    MDB - MQ concurrency

    rajasekhar reddy Newbie

      i'm using jboss4.2 , running and MDB (Message Driven Bean) specifially message-inflow-driven-bean

      i have IBM MQ .

      i have configured bridge between MQ and MDB running in JBOSS using MQ resource adapter on JBoss .

      i have followed this link for configuring http://www.ibm.com/developerworks/websphere/library/techarticles/0710_ritchie/0710_ritchie.html


      i'm able to recive messages at MDB from MQ asynchronously and it is working fine .

      By default MDB exhibits concurrency .

      now my requirement is , i need to control the number of MDB istances , i want single instance read the messages .


      i have tried by editing standard jboss.xml at container configuration message-inflow-driven-bean at the max instances tag ,

      as

      <container-pool-conf>
      1
      1
      </container-pool-conf>

      still it is exhibiting concurrency .

      then i have trail with standard MDB container config setting ,i made them as

      <container-pool-conf>
      1
      1
      </container-pool-conf>


      still my MDB is exhibiting concurrency .

      how can i control number of instances of my MDB .
