Hi Danny,
"because it retrieved all the open sessions for all the endpoints " .. I agree. "What is it you need to be able to do?" Ohh many things ;-) If I have N backoffice systemes communicating through one Endpoint the session.getOpenSessions() solution is fine. If you have in this scenario some external systems who wants to notify all BO's on this Endpoint you can do this only with a workaround (open a connection to this speciffic endpoint, send the message, close)... or you use thigs like SSE and notify your connected applications (or any other).
WebsocketEndpoint can be either Stateless or Singleton beans (in EJB world), so I want simply be able to say endpointEJB.notifyClients()...
Thank you
Andy

The use case for this is really for a single endpoint to be able to easily broadcast an update to its connected clients (and not the connected clients of other endpoints in the application). So, the call being there had a few problems:
