Subject RE: Design proposal for enhanced JAX-RPC handler functionality for the service control
Date Thu, 28 Jul 2005 02:01:41 GMT
My suggestion is (unless there is a good reason why we should not) to
reuse the javax.jws.HandlerChain and javax.jws.soap.SOAPMessageHandlers
annotation.    It would be nice not to invent new annotations if there
are already defined.

We may also be able to reuse the handler code of the WSM in the service
control.
