Design and Implementation of Web applications based on J2EE and Ajax

Web applications based on J2EE and AjaxProgramDesign and Implementation of Lijun (School of Computer and Information Technology, Beijing Jiao Tong University, Beijing 100044) Abstract: This paper compares the traditional Web applications with the Web applications of the Ajax model, the integration design mode of Ajax and J2EE is analyzed in detail, and the feasibility of this design is illustrated through a simple example. 1. Ajax introduction traditional web applications are a typical application of "starting the whole body". Each page of the client corresponds to a set of different logic on the server side, as shown in 1. Almost every tiny operation of a user will refresh the entire page. Such an application not only causes poor user experience, more importantly, it wastes a lot of network traffic to transmit redundant data and static page information. Figure 1 traditional Web applications that integrate Ajax technology greatly improve this point. Each operation can refresh only the necessary page areas and extract only the necessary data. In this case, the web page is equivalent to a separate application. data can be retrieved from multiple server logics and then reflected in the page. 2. Ajax is asynchronousjavascriptandxml. It is actually a combination of several mature technologies, including:
