基于J2EE的网络考试系统的设计与实现

针对无纸化考试的要求,开发了一套基于J2EE标准的三层模式的网络考试系统,它以JSP/Servlet/EJB方式工作,其运行环境采用JBOSS结合Tomcat,并启用了事务管理来保障数据库的安全。其重要特点是随机出题,机器阅卷。实践表明:该系统稳定可靠,能适应大批学生同时考试,并显著降低教师阅卷负担,具有良好的实用价值。

DESIGN AND REALIZATION OF NETWORK TEST SYSTEM BASED ON J2EE

Aiming at the request of no-paper-examination,we develop three-layer network test software based on J2EE,which run in the mode of JSP/Servlet/EJB,it's running environment adopt the JBOSS to combine the Tomcat,and use the transaction management function to guarantee the safety of the database.It is the software's important characteristics that selecting questions in randomly and grading examination papers by machine.The practice demonstrates: the software is stable and dependable,it can adapt a large quantity of students examine at the same time,and can vastly lighten the burden that teachers grade examination papers,and also have good practical value.
