Quiero configurar SSL para websocket de una manera, básicamente, el servidor envía información a la página web y necesito esta seguro. He configurado la tubería de la siguiente manera:

ChannelPipeline pipeline = Channels.pipeline();

SSLEngine engine = serverSslContext.getServerContext().createSSLEngine();
engine.setUseClientMode(false);
pipeline.addLast("ssl", new SslHandler(engine));        

pipeline.addLast("decoder", new HttpRequestDecoder());
pipeline.addLast("aggregator", new HttpChunkAggregator(65536));
pipeline.addLast("encoder", new HttpResponseEncoder());
pipeline.addLast("handler", webSocketHandler);

mi manejador

public class WebSocketHandler extends SimpleChannelUpstreamHandler {

public void messageReceived(ChannelHandlerContext ctx, MessageEvent event) throws Exception {.... }

public void channelDisconnected(ChannelHandlerContext ctx, ChannelStateEvent e) throws Exception {.... }

}

mi clase sslserverContext:

 try {
            // Key store (Server side certificate)
            String algorithm = Security.getProperty("ssl.KeyManagerFactory.algorithm");
            if (algorithm == null) {
                algorithm = "SunX509";
            }

            try {
                KeyStore ks = KeyStore.getInstance("JKS");
                FileInputStream fin = new FileInputStream(keyStoreFilePath);
                ks.load(fin, keyStoreFilePassword.toCharArray());

                // Set up key manager factory to use our key store
                // Assume key password is the same as the key store file
                // password
                KeyManagerFactory kmf = KeyManagerFactory.getInstance(algorithm);
                kmf.init(ks, keyStoreFilePassword.toCharArray());

                // Initialise the SSLContext to work with our key managers.
                serverContext = SSLContext.getInstance(PROTOCOL);
                serverContext.init(kmf.getKeyManagers(), null, null);
            } catch (Exception e) {
                throw new Error("Failed to initialize the server-side SSLContext", e);
            }
        } catch (Exception ex) {
            if (LOGGER.isErrorEnabled()) {
                LOGGER.error("Error initializing SslContextManager. " + ex.getMessage(), ex);
            }
            //System.exit(1);
        } 

mi página javascript:

        var location =  ws://localhost:8989/websocket;

        ws = new WebSocket(location);
        ws.onopen = function(event) { alert("open"); }          
        ws.onclose = function(event) { alert("closed"); }

Cada vez que intento conectarme, con ssl configurado se llama "channelDisconnected", pero nunca más, el método "messageRecieved" nunca se llama. Sin embargo, si quito el controlador ssl de la canalización, todo funciona bien, he intentado seguir el ejemplo:

https://github.com/netty/netty/blob/3/src/main/java/org/jboss/netty/example/http/websocketx

¿Alguien tiene alguna idea?

La excepción que estoy obteniendo es la siguiente:

org.jboss.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record: 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
