AQ-JMS-WLS

Question

          Hi,
          I am binding the a AQJMS_FACTORY & a AQ_QUESUS to the JNDI tree of WLS using a
          startup class and polling on the queue using an MDB. (I have used Eric Ma's code
          as an example.)
          But, the problem is that MDB polls on the queue only "during" starting of WLS
          or when the MDB is being re-deployed. After, starting WLS the MDB fails to read
          messages from the AQ unless redeployed. I have checked the JNDI tree using WLS
          console. The AQJMS_FACTORY & AQ_QUESUS are bound to the tree correctly. The polling
          interval of the MDB is set to 1 sec.
          Can anyone give pointers to why the MDB is not polling on the AQ ?
          Problem I realized is that the either DB connection or QSession is not live
          to get the Queue.
          Every time MDB poll the Queue it is looking for DB connection.
          Can any one help me to keep both the connection live by any mean on Webligic server?
          Regards,
          Jugal
          

Answer 1

          Tried it again on another Unix server, it worked.
          Thanks,
