Based Ajax Technology J2ee Application Framework

With the development of the web technology and the users'increasing request for applying the web, the traditional interactive pattern on the basis of request-response has difficulty to satisfy the users'experience. As the frontier technology in web realm, Ajax provides the new Internet interactive pattern. Meanwhile, an application procedure which provides good experience for the users can be constructed with Ajax. Although Ajax technology is extensively applied in the Web development, the research on Ajax design pattern is most about some models of the Ajax technology application and the elaboration of Ajax foundation design's theory.Firstly according to the traditional Web application procedure's research, this paper points out its insufficiency, and briefly describes the characters that next generation Web application should have. In the above foundation, it introduces Ajax technology which can solve these questions. Analyze the technology of Ajax compare which compared with the traditional Web, and analyze the work principle and its key technology of Ajax thoroughly.Through the deep research of Ajax technology and the web application under J2EE architecture, associating with the recommended MVC pattern in the J2EE platform, with their respective characters, and carrying on integration and innovation, it proposes the Web development pattern by the framework of Ajax and J2EE.Finally, applying the new development pattern proposed in this article, it has realized a blog application system. It proves the possibility and functionality of the J2EE frame and the Ajax frame comprehensively. In the realization process of the system, it constructs and realizes the pre-load buffer mechanism on the basis of Ajax and applies the Reverse Ajax technique. It compares and analyses the consumption of the web between the Ajax model and the traditional model by the device of network traffic monitoring. Ultimately it draws the conclusion, the use of the new pattern not only makes the Web clarity in different levels and strong reusability, but also reduces server's load effectively. It provides a perfect operation experience for the user.
