Research And Application Of Web Application Framework Based On J2EE

With the increase of the enterprise need for software, the function of application system is stronger and the structure of software is also complex more and more. Software companies have to implement these complex functions. On the other hand, it must accomplish it mission rapidly in order to reduce cost and cope with the cruel competition. So it is one of the hot spots about Internet technology how to build a Web application system with strong functions and use flexible which can respond a large number of clients at the same time and run safely and stably.Now, J2EE are come to maturity day by day and used widely. More and more developers are using Web framework based on J2EE. Framework boosts hugely the rapidity and efficiency of Web development by ready-made soft packages. To develop a Web application base on one framework but begin from zero, it can shorten the time of development and reduce development risk and improve the stability of the application system.These days, there are many pop Web frameworks such as Struts,Spring,Hibernate etc. These frameworks are already very mature and have been used widely at in practice. But, the same problems to them are difficult to learn and grasp especial to those beginners at J2EE.WebFramework is born because above the reasons. WebFramework, based on the J2EE platform, is a framework implemented the MVC design pattern. The framework is made up by data tier, business logic tier and show tier. It is expandable, simply and run stability, response rapidly, maintenance easily. To develop a Web application system base on WebFramework can shorten development time, save cost and reduce risk.This thesis introduces the theory of J2EE first, then expatiate the design principle of each layer and sequence of run. At last, the thesis introduces briefly the process of developing the COSCO Shipping Management System according to WebFramework.
