I think the Content-Based Router EIP is a good fit here, http://camel.apache.org/content-based-router.html. For example: from("jms:q2") .choice().when(body().isInstanceOf(M2.class)) .to("controlbus:routeId=Route1&action=start") .end() >> Is there something we can do to pause a Route while it waits for a message and resume it once the message arrives? If a route is paused it cannot do anything, its paused after all. You'll need another route or process to resume a route. Pausing/resuming routes can be done using the CamelContext ( http://camel.apache.org/how-can-i-stop-a-route-from-a-route.html) or using the ControlBus EIP (http://camel.apache.org/controlbus.html). The latter is easier to use, as illustrated in the code sample above. >> Can we raise an event so that any Route that is waiting for M2 can be resumed? >> What do we need to do to resume the route? Use the CamelContext API directly or use the ControlBus EIP as I mentioned Regards, Richard On Tue, Dec 31, 2013 at 5:56 PM, yashgt <yas...@gmail.com> wrote: > Hi, > > Route1: > Send Message M1 to MQ Q1. // This message goes to a program that > consumes > from Q1 and once some processing is done, write message M2 to Q2. > Upon receiving Message M2 on Q2, //Q2 receives several messages > (M2,N2,P2, > etc.).
