The PowerBuilder application server proxy enables PowerBuilder clients to communicate with EJB session beans, using a Connection object. The EJB session beans must be running in one of the application servers defined in “Installing and Configuring the PowerBuilder Server Plug-In”.
The PowerBuilder Application Server Plug-In includes two editions of the proxy server:
Client – runs as a separate process on the same machine as your PowerBuilder client application.
Server – runs as a separate process on the same machine as your application server.
