 nodes, 0 locks], modificationType=null, data=null, fqn=null, transaction=Transaction[01:730c2f36], originLocal=true, targetFqn=null, successful=false, newView=null, buddyGroup=null} 14:58:33,476 [http--8080-0$20568209] INFO TMCacheListener:onNodeEvent:41 - : EventImpl{type=NODE_MODIFIED,pre=true, cache=org.jboss.cache.DataContainerImpl [2 nodes, 0 locks], modificationType=PUT_DATA, data={d=TMUserImpl{_id=1:86, _username='asdf', _SLUsername='', _password='sdf{salt}', _email='asdf(a)xomc.om233', _userStateCd=A}}, fqn=/user/1:86, transaction=Transaction[01:730c2f36], originLocal=true, targetFqn=null, successful=false, newView=null, buddyGroup=null} 14:58:33,492 [http--8080-0$20568209] INFO TMCacheListener:onNodeEvent:41 - : EventImpl{type=NODE_MODIFIED,pre=false, cache=org.jboss.cache.DataContainerImpl [2 nodes, 0 locks], modificationType=PUT_DATA, data={d=TMUserImpl{_id=1:86, _username='asdf', _SLUsername='', _password='sdf{salt}', _email='asdf(a)xomc.om233', _userStateCd=A}}, fqn=/user/1:86, transaction=Transaction[01:730c2f36], originLocal=true, targetFqn=null, successful=false, newView=null, buddyGroup=null} 14:58:33,572 [http--8080-0$20568209] INFO UserManagerImpl:updateUser:95 - rolling back tx 14:58:33,574 [http--8080-0$20568209] INFO TMCacheListener:onNodeTransactioncompleted:24 - : EventImpl{type=TRANSACTION_COMPLETED,pre=false, cache=org.jboss.cache.DataContainerImpl [2 nodes, 0 locks], modificationType=null, data=null, fqn=null, transaction=Transaction[], originLocal=true, targetFqn=null, successful=false, newView=null, buddyGroup=null} 14:58:33,612 [http--8080-0$20568209] INFO UserManagerImpl:updateUser:103 - User TX: UserTransactionProxy[], status: 6 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4206063#...
