The Design And Implement Of Multi-Layers Web Framework Based On JavaEE Platform

Along with fast development and maturation of computer network technology, a multi-layers framework for Web development which can apply to JavaEE platform has already become the mainstream framework in Enterprise Use. Currently, adopt JavaEE technology to build up Enterprise Use appliacation system, the requirement complexity has increase higher and higher, the development cycle is more and more pressing, meanwhile the stability, safty, extensibility and maintainability also call for more stringent requirements. Thus, what should the developers do to fulfill the requirements such as enhances the developing speed, accomplish developing assignment with high-quality and high-efficiency within limited time?The first section of this paper discusses the current Web application developing mode and status quo, analysis and discusses the universality、good and bad points within it. On these bases, study and design a kind of developing framework CADF (Composite Application Develop Framework) which based on JavaEE standard to use for developing mulity-layer Web application system. CADF framework made good abstract and transparent package to support application component, work flow magagement, system security, log management and data persisted. The main intention is to explore if it can provide a general solution to every difficult points in Enterprise Us developing, at the same time, also provide a Flexible scaling, High reliable and highly scalable performance JavaEE Enterprise application framework.
