1. SERVER SIDE:
------------------------------------------
The server program is: webs14.java. Its purpose is to listen to port 9999.
When a client connects, the server passes the data it receives to
another program: chath20.java, which keeps a list of the current clients
to broadcast the latest data.

You start the server with the command:

	java webs14 9999
