[jboss-user] [Messaging, JMS & JBossMQ] - MDB - MQ concurrency

[rajasekharreddym@gmail.com]

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 .
