Is there a way for a java chat client program to dynamically find the host server?

I want to just execute an instance of client with no parameters other than the port number and have the program find the server listening on that port anywhere on the network.

You can use UDP multi-cast to find the server. You can send a UDP packet to the port and have the server respond with its IP address. (This effectively hard codes a multi-cast address) which is not much better than hardcoding a hostname which can be looked up via DNS.
