Study On Ajax And Soap Service Based Application Framework And Its Implement Method

With the rapid development of network technology, Web application has become more and more popular owning to its rich user interface and good maintainability. However, traditional Web applications face many problems, such as low-performance and high bandwidth, so the Web application based on Ajax turns up quietly.At present, there are many application frameworks according to Ajax, but they tend to focus on the local service process, few focus on remote service process, especially the UDDI service process. Therefore, the thesis aims to study on method of using Ajax technology to call Soap Service.Firstly, the thesis studied on Ajax basic skills, Soap Service, Web application framework and other theories and techniques. On this basis, it proposed a Web application framework based on Ajax and Soap Service (Ajax and Soap Service based Framework, ASSF). The thesis also gives the realization method and process of car insurance sales system based on ASSF, on this account, it introduces the major work while developer using ASSF to develop system. Through the application, it validates the arguments presented in this thesis. Main features of ASSF are as follows:(1) ASSF is a perfect framework composed of client and server. Client and server are divided clearly. The core function of client is sending request, generating component dynamically, receiving data, display results; the core function of server is executing server inquiries and service location.(2) ASSF server uses algorithms of keywords extraction and stem extraction to process user request and candidate services, it extends the query algorithm based on single keywords supplied by Uddi4j, and realizes query algorithm based on vector space model to improve precision and recall of service.(3) ASSF client realizes Soap Services calling based on browser, and it parses Soap message to solve the issue of IE which can not parse Soap message correctly. (4) Client and server exchange data and client calling Soap Service uses JSON, compared with XML as traditional format of data exchange, it saves bytes of communication and improves the efficiency of the network.(5) Client imports file using CI mechanism, improving the effectiveness of the imported file. In addition, the client and server are configured independent to ensure the security of framework.(6) Server ASSF is developed by Java, client is developed by JS. Both of them are object-oriented. Therefore ASSF has good scalability.
