JMS Session and Container Managed Tx

Question

          Hello,
          We have encountered the following problem:
          1) A Transaction was initiaited by the Container on EJB1.a() ("Required"-in CMT)
          2) a topic jms session was initiated by: cSession = connection.createTopicSession(
          false, TopicSession.AUTO_ACKNOWLEDGE );
          3) When I rollback the tx, all but the jms sendings roolback. Meaning the jms
          session was not a part of the tx.
          How do I relate between a jms session and a container transaction. Do I necessarily
          have to use user transaction to solve this problem?
          Many thanks in advance,

          This is 100% wrong. Making a session transacted specifically causes JMS
          to ignore any existing transaction in favor the session's internal transaction,
          as required by the JMS specification. You need to use a connection
          that specifically checks for JTA (user) transactions. Either use an
          XAConnection
          or use a connection factory with the "user transactions enabled" flag set.
          There are number of transaction
          questions answered in the FAQ, they should point you in the right
          direction:
          http://e-docs.bea.com/wls/docs61/faq/jms.html
          The JMS programmer's guide also has this information.
