Hey, is there any way to reject WebSocket writes from client side? I want clients only to listen and not waste jetty resources if someone would spam the connection with messages. So basically one direction messaging, server to client.

have you tried setting policy to accept 1 byte only (I think 0 didn't work for me)?

 public class MyServlet extends WebSocketServlet {

    @Override

    public void configure(WebSocketServletFactory factory) {

        factory.getPolicy().setMaxBinaryMessageSize(1);

        factory.getPolicy().setMaxTextMessageSize(1);

        factory.register(MyListener.class);

    }

}
