Design On J2EE-based E-Business Model System

With the rapid progress of Electronic Business, enterprise applications have to be designed, built, and produced for less money, with greater speed, and with fewer resources than ever before. Java 2 Platform Enterprise Edition (J2EE) Technology can do it well. It provides a componet-based approach to the design, development, assembly, and deployment of enterprise applications. The J2EE platform gives you a multitiered distributed application mode, the ability to reuse components, integrated XML-based data interchange, a unified security model, and flexible transaction control.With the example of the Electronic Business Model System that author take park in,we analyse its working principle deeply. Though design the work flow,we analyse its six functions such as B2B,B2C,C2C,net-banking,logistic center and CA. Though compare the Mircosoft .NET platform with SUN J2EE platform,we determine adopt SUN J2EE platform, and introduce core knowledge of J2EE. We design the authentication function and the track on line function with the help of Servlet. We use JDBC technology to establish link to Database,and apply Database Connection Pool to it, and it imporve the efficiency of accessing Database,also we give its instanse.
