Problem with using external sockJS server

[matyas-igor]

Hi, Carl!
Your implementation of sockJS client is really awesome, but I can't use it because I can't send subscribe message.
I'm using external implementation of sockJS server (on PHP).

In javascript client code was like:

        sockjs = new SockJS('/echo');
        sockjs.onopen = function() {
            sockjs.send(JSON.stringify({subscribe: ['orders', 'deals']}));
            $('div').append('open '+ sockjs.protocol+'<br />');
        };

But I can't send it same message in java using your library.

I've tried to use something like:

            ClientBootstrap clientBootstrap = new ClientBootstrap(new NioClientSocketChannelFactory(Executors.newCachedThreadPool(), Executors.newCachedThreadPool()));
            SessionClient sessionClient = new SessionClient("http://localhost:8080/echo");

            WebSocketClient webSocketClient = new WebSocketClient(clientBootstrap, new URI("http://localhost:8080/echo"), sessionClient);
            ChannelFuture channelFuture = webSocketClient.connect();

            Channel channel = channelFuture.getChannel();
            webSocketClient.setChannel(channel);

            webSocketClient.send("{\"subscribe\":[\"orders\",\"deals\"]}");

But in this case I got message:
