Implementing Web Service Client

Two flavors:
1. Standalone JAX-RPC clients without JNDI access for service lookup
Two coding approaches:
a) static stub
relies on statically generated SOAP client stubs, much like RMI stubs.
b)dynamic proxy
retrieves a WSDL description at runtime to generate the dynamic proxy from it.
Both approaches rely on the client’s knowledge of the service endpoint address URL and not just a symbolic lookup name as with JNDI. These approaches are functionally equivalent.

2. J2EE clients (both Web clients and standalone) that can access client side JNDI contexts
