Spring MDP not Consuming Message - spring

Question

I am implementing Spring MDP + JMSTemplate to send and receive the message. The message send mechanism is working fine, however the MDP is not getting invoked. I tried testing the via plain receiver, and was able to retrieve the message, but not via MDP. What could be the problem? I can see the messages getting accumulated in the request queue, but somehow the MDP is not getting trigger. Am I missing anything here in configurations or something else needs to be taken care of?
Here's the Spring Config. The Java class to send and received are pretty much standard ones.
