Question

I’m trying to run Netty Draft10 latest example on top of SSL (WSS)

https://github.com/netty/netty/tree/master/src/main/java/org/jboss/netty/example/http/websocketx/server

I’m using the following port configuration:

Port: 80: Apache non ssl
Port: 443: Apache ssl
Port: 8080: Tomcat
Port: 8877: Netty Web non SS
Port: 9977: Netty SSL

But when I embedd the SSL handler code

public void channelConnected(ChannelHandlerContext ctx, ChannelStateEvent e) throws Exception {

    //TODO - Tamir - Add support for Wss
    // Get the SslHandler in the current pipeline.
    // We added it in SecureChatPipelineFactory.
    final SslHandler sslHandler = ctx.getPipeline().get(SslHandler.class);

    // Get notified when SSL handshake is done.
    ChannelFuture handshakeFuture = sslHandler.handshake();
    handshakeFuture.addListener(new Greeter(sslHandler));
}

into the WebSocketServerHandler class I get an error message

java.lang.IllegalArgumentException: empty text

        at java.lang.Thread.run(Thread.java:662) 
java.lang.IllegalArgumentException: invalid version format: ?_?_?__

This is my pipeline code

SSLEngine engine =
        SecureChatSslContextFactory.getServerContext().createSSLEngine();
    engine.setUseClientMode(false);

    pipeline.addLast("ssl", new SslHandler(engine));

    // On top of the SSL handler, add the text line codec.
    pipeline.addLast("decoder", new StringDecoder());
    pipeline.addLast("encoder", new StringEncoder());

    // and then business logic.
    pipeline.addLast("handler", new WebSocketServerHandler());

Any ideas?

Cheers,

Tamir

I’ve just uploaded a working example of web sockets with SSL which I’ve merged with master.

See pull request: https://github.com/netty/netty/pull/53.

The new code is in src/main/java/org/jboss/netty/example/http/websocketx/sslserver

Please read package-info.java for setup instructions.

Let me know if it works for you.
