JAX-WS is extension to JAX-RPC introduced in JEE1.5. And from Java1.6 onwards We can develop JAX-WS webservices using JDK itself. JAX-WS internally uses JAXB and SAAJ APIS.

What is the most widely used way of generating Webservices ( Axis server tools, or Java's own wsgen tool or any other )?

Ans: Mostly we use AXIS, CXF webservice engines to generate webservices.

Is it necessary to be proficient at XML, JAXP, JAXB, SAAJ, JAXR? I know a little bit of JAXP and while writing the example program I saw It was not needed explicitely ,things were done at the background by the tools.
Ans: It is good to have some knowledge on above mentioned APIs to understand JAX-WS.

Is there a way to create the services and generating clients be done in a vendor independent way?
Yes we can do it. From Java1.6 onwards to create webservices we dont require any webservice frameworks.JAX-WS is part of JDK it self.
