Robbie Gemmell commented on QPIDJMS-86:
---------------------------------------
I'd suggest you try the current 5.12 snapshots to see how it behaves, and then
raise the issue over at ActiveMQ if you are still having problems, as this
seems like a configuration or broker issue. The client is giving the broker
credit to send messages and the broker isn't using it, likely because of the
broker-side configuration you are setting.

> My broker's default prefetch policy is set to 0 (using ActiveMQ).
> When my queue consumer connects to the broker, the broker reports that the
> consumer has indeed a prefetch of 0.
> The qpid client however, just uses the defaults defined in the
> JmsPrefetchPolicy class (ergo, 1000 for the queue).
> So when the qpid client tries to decide whether it needs to poll or not in
> JmsMessageConsumer...
> {noformat}
> protected void sendPullCommand(long timeout) throws JMSException {
> if (messageQueue.isEmpty() && (getPrefetchSize() == 0 ||
> isBrowser())) {
> connection.pull(getConsumerId(), timeout);
> }
> }
> {noformat}
> ... the if condition will be false, since the prefetch size returned here is
> 1000. Qpid will therefore not poll and the broker not push either, resulting
> in no messages processed.
> My current workaround is that I have to set the prefetch size on the client
> as well.
