Finding User's IP Address.

I'm looking for a complete program (in .class type) that will do the following thing :

Let's say I have a chat, which consists of 10 users at the present. I want to find the IP address of one of the users (not the chat IP, the user IP).

I'm giving a lot of points, because I need it bbbaaaddd.

The function you are looking for, is it internal or external to the chat program. That is are you going to write a chat program in Java and looking for a particular module implementation or you have an existing chat program and want an independent application which determines user's IP addresses?

Depending on your implementation and chat server protocol, the *exact* way you'd go about getting the user's ip address will vary, but in general the answer is relatively simple:

Assuming you're writing a chat server, you will have a java.net.ServerSocket doing a
  server.accept();
somewhere.

accept() returns a java.net.Socket connection to the remote host.

All you would have to do to get the ip address of that remove host is something like this:
  Socket client = server.accept();
  String clientIp = client.getInetAddress().getHostAddress();

And then if you stored these clientIp Strings somewhere with mappings to usernames (such as a Hashtable), you would easily be able to retrieve the ip adress of any particular username.

I'm sorry, But I asked for a full program in Java, Since I don't have the slightest idea in Java programming. I'm increasing the points as a good will gesture, And hope I will get my answer soon.

P.S. If you need the address of the chat, it's :

I want to find the IP number of any user I choose, not the IP number of the srever the chat is working from.
