Web Application Research Based On Struts Framework And J2EE Platform

Traditional Web Application System have some weakness: low reusable of application, heavy maintenance work and weak adaptability of software. In order to improve the efficiency of web application development, expansibility and maintainability, it is urgent to use excellent platform,design pattern and system framework, which will be taken as a feasible scheme to resolve these problems.At first,this paper expatiates the J2EE platform. The platform is a uniform set which is made of APIs , services 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 to develop and configure enterprise application.The paper takes deep research in the MVC design pattern and Struts framework. The core thought of MVC is separating the representation logic, control logic and business logic of web application, so the loosely coupled system can be achieved based on this thought. Struts is a Java web application development framework based on the MVC design pattern, Struts framework can implement the representation layer and the control layer of web application, the model layer can be achieved by EJB3.0 components.After compares and analyses the Web application development architecture base on the B/S model,the paper brings out a Web application framework based on MVC design pattern which combines the Struts and J2EE platform.The paper takes a network book-shopping system as the combination of theory and practice,it implements the Web application exploitation framework which brought out by the paper.the paper details the implementation process from the representation layer and business logic layer.At last,it discusses how to deploy the system.
