In EPractice Lab, a question "A developer is migrating all of the company's JAX-RPC services into JAX-WS."
Which are true?
A. JAX-WS is essentially JAX-RPC 2.0 and is backward compatible with JAX-RPC services.
B. Deployment descriptors from JAX-RPC can be used under JAX-WS.
C. Deployment descriptors are no longer required.
D. jaxax.xml.ws.Service is a server-side API
E. javax.xml.ws.Service is a client API.
F. sun-jaxws.xml is the standard Java EE deployement decriptor.
I believe the answer should be A, C and E.
But the given answer is C and E.
The explanation from EPractice Lab , "JAX-RPC 2.0 was renamed JAX-WS 2.0..."
By reading this statement, it is very obviously JAX-WS is essentially JAX-RPC 2.0.
Also I believe the RPC/literal mode of JAX-WS is for backward compatibility of JAX-RPC 1.0
