Research And Design Of Enterprise Mobile Application System Based On J2ME And Web Service Technology

With the development of the third-generation mobile communication technology (3G) and the application of Web service in E-commerce, it has become a new research hotspot to develop mobile E-commerce system suitable to cellphone. Enterprises in our country are still very lacking in the application of mobile E-commerce, so it's of great significance to do some research and practical technology in this area to accelerate the further development of mobile E-commerce. This paper deeply researched on the J2ME and web services technology. Combined with the actual demand of mobile E-commerce in enterprises, it built a MSM system (mobile sales management), which update the marketing data in time and eliminate the dead information space.First, the paper introduced the JAVA platform and web services technology. Java has the strongpoint of "once program, running around". The paper developed the mobile application client supporting the Web services, which communicated with the Web services supplied by the enterprises.It helped to reduce the development costs of mobile information service system and improved the utilization of information resources. Based on this, it researched the integration of J2ME and web services, analyzed two integrated models of KSOAP and JSR172, and achieved the application of J2ME client access to web services using JSR172.Secondly,the paper designed and achieved the function of MSM system. This system aimed at the sales staffs of enterprises that got information of products and customers promptly anywhere, and could add or update customer information using cellphones. So the data of E-commerce system could be real-time supplemented. Sales staffs also could submit reservation of product and costs requisition asynchronously, which saved time and cost. The paper programmed to implement function of MSM system and introduced some details including implement and deployment of Web Service, access to database, clients'invoking Web services through JSR172, data access to mobilephone and implement of graphics user interface.Finally, after simulating and running, the performance and response speed accorded with the system requirement. It validated the feasibility of enterprise mobile application system which constructed by J2ME and Web service technology.This system realized communication between mobile terminal and the enterprise, which had certain commercial value.
