The Research Of System Application Integration In Digital Campus Based On J2EE/EAI

The digitized campus is using computer technology, the network technology and the communication technology to carry on the comprehensive digitization that related all information resource of the school teaching, the scientific research management and the life service, in order to constitute the unified user management, resource management and jurisdiction control, the system carries on the conformity and the integration with the scientific standard management to these information resources. The aim of the construction of digitized campus is to integrate the independent and disperse subsystem , eliminates the isolation of school information, effectively realizes data sharing, solves repetition management, redundancy and not synchronization of the data.In this paper, the background and the the present status of the digital campus system were first elaborated and the main problems existing in the construction of the digital campus system were pointed out. Then the technological constitution of the Web Services and EAI were studied. The key technologies in the construction of digital campus system, including application server WebServices, EJB technology were introduced and the application of these technologies were also studied in this paper。The Applications use JSP achieve layer and WebServices, EJB as the key technology services layer, the design and realization of the digital campus system of the various subsystems for application integration method and critical technologies, and the library management system and the one Card System is achieving.Digital Campus system follows the J2EE standard, because of EAI, the author resolves the problem of"Information Island"in the construction digital campus system, each system can communicate with others conveniently. This kind of develop pattern, provide a new pattern in the development of digital campus system.
