[jetty-users] NPE in WebSocketServlet

["Benedikt Arnold" <benedikt.arnold@xxxxxxx>]

Hi,
my name is Ben and I'm new to jetty users list.

I want to try out websockets whith jetty 7.0.1 but I got a NullPointerException in WebSocketServlet#service() on line 58 because the http object is null. See stacktrace below.

My own implementation of WebSocketServlet is very simple:

public class CountWebSocketServlet extends WebSocketServlet {

	protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		getServletContext().getNamedDispatcher("default").forward(request,
				response);
	}

	protected WebSocket doWebSocketConnect(HttpServletRequest arg0, String arg1) {
		return new CountWebSocket();
	}
}

Can anyone give me a hint or is this still a bug?

Thanks a lot,
Ben
