The Research And Realization Of Electronic Finance Based On J2EE Platform

in recent years, the new-style commercial pattern of electronic financial services, which is not only a simple application of Internet in commerce but also a new transaction pattern, has been drawing attention from all over the world. Its popularization has changed the traditional old transaction form, bringing about a new economic revolution. Fierce challenges are posed on traditional web technology by the development of electronic finances. The inside logics of electronic financial system being complex, the security requirements being rigor, and commercial patterns being in rapid changes, web technology is supposed to provide enough complexity and flexibility to meet the requirements of electronic finances.J2EE(Java2 Enterprise Edition) is a complete set of enterprise application standards and criteria based on Java, which was brought out by Sun Microsystem. J2EE boasts the peculiarities of trans-platform mutual- operation, expansibility and first-rate security, its object being to provide enterprise application system with a safe platform of irrespective bottom, transplantability and simultaneous access. On this platform, multilayer distributive enterprise application combined with Internet technology could be established easily and swiftly. Therefore, J2EE has obtained extensive support from the industrial circle in the past few years".MVC(Model-View-Control) is a design model brought forward for the logical programming language Smalltalk-80 by Xerox PARC in 1980's. MVC realizes the separation of operation logics and interface displaying in theory, it bringing great significance to the application development of web. Carrying out the web application development of JSP/Servlet+EJB with MVC is a prominent and unparalleled advantage in constructing electronic financial services.This paper illustrates several distributive object technology by contrast, introducing the software developing model based on modules framed in J2EE system and on this base eliciting the MVC software developing thought. This paper lays emphasis on the combination of J2EE and MVC, putting forwarding an enterprise application developing solution based on J2EE and MVC, which not only realize distributive computing easily, but also enhance developer's efficiency usefully. Finally, it uses this solution to realize a virtual online self-service banking system and takes it as an example to illustrate the specific steps and technical details of its development. This system is of clear design , strong modularity, nice expansibility and fine retractility.
