How to consume from multiple JMS queues?
Hello all,
I need a route to consume from multiple JMS (not activemq) queues. It seems
that the JMS Component does not have a direct way to do this. To add to the
complexity, the queues that the route reads from can change during runtime.
Can someone guide me how this can be done within Camel?
Thanks

You could use one queue and jms selectors. See:

Each queue contains data for a separate customer. Customers can pull data
from their queue indirectly via a web service call they make to us which
pulls from the company queues and return the resulting messages. However,
there are some customers who want us to "push" data to them by calling their
web service.
It is this second scenario I need to implement. Since all this data is
handled the same way, I just wanted one route which reads from these queues,
processes the data, and sends the data to the customer by calling their web
service endpoint. I can try Claus's suggestion. Another option is to
change the process that writes to the queues to only write to one common
queue, but I was hoping to avoid that.

For queues this does not work but you could try topics with wildcards. I
think that should work with pure JMS.
Can you tell us a bit more about the use case? Perhaps this can also be
solved differently.

AMQ supports wildcard in destinations so a consumer can consume from
multiple queues.
But that is an AMQ specific feature.
You can add multiple from to a route.
You can add new routes at runtime, so the new routes consume from the
new queues.
Likewise you can stop/remove routes as well.
