J2ee-based Enterprise Application Framework For Research And Application

At present, J2EE-based Web application has become an important field of enterprise-class web application. Though the emerging open source framework have highly promoted the efficiency of developing J2EE application,they are only the frameworks for a certain application layer, not for all the application layers.The application framework is a reusable design of a system and a template for building an application. Essentially it is an abstract implementation of a set of design patterns and offers some infrastructure services.This paper described the problems on developing J2EE web application Frameworks,integrated such open-source framework as Webwork, Spring, Hibernate, Log4j, OSCache together, designed and implemented a J2EE enterprise application framework, which using a variety of architecture design patterns (such as multi-storey structure, MVC patterns, IoC pattern, etc.) to ensure that the procedures are loosely coupled and easy scalability, and provided an effective mode of application development, By which, developers can be directly based on the framework for efficient application development.With the framework applied to the HuNan Provincial Department of Health project "a new type of rural health care management systems, Edition 2008 ",Which is designed mainly by Webwork+Spring+ Hibernate.Front page using Ajax a new technology Extjs which provides a consistent layout model and interactively.Application framework based on the pattern of development, developers do not have to concern about the complexity of the basis of the framework, only need to focus on application business logic to achieve a sound business logic to adapt to changet.
