Implementation of Enterprise Instant Communicating System Based on Application Layer with Java Programming

Communication is important to enterprise, the paper constructed an enterprise instant communicating system based on application layer using the socket mechanism of Java language, introduced briefly the establishment of communication mechanism of application layer in client and server side, then analyzed the design of the main function of client and the database on the server. The enterprise instant communicating system adapted the three layers model as its basic frame with the socket and alternative network technology, it also utilized user login validating to manage and control the online users. The result of testing shows that the system is robust and has a friendly user interface. The system can be fit to the enterprise inner information communication and relating work.
