So, looks like your DestinationStamperProcessor adds a "url" header which is
the desired destination? If so, you could use either a dynamic recipientList
(http://activemq.apache.org/camel/recipient-list.html) or routingSlip (
http://activemq.apache.org/camel/routing-slip.html) to send to a dynamic
destination. For example,
...recipientList(header("url"))
would send incoming messages to the endpoint defined in the header "url"
Hope this helps.
Cheers,
Jon
