Web-application Development Based On Java Framework

In the rapid development of J2EE development, various technique frameworks and design modes are emerge in endless. Each technique has its own pros and cons. Nowadays none of them is in the master position. So the questions coming out to the surface that how we can implement our application software more effective in capability and expansibility, and not relying on certain implementation technique. Meanwhile, when we establish enterprise applications, we should consider that how we can combine various technique frameworks to use it more efficiency with their advantages. For developers, Web Application Framework provides a set of web application frameworks and a set of components for logic procedures. It is simplify development procedures and increase development efficiency. Development efficiency and difficulty are the core problems for web applications. So the goal for Web Application Framework is to simplify development and increase efficiency. The long term goal for Web Application Framework is to provide entire powerful development platform based on Java. In this dissertation, contents as following: Firstly, it based on Web Application Framework researches and characteristics of Java language, and from the angle of Java Web development, depicts the significant role that Framework played in enterprise Web application development. When modeling enterprise applications, a good technique framework can consider various technologies; it can choose the suitable ones with actual situations, meanwhile, it provides an environment that different techniques can used together with no conflicts. It can reduce project costs and increase development efficiency. Secondly, it analyzes the Web development framework development procedures. From simple model 1, to three layers, and even multi-layers'MVC model, this dissertation gives detail depiction. Based on the framework, it depicts Web development frameworks, principles and advantages for stable frameworks with examples. Following, this part is the main body of this dissertation. Nowadays, many development frameworks come out with their own usage. This dissertation gives most popular Web Framework, such as JATO, JSF, WebWork, WAF, including framework introduction, advantages, disadvantages and work principles for each framework. Based on above, case study on SAMS(Software Application Management System)project is used as an example for implementation, which detailed analyzes the project development with implementation internal enterprise JAVA development framework JTR. It begins with introductions to JTR framework, depicting that JTR is an application framework with main objective to reduce the variances in JAVA development, so developer can implement the application in an entire application model to realize the client's requirements. After that, it gives the processes on how JTR framework is used for implementation, including JSP web-based files, 5 types of Java files, two configuration files, and database add-on lists. It detailed depicts the areas including the function analysis, data analysis, JSP file design, Java file design, two configuration file modification and function points for testing and processes. It represents the characteristics and procedures under JTR application framework. Finally, it concludes the advantages and disadvantages for Java Framework under web application. Through a few types of Framework analysis and introduction and functions realization of...
