Forcing processing of a queue and wait until empty

[micha <mi...@ww-informatik.de>]

Hi all,

we have switched to activemq and we are using automated webtests. Some of
these tests put messages in a queue and we have to wait for these messages
to be processed before we can go on with the tests.

Messages gets redelivered on failures. Currently I use jmx in a loop with a
sleep and assume that it failed if the queue not gets empty within a period
of time.

Now the question is if there exists a better way. Such as a way to force the
processing of a queue (and gets information if the processing has failed) in
order to speed up the tests?

Regards

Michael

if you set the expiry on the messages you can assume that all messages
will be "processed" one way or the other by the expiry time.

if you have the web interface enabled you can fetch the queues page
and parse that in a shell script, it will be faster and less resource
consuming than firing up a JVM for each peek in the queue.

only consumers can "force the processing" by consuming, ActiveMQ can't
force the consumers to do anything, how would it, anyway?
