Difference between JAX-WS, Axis2 and CXF

Question

What is the difference between:

1. JAX-WS
2. Axis2
3. CXF

All three can be used to create webservices in Java.
As of I know JAX-WS

Answer 1

In short.

WSDL WS-* are language-agnostic.

JAX-WS are Java standard to build web service.

Apache CXF and Apache Axis 2 are two implementations of JAX-WS. They also offer JAX-RS implementations so that you can build Restful services.

CXF has better integration with Spring, and Camel(camel-cxf). And Axis 2 seems not have a active release.
