Your problem is that for MessageRouter Services, you DO need to specify
functions on the server side code that match the signature
function_name(Envelope env, SOAPContext resCtx, SOAPContext reqCtx)
* The order of the SOAPContext parameters may not be correct; check the
sample code.
MessageRouter Services differ from RPC Services on the server side by the
function signature that you're having a problem with now, and on the client
side in how that service is invoked.
