The Study And Application Of Multi-tiers Web Application System Based On J2EE And UML

With the development of Internet/Intranet technology, more and more Web Applications are required. Application systems base on Web has become the dominating model for the computer application system. J2EE architecture provides a technical platform with reliable performance and good services for Web application system.But with the high-speed developing of the Web application system, most of them are used to develop the large-scale enterprise system. Meanwhile, the fields that it involved in are becoming broader, and the higher complexity of Web Application System are incurred. This means building a Web application system only with the pure J2EE technique will be more difficult. So we need to find a new way to develop the large-scale Web application system.This paper makes an in-depth study on the developing style of Web application system and extracts the software modeling process based on UML. By using UML extension mechanism, it extends the UML model scope, facilitates the modeling of the Web application system based on J2EE, makes the requirement of Web application system clear, standardizes the J2EE development process, lowers the developing complexity, speeds up the course from concept model to design implementation, explores a road to large-scale enterprise Web application system. Meanwhile, it employs J2EE architecture to implement the system with Struts architecture based on MVC pattern and simplify the process of development.At last, we make a conclusion of the work in this paper, bring forward some insufficiency in the research and envision of the research in the future.
