Release 10.1A: OpenEdge Getting Started:
Application and Integration Services

Overview of the Open Client Toolkit

Figure 4–2 shows how OpenEdge allows you to define a client interface using the Open Client Toolkit.

Figure 4–2: Client interface definition for Open Clients

Using the ProxyGen tool, you specify the procedures of the AppServer application service that you want to include in the client interface and how you want to represent them in terms of the Open Client object model. From this common interface definition, you can then generate for a:

.NET Open Client — Proxy objects in the form of a .NET assembly.
Java Open Client — Proxy objects in the form of a set of Java classes.
Web service Open Client — The client interface definition in a form that eventually becomes a WSDL file for use by Web service clients (or client developers) to generate the client interface itself.

The Open Client Toolkit contains additional tools to facilitate Open Client implementation, depending on the type of Open Client. For more information on ProxyGen and the entire Open Client Toolkit, see OpenEdge Development: Open Client Introduction and Programming .
