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

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...

or you can use an expression to determine the exact queue to send to
via a dynamic recipient list


which for a message


would be routed to the ActiveMQ queue "Foo.Cheese"

either create your own classloader and use an embedded broker; write a
normal spring application and include the activemq.xml file - or jar
up your camel code and drop it into the standard ActiveMQ activemq/lib

Yes - or you can use the <camelContext> <package>...</package> to
describe the packages to search for RouteBuilder classes
