JAX-ws package refereed for CXF client

Hi Team,

I am new to CXF.I am trying to create CXF client using eclipse client
option.Using wsdl file i have created stub,But stub code i can't see CXF
packages reference.All the stub java class refer java-ws packge only.

I am not sure why?.When i run stub code it work fine without any CXF jar
file in classpath?.I am not sure how?.

I want to use CXF 3.0.3 client for my stub.Can you tell me what are the jar
file i need to include in my classpath.

What is the advance if i run stub using jax-ws vs CXF?

Thanks in advance.

Regards
