4、器发出请求，服务器对此作出响应，将有关信息发送给用户的浏览器。在B/S模式中，服务器上必须有所谓的Web应用程序，服务器通过运行这些Web程序来响应用户的请求。JSP正是一种优秀的Web服务器端开发技术，得益于Java语言，JSP具有跨平台、易维护和安全性，正适合用于在线考试系统的开发。本系统以软件工程方法学为指导并利用JSP技术设计实现基于JSP的网上考试系统，具有在线考试、即时阅卷、成绩查询及考题和考生信息管理等功能，开发工具采用MyEclipse，后台数据库采用SQL Server 2005。首先对系统的可行性及需求进行分析，接着进行数据库的设计、软件结构的设计，最后对前台和后台等进行详
5、细设计并在Myelipse平台下采用JSP技术编程实现。系统运行结果良好，达到预期目标。本系统的创新之处在于:第一.使用了Struts框架，Struts通过JavaServlet/JSP技术，实现了基于Java EE Web应用的MVC设计模式应用框架，是MVC经典设计模式中的一个经典产品，可以使得系统的设计思路更加清晰；第二.应用了EL表达式和Struts框架提供的标签库，大大减少了JSP页面中的脚本程序，使得页面代码更加简洁明了；第三.应用了Ajax技术实现考试系统的考试时间自动计时和根据选择的课程动态生成相关套题的下拉列表。局限于个人的开发经验，本系统尚有许多能够进一步改进和优化的地方，
6、例如JSP页面的布局和美化，过于简单的页面会使人觉得单调，但是过多的图片和不好的颜色搭配又会对用户的体验造成影响，还有代码算法的优化，因为编程经验的缺少，可能会使同样一个功能但是却付出了更多的资源代价去实现。不足之处，望各位批评指正。关键词：管理信息系统；考试系统；JSP；StrutsIIIINTRODUCTIONINTRODUCTIONWith the development of science and technology, the network technology has penetrated into peoples daily life.
