Do not use JAX-RPC Clients

This rule flags references to the use of the <jaxrpc-mapping-file> element.

JAX-WS 2.0 uses JAXB 2.0 for data-binding between Java and XML whereas JAX-RPC 1.0 specified a limited mapping between XML and Java.
This effectively eliminates the need of using JAX-RPC mapping file where we define the mapping between Java and WSDL.
