WST supports the following service styles:
RPC – the body of the SOAP message is an RPC call containing the method name and serialized versions of the parameters. RPC services use the SOAP RPC conventions, and also encoding rules defined in section five of the SOAP specification.
Document –the body of the SOAP message is viewed as an XML document, as opposed to an RPC call. Document services do not use any encoding, but still provide XML-to-Java databindings.
Wrapped – similar to document services, except that rather than binding the entire SOAP body into one big structure, they “unwrap” the body into individual parameters.
