TCP/IP server applications rely on a networking class provided by Java, java.net.ServerSocket. This class takes most of the work out of establishing a server. ServerSocket allows you to bind a port and wait for clients to connect, setting up a complete Socket object at that time. After communications are complete with the client, the server must close the streams and then close the Socket instance.
Since the application requires multi-user, with Java's multithreading available, the creation of multithreaded server application is used which allows simultaneous connections with many clients. This multithreaded-server structural design is specifically network servers utilise.
In this dissertation, the use of Java Networking Sockets to create multi-user online chat system is presented. In order to provide real-time instant access to clients, the client application is installed or embedded on a web page for easy access as java applet.
