It's quite possible (probable actually) that there is a mismatch between the
namespace expectations on client and server, especially if the interface and
impl are in different packages. Definitely add the namespace attributes to
the @WebService annotations on both client and server.
Next thing to note:
On the server side, you are configuring in the AegisServiceConfiguration, but
you aren't on the client the side. That might also cause an issue.
Barring those fixing it, if you can create a jir and attach the full test
case, that would be a help.
