Design And Implementation Of Distance Education System Based On J2EE

Internet and Web technology development for modern distance education provides a new education method and technical support. Based on the Internet by constructing a modern distance open education teaching environment, overcome traditional education in time, space, restrictions, and for effective play all kinds of education resources superiority, realize reasonable allocation of resources, development business education plays a very important role.Based on the present situation of distance education at home and abroad on the basis of study adequately, combining distributed applications in modern distance education technology and the teaching mode, based on the Web application MVC system, in the J2EE platform on design and implementation of a modern distance education based on the Internet support sys-tems. This paper discusses the characteristics of the technology multi-distributed architecture and J2EE, a model for system design of some key technology is studied. In system design, the method based on MVC Web application system. The JSP (View)+Servlet (Controller)+Java Bean (Model) system design effectively realized the interface design and logic programming of separation. This system as remote education of a support system, judging from the function, including the latest trends, notify the campus teaching management, teaching resources mana--geement, online exams test and course operation management, enrollment files management seven modules. Based on modern distance education in teaching mode of detailed analysis, the function of each module are classified, and the construction of the system makes a further discussion. This paper of modern long-range education system of online exams testing and enrollment files management to carry on the detailed design. Of the two parts of the key graph is given, and the key of the interaction process are given sequence chart, use case and the key part given realization. Finally, in system testing part of this system is also given a key part of functional testing and the functional test cases.This system as a rural school education system can meet all the teachers and students daily learning and teaching requirements, in put into operation in the year, reflects the good performance of the system, obtained the school teachers and students of superior leadership’s consistent high praise.
