How can you listen to multiple queues in WSO2 ESB

I am creating a hosted system where multiple customers can send messages. I am receiving thoses messages on a JMS queue.

Now, all processing is done in a similar way and I want my process to poll all incoming queues for messages and handle them. Is there a way in WSO2 ESB to subscribe to multiple queues?

If not possible, the workaround would be to create a seperate listener process for each queue and have this post the message to a central processing queue. But that seems to be a less clean solution (and I think it will scale worse than listening to multiple queues).

Any ideas on this?

If changes to activeMQ server is possible ie. if OP is able to influence the configuration to the server, something like ActiveMQ diverts could do the trick.

<divert name="prices-divert">
   <address>jms.queue.ABC</address>
   <forwarding-address>jms.queue.theone</forwarding-address>
   <exclusive>true</exclusive>
</divert>

<divert name="prices-divert">
   <address>jms.queue.xyz</address>
   <forwarding-address>jms.queue.theone</forwarding-address>
   <exclusive>true</exclusive>
</divert>

Basically, multiple diverts that converge the messages from multiple queues to the single queue. This method has advantage over the reading and writing to single queue-as mentioned by the OP and would in my view scale well as it is inbuilt feature.

You can define a sequence with all the required logic in it and then call it from multiple proxy services (each listening to a specific queue). Otherwise you can try something similar to this sample.
