Design And Implement Selecting Courses Based On J2EE

With the development of network technology, many enterprises build enterprise-scale information applications based on Internet. As one of the most popular distributed computing platforms, J2EE technology has become a core part of enterprise applications based on Web. But J2EE itself is an enterprise-scale solution of wide comprehension. The appearance of all the new technologies bring the new opportunity to the application of J2EE Web, meanwhile, it also raise the biggest doubt to engineers, that is, how to select from all technologies and establish system framework, according to the requirement of the project and considering all the factors, such as the role division in the course of development, the management and maintenance in the anaphase and the expansibility of the systems, and so on.Meanwhile, multi-tier J2EE architecture improves the reusability of software and decomposes the complexity of problems, but it also makes the number of codes larger and the control relationships between tiers more complicated. Then the people abstract the same solutions to similar questions, and make those abstract solutions into frameworks. The frameworks with good reusability, well expansibility, excellent testing records have become more and more popular.Starting from the angle of system framework, base on a wide reference of relevant researches at home and abroad, the thesis gives a study to how implement MVC in JSF and Strategy of ORM.. It is analyzed to how to create Entity Bean, Session Bean and Message Bean with EJB3.0 which based on Annotation and discuss the application scope and their advantages and disadvantages of JSF and EJB3.0. Then, this thesis discussed that how to effective integrate JSF and EJB3.0 to build J2EE application. Through studying and practicing on main technology of JBoss Seam, this thesis provided a light framework of J2EE based on JBoss Seam in which JSF and EJB3.0 can effective integration. By means of practice of selecting courses system, the theory of this solution is carried out and the technical problems in the course of development and application are well solved.The research result in this thesis shows that the development framework of J2EE Web based on JBoss Seam+JSF+EJB3.0 has an excellent feasibility and practical values. The critical technology in the course of development provides a high-value reference to JBoss Seam+JSF+EJB3.0.
