BEA Weblogic Interview Question:

How does sorting on message priority work?

Submitted by: Administrator

First, you need to add a key to the destination (by default, they are not sorted), choosing JMSPriority as the key. If you want 0 to be your highest priority, make the key ascending. If you want 9 to be the highest priority, make the key descending.
Second, the priority must be set using either the producer or on the send, not the message.
Third, the priority sorting only comes into play if there are multiple messages waiting on the queue. If the receiver is always caught up with the sender, then the messages will be processed in the order in which they come in.
