    user transaction problem

    Manfred Meyer Newbie

      I have problems with user transactions in servlets. I want to make some database entries and send a JMS message as an atomic piece of work, protected by a user transaction. While the database resource is committing and rollbacking correctly, the JMS message is not committed by the transaction manager. Is JBoss 3.0.4/Jetty ready for doing something like this or what am I doing wrong. Unfortunately using a session facade is not an option because I have to process SOAP messages with attachments in the transaction.

      Here are fragments of the code:

      try {
      ut = (UserTransaction)initContext.lookup("java:comp/UserTransaction");
      qcf = (QueueConnectionFactory)initContext.lookup("java:comp/env/jms/QueueConnectionFactory");
      // using XAConnectionFactory
      conn = qcf.createQueueConnection();
      conn.start();
      session = conn.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);
      jobReceiverQueue = (Queue)initContext.lookup("java:comp/env/jms/queue/jobreceiver");
      sender = session.createSender(jobReceiverQueue);

      ut.begin();
      // doing some databases updates
      // creating a jms message

      sender.send(jmsmsg);
      ut.commit();
      } catch (Exception ex) {
      ut.rollback();
      // ...
      } finally {
      sender.close();
      session.close();
      conn.stop();
      conn.close();
      }

      Thanks,
      Manfred
