Release 10.1A: OpenEdge Application Server:
Developing AppServer Applications

Programming Progress 4GL Client Applications

This chapter describes how to program Progress 4GL procedures that execute in an Progress 4GL session that runs as a client to an AppServer. Specifically, the sections in this chapter describe:

Programming for the AppServer session model
Progress 4GL for programming AppServer client procedures
Accessing AppServer resources from a client
Connecting an application service or AppServer instance
Accessing the connection ID on the client
Running and managing remote procedures
Disconnecting from an AppServer instance
Handling conditions and return values
Managing asynchronous requests

This chapter addresses programming issues specific to Progress 4GL client procedures of an AppServer or application service. It assumes that you are generally familiar with writing and executing Progress 4GL procedures. For information on using the Progress 4GL, see OpenEdge Development: Progress 4GL Handbook . While there is some reference to Open Clients, for complete information on programming Java, .NET, and Web service Open Clients, see OpenEdge Development: Open Client Introduction and Programming .
