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

Web service clients

Web service clients include any industry Web service client, including a Progress 4GL application accessing the AppServer as a Web service. A Progress 4GL client can access the AppServer as a Web service in the same way it can access any industry Web service. However, Progress Software Corporation recommends, where possible, that you access the AppServer from a 4GL client using a direct AppServer connection to achieve optimal performance. For more information, see the "Progress 4GL clients" section. For more information on how a 4GL client can access a Web service as a Web service client, see Chapter 6, "Web Services in OpenEdge—Architecture and Tools," in this manual.

Any Web service client access to an AppServer depends on the OpenEdge Web Services Adapter, which allows any Web service client to access an AppServer application service as an industry Web service. For more information, see the "AppServer adapters overview" section.
