help you fix your problem ended up creating one reader channel that actually reads on the server, and then reroutes the packets to the different sender channels to be processed and then send a response.

Does that help You simply create several ServerBootstrap instances using a single ChannelFactory. For example:
code :
    NioServerSocketChannelFactory factory = new NioServerSocketChannelFactory(
            Executors.newCachedThreadPool(), Executors.newCachedThreadPool());

    ServerBootstrap bootstrap1 = new ServerBootstrap(factory);
    bootstrap1.setPipelineFactory(...);
    bootstrap1.bind(new InetSocketAddress(port1));

    ServerBootstrap bootstrap2 = new ServerBootstrap(factory);
    bootstrap2.setPipelineFactory(...);
    bootstrap2.bind(new InetSocketAddress(port2));
@Override
public void channelBound(ChannelHandlerContext ctx, ChannelStateEvent e) throws Exception {
    ctx.getPipeline().addLast("new", new SimpleChannelUpstreamHandler() {
        @Override
        public void messageReceived(ChannelHandlerContext ctx, MessageEvent e) throws Exception {
             ...
        }
    });
}

I hope this helps . You have to flip() the buffer to get data out of it. NB you should be using limit(), not capacity(), in that line.

wish helps you There is an option (checkbox) under the Web Tab Project Properties to move the user's port setting out of the project file called "Apply server settings to all users (store in project file)". Un-checking this box should allow users to have their own port setting values. MSDN article.

I wish this help you I don't think that it is possible to run two apps on one port. Using a reverse-proxy won't really work since it won't know which app to forward the request to.
What you will have to do is run them on different ports, other then that what you can try to do(given the 3 apps are small) is to combine them into one app using blueprints. Another way you can go about doing this is to do subdomains so like:
