JMS interview questions

!!! JMS interview questions !!!Q. When to Remove messages from the queue ?When an application uses ConnectionConsumers, JMS might need to remove messages from the queue in a number of situations: 1) Badly formatted message A message might arrive that JMS cannot parse. 2) Poison message A message might reach the backout threshold, but the ConnectionConsumer fails to requeue it on the backout queue. 3)No interested ConnectionConsumer For point-to-point messaging, when the QueueConnectionFactory is set so that it does not retain unwanted messages, a message arrives that is unwanted by any of the ConnectionConsumers. |
