The Research Of Wireless Electronic Commerce Based On J2ME&J2EE

The thesis studied the wireless electronic commerce system based on J2ME&J2EE,introduced the key techniques building enterprise's electronic commerce system,and analysed J2EE architecture and method implementing J2EE multilayer enterprise application.The EJB layer embedding business logic was deeply investigated,and the Web layer's key techniques Servlet and method accessing EJB was introduced.Because the thesis's keystone is the application of wireless terminal based on J2ME and the information exchanges with server,so the J2ME architecture,the method implementing network resource connection,and the process of implementing mobile Web service with XML were particularly analyzed.Security is another key element in the system,so it was also discussed in detail.According to the researching results,a wireless electronic commerce system based on J2ME&J2EE is built,and several functions for users are provided,which are figure validate,PIM,goods query and update with mobile phone, disposal status of order goods,and to table a proposal for company and so on.Sellers can query goods price and stock info in real time,and create,query,update,delete goods while having enough operating permission.Manager can manage goods depot, finance depot and human depot,and will implement data encrypt,safe authentication.The research has a wider significance.The system could not only be applied to the wireless electronic commerce system,but also could be extended to broader fields fields,such as CRM,SMS,online reading,mobile bank and game etc.Developing the wireless electronic commerce system,a company can effectively improve relationship with its users and manage the user's accounts,and can enhance remote cooperation to different regions,and also can improve correspondence with staffers,users,partners and among providing serve chains.With J2EE and J2ME,the system has strong retractility,common,and we can fleetly develop a strong secure, extensible enterprise wireless application.
