Message queues

As we mentioned earlier, Message queues are used when our JMS code uses the Point-To-Point (PTP) Messaging Domain.

The message producer and the message consumer don't need to be running concurrently in order to communicate. The messages placed in the message queue by the message producer will stay in the message queue until the message consumer executes and requests the messages from the queue.
