You can provide a gateway Web service; that is, develop a Web service that is a contact point for other Web services.
All Web service requests are sent to the gateway Web service application. In the most-general case, the Web service requests are handled by separate JADE systems on separate computers.
The gateway Web service application provides no services of its own, and it simply redirects requests provided by the CustomerWebService service to WebApp1 running on host1 and requests provided by the ProductWebService service to WebApp2 running on host2.
