Research And Implement Of J2EE Based WEB Examination System

With the development of network education, the WEB examination system is more and more important for it, especially for electrical network education because of its complication.Currently, WEB examination systems applying to Internet are various, among which some essential arithmetic and function design is fairly perfect, for example, automatic paper making arithmetic, automatic grading arithmetic and so on. But there is no good mature solution to the software reusability, maintenance, distributed numeration and transaction, which are essential for a large WEB examination system. The paper puts forward a solution to these problems by using J2EE technology and J2EE design pattern, among which J2EE technology perfectly supports distributed object, transaction and database connection pool, the design patterns perfectly solve the problem of software reusability and maintenance.The paper is divided into 4 chapters, chapter 1 introduces the J2EE technology, chapter2 introduces the specialty of design patterns presently used, chapters selects appropriate design patterns for WEB examination system and is discusses the implementation of some modules.
