I am writing a JMS program using two queue Req and Res. Can someone share me the code for correlating the request message with the response message using the correlation id. I am anticipating 25 concurrent process. This would be java multithreading prog and I do not want to mess request message with the response message

Thanks

There are sections of the Programming Guide that tell you how to do this.

You can use the correlation identifier in any way that you like. However, an intended use of this field is for applications to copy the message identifier of a request message into the CorrelId field of a reply message.

And remember, if you want performance your selector had better reference the correlId in its provider form: 'Id:xxxxxxxxxxxxxxxx' where xx is a hex representation of a byte value.
