Thanks for the quick response. I was under the impression I needed JCA for transactional JMS. I've removed the tx-connection-factory and now the code snippet I posted works. However.. I now get an error like this: | 2009-04-30 19:15:11,619 ERROR [org.jboss.messaging.util.ExceptionUtil] ConnectionEndpoint[h3-67tn85uf-1-hjjm85uf-wxb1yo-f1rp1a] sendTransaction [w7-rezp85uf-1-hjjm85uf-wxb1yo-f1rp1a] | javax.jms.IllegalStateException: Cannot find session with id r7-lczp85uf-1-hjjm85uf-wxb1yo-f1rp1a | at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.processTransaction(ServerConnectionEndpoint.java:835) | at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.sendTransaction(ServerConnectionEndpoint.java:497) | | ..stacktrace snipped... | 2009-04-30 19:15:11,619 WARN [com.arjuna.ats.jta.logging.loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.preparefailed] [com.arjuna.ats.internal.jta.resources.arjunacore.preparefailed] XAResourceRecord.prepare - prepare failed with exception XAException.XA_RETRY | 2009-04-30 19:15:11,619 WARN [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_50] - Prepare phase of action a3d1b33:c3e:49f96bb1:6f received heuristic decision: TwoPhaseOutcome.HEURISTIC_HAZARD | 2009-04-30 19:15:11,619 WARN [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_36] - BasicAction.End() - prepare phase of action-id a3d1b33:c3e:49f96bb1:6f failed. | 2009-04-30 19:15:11,619 WARN [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_37] - Received heuristic: TwoPhaseOutcome.HEURISTIC_HAZARD . | Is this still a JMS problem or should I be asking in the JTA forum?
