SERVICES 

I have a client that needs to access a service that is hidden behind a
firewall.  The client knows only about a "firewall" service that takes
requests and re-routes them to the proper internal service based on a
mapping file.  
Currently this is done using a Command Pattern, where the firewall
service and all internal services implement the same method signature
(executeApp(string, string)).  The firewall service has to pick off
one of the parameters to determine where the request should be routed.
 This is ineffient and does not really use SOAP the way it should or
could.  
I have been trying to find more information on WS-Routing,
WS-Addressing, etc, but I can't seem to find info on my scenario.
My question is, what is the best way to achieve this?  I need to hide
the final service destination from the client, but the client will
know the proper method and params to pass, just not the final
destination.  I need the intermediary firewall service to route the
request to the appropriate service.  However, I want to use SOAP to do
the routing rather than having to manually parse messages and send to
a standard method signature.  
I am currently running AXIS 1.1.

TIA,
Eric
