Just add service (Enslib.HTTP.GenericService) and operation (Enslib.HTTP.GenericOperation) to Your production. WS calls are anyway just http in lower level. If Your operation's URL is left empty, then it uses URL how service is called. So You need only one service/operation for one target server:port in Your production.
But You need to have quite new Ensemble. With older versions there are some bugs in those adapters, for example getting wsdl through this configuration is not working.
Anyway this is extremely easy to set up and give it a try.
