Research Of EC Application & Development Technology Based On J2EE

Under the environment of rapid development of international EC, it is a important topic how to promote EC development by utilizing advanced technology and ensure the security of EC according to our country's practice in China.From the reality of our country, the author considers that IT technology is the key to develop Chinese EC after analyzing the supporting factors, such as laws, certificate authority systems, electronic payment, logistic system and information technology. The basis of electronic commence is information technology, the basis of IT is software. For the convenience of system maintenance and cooperation development and improving the flexibility of software, three-layer or N-layer frame is often applied in practice, the various developing frames are summarized in the article. Because there are some obvious advantages, such as perfect running efficiency, reuse and crossing platforms, provided by the Java Technology basing on Java language, the EC developing technology basing on J2EE is becoming primary developing technology and hotspot, its basic theory and methods are summarized in the paper. Security is the key problem of EC, after introducing present secure technology and analyzing secure electronic payment models, the author puts up a secure electronic payment model basing on mobile payment confirmation.In the paper, for example, the author has analysed the EC transaction system of a trade centre of construction materials and made a plan for it.
