Hi!
I think I recall having read somewhere that the XML binding in JAX-RPC is not as complete as JAXB, which is what JAX-WS uses.
Some items from the JAX-WS specification:
- Client-side asynchronous service invocations.
- Substitution of deployment descriptors with annotations.
- Support for message based session management.
- Development of handlers has been simplified.
- Supports the WS-I Basic Profile version 1.1, as compared to version 1.0 for JAX-RPC.
There are probably more, but at least
you should have some more motivation to take a look at JAX-WS.
Best wishes!
