With the prevalence of mobile phone and development of wireless, Mobile e-commerce will be a new e-commerce mode in the electronic commerce realm, and it is very promising. It can be predicted that the mobile e-commerce will become the major industry of e-commerce in the 21st century. J2ME is the platform that provides the JAVA language to develop the embedded electronic equipment of expense, which aims at the equipment that resource is limited. Therefore the interactive information exploitation developing with network server and applications of wireless terminal development based on J2ME platform is very important. It is a general method to implement the system of e-shop using three layers of pattern: client side + Java servlet + database of SQL Server. All the business logic encapsulated in the servlet, using of the database improved the security, and using the XML data format achieved cross-platform data exchange. To the system demand analysis, the system requirement analysis, the overall of system construction and the detailed design are elaborated in details in this paper, and the system achieves the following functions: Member registration, log
