A Design And Implementation Of The Network Examination System Of Students Based On J2EE

Computer technology has not applied to the examination, the organization at least have to go through a five-step test, and that of the candidates to test artificial markers, the results of assessment and examination papers. The workload of teachers will be growing, and its work would be a very cumbersome and error-prone things very clearly the traditional way of examinations has been unable to meet the needs of modern examinations. With the rapid development of computer applications, application constantly expanding, such as teaching and the emergence of virtual universities and so on, and these applications are gradually and families. People urgently require the use of these technologies for grading examinations, so as to reduce the burden on teachers and improve work efficiency, and at the same time improving the quality of the examination, so that the examination tends to be more civil, objective, and inspire students to learn more interest. For example, many international famous computer company run by the vast majority of the various certification exams in this manner. Therefore, the students of Web-based online examination system of great significance. Java language itself because of the openness of the system, as well as simple grammar, extensive domestic Java technology applications. Web-based application of key technologies and content mainly concentrated in the data access, data format conversion, logic control, data transmission, data such as that, and those are the advantages of Java, thus in the development of the schools through network connections a browser / server students use online examination system of projects, we have chosen the Java language and technology as a development platform.This paper introduced the "J2EE students online examination system" analysis, design and development of the whole process. UML language I use online examination system design process, detailed descriptions. Text adopted "students online examination system," said layer, service layer and data access layer design implementation, Spring on how to use the Web to test systems development, design, as well as Spring as a lightweight containers how to integrate with other frameworks , and other framework for how simple and effective non-invasive and integrated together. "The students online examination system" design implementation, verification and displayed a good lightweight containers of the non-invasive and reusability, scalability, and the development of high efficiency. This paper has also joined the Ajax technology, it is a creation of interactive Web application web development technology, it can use the server and some of the previous burden of the work shifted to the client, client to the idle processing power to handle, reducing bandwidth and server the burden, thereby saving space and bandwidth ISP rental costs. Subsequent testing, it also proves that the system to meet the functional needs, it is also strong and has high reliability and maintainability characteristics. The system realizes the Spring and Struts and Hibernate the perfect combination.
