The ABL interface to Web service operations is a type of proxy procedure object that you map to a port type in a Web service binding (see
Connecting to OpenEdge SOAP Web Services from ABL). This
Web service procedure object provides access to port type's operations much like 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).
