doubt in receiving a message from queue

[pavi]

Actually in my project i send a file to queue and the other server receives that file from queue and process it and then put the processed file in the same queue and i receive the processed file from that queue.

java program will always be listening to the queue for any new message.

now the problem is that i receive the same file which i sent.so in this case how to receive the reply file alone from queue.
