I would stay away from "J2EE Web Services: XML SOAP WSDL UDDI WS-I JAX-RPC JAXR SAAJ JAXP" because it sounds like it is based on the old jax-rpc standard.
Starting with JEE 5, jax-rpc was replaced witth jax-ws and jaxb.
Java Web Services: Up and Running by By Martin Kalin is much more useful for OCPJWSD 6 certification. I have that book and I really like it.
Also, please get "SOA Using Java Web Services" by Mark Hansen, which I also have and like that one even better.
