Hi,
My Server is running as a Windows Service and I am wondering how to set ServerState to e.g. “SHUTDOWN” when the service is stopped?
Actually, the state according to client is changed to: ServerState changed from Running to CommunicationFault
Is there a listener for shutdown on server?
Thanks

UaClient is polling the ServerState (1000 ms by default), so it should notice the change, if you call UaServer.shutdown() with a 5 second delay, for example, when the service is requested to close. How do you run it as service – that’s the next question of course.
If the client fails to read Shutdown state, it will notice the change when the read fails – and it results to CommunicationFault.

Solved this topic by adding a simple ShutdownHook in main method. Btw, I use Tanuki Service Wrapper for starting the server as a service.
@Override
public void run() {
server.shutdown(5, new LocalizedText("OPC-UA Server was shutdown", Locale.ENGLISH));
}
});
