Then either just add your routing rules to the activemq.xml - or drop your Java and Spring code into the activemq/lib directory as a jar > I ran the example that comes with ActiveMQ 5.1, where all messages > going to example.A get routed to example.B . > > I want to go further and be able to route based on conditions, to a > dynamic queue (read from memory). > > So as you see I need to be able to "include" a java class to handle this > routing. > > Problems so far: > > 1.

To route to a different queue name using the payload of the message to decide it you can either use a Content Based Router where you test for different values... http://activemq.apache.org/camel/content-based-router.html or you can use an expression to determine the exact queue to send to via a dynamic recipient list http://activemq.apache.org/camel/recipient-list.html e.g. from("activemq:someQueue").recipientList().xpath("concat('activemq:Foo.', /body/someValue"); which for a message <body> <someValue>Cheese</someValue> </body> would be routed to the ActiveMQ queue "Foo.Cheese" > 2.

Yes - or you can use the <camelContext> <package>...</package> to describe the packages to search for RouteBuilder classes These links might help a bit http://activemq.apache.org/camel/spring.html http://activemq.apache.org/camel/spring-example.html -- James ------- http://macstrac.blogspot.com/ Open Source Integration http://open.iona.com
