This is my generic Chat Applet.
Implemented in Java and the server is run on Linux machine. It may not be possible for me to run the server at all times. So you might see the message. Connection to the server failed. When the server is running you will not see any message. I will try to update the code to give the list of all the users who were connected at that particular time. Till then you will not be knowing who all are connected unless they chat. All the messages you type will be broadcasted to all the clients connected.
