Does anyone know if there is a way to filter with a QueueBrowser using a range of priorities?
You can say something like QueueBrowser qb = qSession.createQueueBrowser(queue, "JMSPriority = 1");
Is there a way to get all, say 1-5 priority messages?
Just trying to find a way so I dont have to traverse the queue 5 times. Also didnt want to have to return all messages and have to go through the entire enumeration. |

If you tell the queue to return messages in priority order, then you can browse and stop when the priority of the message is less than what you want.

Thanks Jeff,
Figured that was the only way, thought maybe there would be a faster way. |

Using any JMS filters is slower than not using any.

Jeff thanks, you are right.
But just for completeness wanted to record that I did find a way to filter based on range.
QueueBrowser qb = qSession.createQueueBrowser(queue, "JMSPriority > 0 AND JMSPriority < 6"); |
