Release 10.1A: OpenEdge Development:
Web Services

Preparing to invoke operations

The 4GL interface to Web service operations is a type of proxy procedure object that you map to a port type supported by a given Web service binding (see Chapter 9 "Connecting to Web Services from the Progress 4GL"). This Web service procedure object provides access to operations defined by a port type in much the same way that a proxy procedure object provides access to remote internal procedures and user-defined functions defined by a persistent procedure instantiated on an AppServer (see OpenEdge Application Server: Developing AppServer Applications ).
