I highly recommend you to start by the new specification Jax-WS 2.0. It's a good idea walk on the standards.
Sun provides a reference implementation that you can use.
Try the JAX-WS web site and then you can watch the Metro web site to see all the standard ws-* stack.
I'm using this tool to consume and provide services. It's fast, easy to use, customizable and the standard.
Enjoy it!
