The Research And Practice Of A E-Commerce Framework Based On J2EE

Along with the popularity of Internet and development of computer technology, especially the maturity of Web application technology, providing services in Internet are required by many enterprises and departments dramatically. At the same time, as a result of the popularity of PC and Broad Band greatly, more benefits are wanted to obtain by people through computer network. Consequently, the opportunity of E-Commerce is grown up unconsciously. The software architecture is focused on what components should be used to set up software system and the relationships between these modules. The paper analyses advantages and disadvantages of all kinds of software architectures, and causes of their developmets. After that, the paper introduces the architecture and components of J2EE. And then gives a framework of devloping E-Commerce system based on J2EE. The framework has multilayer architecture of J2EE, and reuses many functions of J2EE. And the Framework reduces the coupling degrees of tiers in a certain extent. It is good for decreasing complexity of enterprise software and tracking lifecycle of software. And it has good manageability and maintainability. In the end of the paper, gives a instance based on the framework--a Steel Electronic Dealing System. Through the Design and Implementation of this system, we can see that J2EE as a extensible plateform is becoming a virtual criterion of establishing E-Commerce application and J2EE will be used widely in future.
