Question

I have a written a very simple UDP Server using Netty - it quite happily binds itself and accepts messages, but I can y figure out how to unbind it.

Am I missing something, or does Netty not expose the necessary APIs to unbind a server?

Edit

Here is the code I am using to bind the server:

DatagramChannelFactory f = new NioDatagramChannelFactory(Executors.newCachedThreadPool());
ConnectionlessBootstrap b = new ConnectionlessBootstrap(f);

ChannelPipeline p = b.getPipeline();
p.addLast("encoder", new StringEncoder());
p.addLast("decoder", new StringDecoder());
p.addLast("logic",   this);

chan = b.bind(new InetSocketAddress(port));

Answer 1

netty provides many entry points to setting up a server, I don t know which one you ve used.

You should be able to simply .unbind (or .close) the Channel you get back from ServerBootstrap.bind
