title: (How) can I use ServerSocket to listen for UDP instead of TCP traffic?
body: <p>In my application, there's a module that uses <code>ServerSocket</code> to listen for incoming TCP connections. When I switched a client to use UDP, I expected to receive data anyway, but I was wrong. When I looked at the documentation, however, I couldn't find any config option to set up the socket for UDP. Do I have to use a different class?</p>
