Design and Realization of Network Test System Based on J2EE Architecture

To the requirement of paperless examination, we develop a three-layer network test system based on the platform of J2EE and SQL Server2000, which is designed with the mode of JSP/Servlet/EJB, and the running environment is used Tomcat virtual machine. The examination system also adopts transaction management function to protect the database security. The examination system can randomly select questions to create a unique examination paper for every student, and also automatically mark paper by computer. The experiment demonstrates: the network test system is high stable and dependable, and can adapt large scale examination, which can highly lighten the workload of teacher, and raise the efficiency of examination papers treatment. Those merits make the network test system possess good practical value.
