Once you define an AppObject, its application methods and any related SubAppObjects and ProcObjects, ProxyGen can generate the proxy or SOAP Web service definition that exposes these objects to Open Clients.

For Java and .NET clients, the client code accesses the proxy in the client's native environment. As a result, a Java client sees the proxy (and the AppServer application service) as a set of Java classes, while a .NET client sees the proxy as a set of .NET classes. To use proxy objects, you must deploy the generated proxy along with the Open Client Runtime to all client application development and deployment systems. See Configuration.

For Web service clients, the client accesses the Web service in the client's native environment. The Web service definition (the WSDL document) is available through the WSA instance hosting the Web service. To use the Web service, there is no deployment requirement for the client.
