Implementation And Application Of Ajax Integration Framework Based On J2ee

With the development of web technology, B/S (Browser/Server) architecture ofsoftware applications has increasingly become the preferred architecture. Now thetraditional interaction pattern based on the request-response has difficultly met user’srequirements. As the leading edge of web technology, Ajax (Asynchronous JavaScriptand XML) provide a new interactive pattern, which greatly improves user’s experienceof B/S applications. However, JavaScript code for Ajax is difficult to read, maintainand causes security issues. Many Ajax frameworks have been developed to resolvethose issues, and have been widely used in development of web applications. However,the client frameworks focusing on the view layer, and lack of effective communicationwith servers while the server-side frameworks lack of expressive user interface.Building a powerful, easily expandable and maintainable integrated applicationframework with flexible architectures is a significant contribution to fast developmentof Ajax, code reuse of components, products and projects.We designed and implemented an Ajax web framework that includes client andserver-side framework and applied it to a practical project.On the side of server-side framework, many excellent open-source frameworkshave come up. These frameworks cover all layers of J2EE architecture and providehuge convenience for framework building. We designed and implemented the basis ofcontroller model layers. Hibernate is used to simplify database accessing and Spring isused to manage components, resources and transactions.On the side of client framework, we used jQuery to build an Ajax user interfacecomponents library. Components can communicate with the server via the frameworkand dynamically update information without refreshing the whole page.
