I have some code about ConnectionConsumer that works fine with J2EE JMS.
When I tested them with iMQ, I got following "Resource in conflict" error
message. If I run some other examples without ConnectionConsumer, they work
fine. Therefore, I like to know if iMQ support ConnectionConsumer? And do
you have any sample code that I can follow? Is there any trick for running
ConnectionConsumer?
iMQ does support ConnectionConsumer. However, you do need to ensure that if
you are consuming messages from a Queue, then the physical queue
destination's queue delivery policy needs to be configured as "round
robin", rather than "single" (which is the default).
The exception you got is a result of attempting to attach two receivers on
a physical queue that is configured for only one receiver (at a time).
You can do this by running the following JMQ Command when creating the
physical queue or the next command to update the property for an existing
physical queue.
Physcial queue creation
jmqcmd create dst -n <name_of_queue> -t q -o "queueDeliveryPolicy=r"
Updating existing physical queue
jmqcmd update dst -n <name_of_queue> -t q -o "queueDeliveryPolicy=r"
See the documentation and jmqcmd -H for complete details.
