For Java Open Clients, the supported application server operating modes are the session-managed modes of state-aware, state-reset, and stateless, and the session-free mode, state-free. For more information, see the information on session models in the chapter on generating proxies and Web service definitions in Learn about Open Clients.

To access a session-free application server, you must set the proxy property PROGRESS.Session.sessionModel to 1. For more information, see Access Proxy Properties.
