The MiddleWare Technology Research And Application Based On Enterprise Javabeans

With the development of IT and the maturating of network, the management information system, which is lead by IT and integrated with network technology, becomes the preferred modern official system. The middleware is a new technology under the development of IT and network, it is booming while enterprises trend to be global. The enterprise' application is no longer satisfied with stand-alone and simple Clint/Server system, but developing towards 3 layers and multilayer distributed environment. In order to solve the problems under distributed environment, the standard of middleware technology came into being. This article introduced the start, classification, and standard of middleware technology, described the groupware technology EJB in detail, including the architecture, advantages of EJB, EJB and 3 layers architecture etc. The article also dissertated the develop process of Tianjin local science and technology award management system, including demand analysis, system design and implement. The development of this system is based on EJB and 3 layers middleware architecture, completely realized network operation, both the application and evaluation are carried through WAN, breached the limitation of traditional 2 layers C/S structure. The research achievement of this article is helpful to the local science and technology award evaluation process; at the same time it could be used for reference for development of other information systems.
