Showcasing dynamic soap proxy with wsdlDriver

I’m attempting to convince some naysayers on the values of dynamic
languages by creating a fully dynamic SOAP proxy at runtime.
wsdlDriverFactory is working like a champ. I have two questions. 1) At
runtime, how do I determine what methods were added dynamically to the
rpc driver and 2) how do I determine the structure of the parameter hash
to be passed to a given method? For example:

ws_client =“http://mywsdl”).create_rpc_driver

works great


… a big list of methods, is there anyway to see just those that were

specified in the wsdl?

some_response = ws_client.mySoapMethod(:key1 => value1)

Is there some way to understand what arguments (keys, values) the

method expects programmatically at runtime?
