Research Of Web Application Based On J2EE Platform

In recent years, J2EE(Java 2 Platform Enterprise Edition) platform has increased quickly. It has been the factual standard and criterion of developing enterprise application. The platform is an uniform set which is made of APIs(Application Programming Interfaces), service and protocols.The set includes the characters and functions ,which are needed in construction of distributing and more-layers application;In addition, the set provides vigorous and stable services todevelop and configure enterprise application.By right of its characters of strong migration and easy expansibility, the J2EE platform has gained the wide attentions from the most developers of Web application. During developing enterprise Web application, the combining of the J2EE platform and Web technique has become the mainstream trend in Web technique development currently.Apache Struts is one of the most excellent application frameworks which are used to implement the design patter of MVC .Struts not only provides: its own controller component, but also conforming some correlative techniques to implement model component and view component, which are all components of MVC design pattern.The research purpose of this thesis is implementing a data operation framework based on J2EE platform to increase the developing efficiency and solve the problem of over integration of the web tier and business tier.Firstly, this thesis carries on in-depth analysis to J2EE and relevant technology, focusing on J2EE structure, application component, container and the service technique. It also discusses EJB and J2EE design pattern in detail especially and introduces the struts framework which implement the MVC pattern in web layer.Then points out the drawback of system developing using struts and EJB. To these drawback, this thesis put forward a data general operating framework and suggested the design and implement process of the framework. Finally, introduces how to apply the framework into the developing of a real management information system.
