The system adoption B/S (Browser/Web) develops mode, developing a tool choice cross-platform, open type, safe function better Java language, adopting a Tomcat server technique, the backstage database chooses to use Microsoft SQL Server 2000.Three layers of system structure of system adoption'sâ†'JavaBeansâ†'SQL Server 2000 development, namely head from JSP web page realization performance logic, use JavaBeans module to carry out the system internal complicated business logic in the center, behind carry usage SQL Server 2000 databases carry out data logic.eThis text put forward according to the solution of Java on-line examination system, carrying out the special principle of topic classification: Examining a topic and trying a type, difficulty, score... etc. all can be made to order by managing person's(teacher) oneself.
