Does JMS have a concept of a queue peek?


From a general Computer Science perspective - when we think of a Queue in a logical sense - we think of being able to 'peek' the first item in the queue.

When I look at the JMS API - it has a MessageListener - which has an OnMessage() method. This feels a little bit like "don't call us- we'll call you."

Solution

  • 1) If you want to receive messages synchroneously use MessageConsumer.receive

    2) Basically, 'peek' in queues means to return, but do not remove, the head of the queue. For this you can use QueueBrowser to look at messages on a queue without removing them.
