| With the rise of Web2.0, the improvement of user interaction experience becomes a hot topic among the majority of developers and designers. Ajax, as the core technology of Web2.0, has been gradually widespread concern, research and application. One of the biggest advantages of Ajax is the ability to offer asynchronous interaction between browser-side and server-side. This approach of interaction can effectively reduce the burden on the server. Through in-depth study on Ajax technology and WSH which is one of the most popular open source framework under the J2EE architecture, combining the MVC pattern which is relatively mature nowadays, according to the characteristics of them, the article proposed a RIA framework which is based on Ajax technology and J2EE architecture, it can not only improve the reusability and program scalability, but also reduce the complexity of post-maintenance.Based on the integrated framework, this article has been achieved the specific design and development of horizontal approval management system, further demonstrating the feasibility and operability of this framework. The article realized active and inactive refresh, also achieve the server-side push by using the DWR inverse mechanism in Ajax. Finally comes the conclusion that the integrated framework can reduce the coupling among the presentation layer, business logic and data persistence layer, in the same time, it makes the layers clear in Web applications with highly reusable. By using Ajax and its framework, this article has been solved many problems in traditional Web applications and greatly improved the interaction experience.This article proposed a development model with seamless integration between DWR and WSH framework in specific designing and implementation. With the using of this development model, the article achieved horizontal approval management system which demonstrates the enormous advantages of this integration. |
