MQSeries.net :: View topic - Request Response .... architecture using JMS

Trying to have an acknowledgement after putting the message on the MQSeries Server using MQSeries Client(MA88 only).
I used the QueueRequester class and used the request method of it. The message is placed successfully on a queue as given in the constructor of QueueRequester but when I tried to respond back from the server side using the temporary queue ( created by the .... tempQueue = (Queue) message.getJMSReplyTo(); ) and tried to create the QueueSender using this queue it started giving me the exception reason code .. 2085..
The crux is I am unable to get the queueSender...

The point to be noted here is I am trying to access a queue which is temporary one created by the QueueRequester class.When I get a System.out.print of that temp. Queue , I get it as good as any object.
By the help of this queue when I try to create the queue sender ,I get an Exception.

code in brief :-

I made two threads .. one for Request and one for Reply.....

in first thread :

TextMessage reply = (TextMessage) queueRequestor.request(message); // now this thread will hang till it gets the response from the server..

in second thread:

queueReceiver = queueSession.createReceiver(queue);
queueConnection.start();
message = (TextMessage) queueReceiver.receive();
message.setJMSDeliveryMode(DeliveryMode.NON_PERSISTENT);// temp R&D

System.out.println("REPLY: Message received: "
+ message.getText());
Queue tempQueue = message.getJMSReplyTo();
reply = queueSession.createTextMessage();
reply.setJMSDeliveryMode(DeliveryMode.NON_PERSISTENT);
reply.setText(REPLY_TEXT);
reply.setJMSCorrelationID(message.getJMSMessageID());
System.out.println("REPLY: Sending reply: " + reply.getText());

System.out.println("Here is the error"); // this reply sender below is not being created...
replySender = (com.ibm.mq.jms.MQQueueSender)queueSession.createSender(tempQueue);
replySender.send(tempQueue,reply);
