Single Java Socket

I have a Client/Server Java application written and working via a Socket.
Now what I want is for only ONE connection to be allowed to this socket.
How can I code it so that only one user can access the Server Socket at a time?
I have tried:
kkSocket = new Socket("rock", 5555,1);
But it is not doing anything when two people connect at the same time.
Thanx!

My guess, you control that behavior on the ServerSocket side. When you create a server socket you have to call serverSocket.accept() before client sockets can connect to it. Usually this is done in a loop where you accept a connection, spawn a separate thread to process it and continue listening. In your case you call accept() (which blocks the thread) and then connection comes in you stop listening (by not calling accept() again, or call accept() only after the existing connection is closed).

If that does not work, you can provide some application level logic where you count number of incoming connections and after establishing one connection you reject all the subsequent ones until that one disconnects.

I've been looking at the server side. As of now I don't have it doing what
I want.  But I see what you are talking about.  I'll keep working it, I think
that I can make it happen.  Thanx!
