I wrote the following logic using JMSMessageListener:

In the main class,
1) get connection, get session (call it theSession)
2) get an instance of a class (call it MyListener) that implements JMSMessageListener by
MyListener theListener = new MyListener(theSession);
Notice theSession is passed onto theListener
3) get a receiver from theSession
4) register theListener to the receiver

Now in the onMessage() method of MyListener class,
5) get a text message
6) get the reply queue that comes along with the message
7) create a sender from theSession (the same one from 1) above)
Finally call the send method from the sender to dispatch a reply message

I have two questions:
i) does the above logic violates the session/thread safe guard? I did a small test without much volume, it seems to work fine.
ii) if I create more similar receivers for the same queue in the main class, will it improve the throughput?
