Re: WSS Upgrade Failed with AsyncHttpClient and Grizzly WebSockets

The root of the problem is that the WebSocketAddon isn't actually being
registered as Jersey is starting the server before handing back the
server instance. AddOns currently aren't able to be dynamically
registered. So for this, I would recommend logging an issue against
Jersey to have an option
to have server instances not being started automatically.

The obvious thing to do then, as a workaround, is to stop the server,
add the WebSocketAddon, and then start the server again, but it appears
we're too aggressive with the listeners when the server is stopped.
This is something we'll address for the next release.

Here's a workaround that, while ugly, does get you moving forward:


public SimpleServer() throws Exception {
             URI uri =
                     
UriBuilder.fromUri("https://localhost").port(4443).build();
             HttpServer webServer;
             SSLContextConfigurator sslContext = new
                     SSLContextConfigurator();
             sslContext.setKeyStoreFile(keyStorePath);
             sslContext.setKeyStorePass(keyStorePass);
             webServer =
                     GrizzlyServerFactory.createHttpServer(uri, null, true,
                             new
                                     
SSLEngineConfigurator(sslContext).setClientMode(false)

                                     .setNeedClientAuth(false));
             NetworkListener l = webServer.getListener("grizzly");
             webServer.stop();
             webServer.addListener(l);
             // add the WebSocketFilter manually
             FilterChain c = l.getFilterChain();
             final int httpServerFilterIdx =
c.indexOfType(HttpServerFilter.class);

             if (httpServerFilterIdx >= 0) {
                 // Insert the WebSocketFilter right after HttpCodecFilter
                 c.add(httpServerFilterIdx, new WebSocketFilter());
             }
             WebSocketEngine.getEngine().register(new
                     EchoApplication());
             webServer.start();
         }
