MQ series is an IBM product for middleware. MQ has runtime objects like Queue Managers and Queues. Queue Managers manage lots of objects like Queues, channels etc. Queue is an object that holds messages in any format - XML or text or byte.You can send message from one queue on one queue manager to another queue on another queue manager using channels. Listener applications listen on these queues to grab the messages and then process these messages.JMS is a standard provided by J2EE specification for asynchronous messaging. You can define Queues or topics in your J2EE container and then send messages on these queues using java program or any program.You can configure MDBs to listen on these JMS queues. Once a message is on the JMS queue , the corresponding MDB's onMessage method gets kicked off and you can do your message processing
