Get size of queue
Hi all,
is it somehow possible to get the exact number of items in a queue
with the jms api ? It would be also nice to be able to check the size
of items with a given selector..
So any idea?
Thx,
Norman

Hi Bruce,
we used the camel activemq component and use a selector, which works
without probs.. So thats not the problem ;)
Thx,
Norman

You could implement a delay feature with ActiveMQ by using Camel's
timer component.

Hi Bruce,
we use ActiveMQ for storing our outgoing emails in JAMES
(james.apache.org). The emails are consumed via a JMS Selector on a
given time (for retry after temporary error). This will prolly be
changed once ActiveMQ 5.4 was released with its delay feature ;)
Now we want to give the administrator some kind of feedback how many
emails are in the queue etc.
Bye,
Norman

APIs are available for this via JMX. However, that number is only good
for that exact second in time. This is just the nature of JMS because
messages are flowing through the system constantly. Why do you need
the queue size?
