JMS + ActiveMQ: exclusive access to data

Good day everyone.

1) I have a simple app which creates JMSProducer, ActiveMQ Query and send some messages to query.

2) I also have the application which is a subscriber of ActiveMQ Query (it receives messages from application above).

This is the situation:

I create another server config to my subscriber-App, and launch it twice at a time on different ports. (for example: subscriber-App1 started at jetty-http-port-9998/jetty-ssl-port-9994; subscriber-App2 started at jetty-http-port-9999/jetty-ssl-port-9995).

I open subscriber-App1 console and subscriber-App2 console at Intellij IDEa and begin to send messages by producer-App. And I see that subscribers takes messages by rotation: when I send it the first time - subscriber1 takes it; 2nd time - subscriber2; 3rd time - subscriber1 etc.

The question is: how can I configure subscriber-Application to give it exclusive access to data? The main condition is: if there is the one Subscriber of my Queue - another applications can't receive messages from Queue. And if I launch two subscriberApps on different ports - all messages will be received by only one of them.

Thank you in advance!

It is not clear what you are trying to achieve? If you want to make sure just "your" consumer ("subscriber" is more of a pub-sub, i.e. topic related, term) attaches to the queue, then just secure the broker. If you want to make sure there is only 1 instance of your consumer it gets trickier. Can you clarify what you are trying to achieve? – sceaj

I believe you should be able to use the exclusive consumer feature to achieve your goal.
