Studied the organizationalstructure of Apache MINA framework and how it works and then the realization of theprinciple of further analysis Openfire analysis. Detailed analyzed functional requirementsand performance requirements of the system for the instant messaging server and client,and complete a simple design of the framework of the system. Designed instant messagingserver and client and explained the Openfire server installation and configuration, designedthe main function of the client. On the implementation through the realization of the mainfunctional modules screenshots to explain main function module.
