In the following example, two queue are created, and the sender sends a message to one queue. After receiving the message, the receiver replies a message to the other queue, then create a consumer to receive the reply message.

First, the message producer sends a message with the content of "Andy". Then, after receiving the message, the consumer replies a message with the content of "Hello Andy" based on the message's jmsreplyto '. Finally, create a consumer in the reply queue to receive the reply message, and output the reply content.
Run the above program to get the following output:
