Among them, the online auction has become an important part of electronic commerce, is the focus of recent research. With the rapid development of e-commerce, e-government applications, and continuously improve the user requirements, development technology of the traditional e-commerce, especially online auction system development technology has exposed many shortcomings, which reduce the efficiency, the development costs, expand and maintenance difficulties, not for division of labor and other issues, limit the further development of the online auction system. The main work of this thesis is the research and design of the online auction application system of Web mode and JSP technology based on B\/S. This paper first introduces the background of online auction system, analysis and comparison of the mode of operation, the system characteristic and the development technology of domestic and international relevant online auction system. Then analyzes all kinds of Web application development technology hot spot in current advantages and shortcomings, weigh the advantages and disadvantages, focusing on the study of JSP technology selection and development. Then according to the application characteristics of Web put
