Design And Implementation Of Web Second-Development Platform Based On J2EE

With the widespread use of Web technology , many enterprises urgently hopes to build their own Web business Systems . Although these Web business systems seem different owing to the special business, they are approximately similar according to the view of software developers. It becomes very important for software enterprises to reduce technical redundancy work and improve the software productivity.A fundamental solution is to develop a general Web second development platform which shields the technical detail of implementation and causes a standard software process.With it, much attention will be paid to the analysis and implementation of Web business system.The software architecture is focused on what components should be used to set up software system and the relationships between these modules. This article analyzes the evolution of software architecture and points out both merits and dismerits of each of them .It emphatically analyzes the popular multi-layer software architecture and B/S architecture. Then it expounds the J2EE standard used in developing enterprise level application system based on multi-layer software architecture and related technology contained in it. This article also summarizes the current popular object-oriented method of software development and object-oriented unified modeling language --UML and makes the outline of design patterns.Focusing on the Web business system, this article elucidates how to design and implement a Web Second-Development platform(to be called WSD) based on J2EE by virtue of MVC design patterns and UML. Finally it illustrates how to use WSD to develop a special Web business system step by step.
