I wonder if a cxf:cxfEndpoint ( xmlns:cxf = "http://activemq.apache.org/camel/schema/cxfEndpoint" ) supports WS-Addressing? I haven't found anything yet. I know that jaxws:endpoint (xmlns:jaxws = "http://cxf.apache.org/jaxws") does.
Haven't tried this but starting from Camel 2.0 you can reference a bus instance in your Camel cxf: component configuration. See here.
Then place the jaxws:endpoint config into the same config file but explicitly reference the same bus instance as in your <jaxws:endpoint> config.
See here for documentation.
Hope this helps.
