Unable to create a transacted JMS Session

Question

          We have some code that worked perfectly under wls7.0 and earlier, but refuses to
          work under wls8.1. In our situation, we are unable to create a JMS Session with
          internal transactions.
          The result of the following code
          System.out.println("transacted_=" + transacted_);
          tsession=tcon.createTopicSession(transacted_, Session.AUTO_ACKNOWLEDGE);
          System.out.println("session.getTransacted()=" + tsession.getTransacted());
          is the following
          transacted_=true
          session.getTransacted()=false
          We have tried using xa true and false; but commonly use false.
          //from config.xml
          <JMSConnectionFactory JNDIName="corej2ee.jms.JMSConnectionFactory"
          Name="CoreJMSConnectionFactory" Targets="myserver"/>
          thanks,
          jim
          

Answer 1

An alternative is to modify the servlet code to use global (user)
          transactions instead of local (transacted session)
          transactions - the performance will likely be the same in your case -
          or may actually improve due to the activation of the pooling code.
