Hi!
I am trying to use ActiveMQ and Stomp protocol to implement scenario
where are multiple consumers are processing messages from single
queue. I want to make sure that only one consumer will get the
message, and he must acknowledge it, so the message will get back to
queue if it has not acknowledged for some time.
One of problems I see is that there is no NAK command in stomp. So,
once I have received the message I could not send NAK to reject it
back to the queue, so it will be delivered to another consumer.
Another problem, or rather a question, is what happens to not ACK-ed
messages. Are they delivered to other consumers and under what
conditions?
Perhaps I can use stomp transactions, but I am not sure how they apply
to receiving messages.
Sincerely,
Vadim
