Description
Chat server's principal class is ChatServer that listens on socket for new connections. It instantiates a new threaded client back-end for each new connection (as instance of the ChatServerClient class) and keeps all such client connections in the ChatServer.clients list. Client back-end thread purges itself from the list after remote end is disconnected.
ChatServerClient will receive messages in ChatServerClient.run() from the remote client and call-back servers's ChatServer.broadcast() method that will distribute message to all connected clients.
Server may also opriginate its own messages, which will be prefixed with the "[System] :: ".
After receiving "wwhhoo" message, server will broadcast a list of all connected clients in the form: WWHHOO: <client-hostname>:<port>.
One can start application with the following command:
java -jar chatServer.jar [ <port> ]
where the default port is 2000
Joseph Weizenbaum's Eliza
If the server detects that the user is alone in the chat-room, it will offer to user to talk to an instance of Joseph Weizenbaum's Eliza, a simulation of a Rogerian psychoterapist implemented by Charles Chayeden.
The server will start Eliza in respond to user message talk eliza (ignoring spaces and character cases).
