OK, I'll try and find out how I use JAXB in place of Aegis. Could you
provide a pointer to some docs etc ?

So I mean that if the HTTP service is configured to listen to port 9000
then if I set the property like this :
props.put("org.apache.cxf.rs.address","http://localhost:9000/greeter2";);
then that works fine.
However, I'd rather not do that (set an absolute address) as we have
different configurations for our different environments.
