1、 I 摘 要 网络的蓬勃发展拓宽了人们的生活空间，也改变了一些人们的生活习惯，而 以前一些无法实现的事情现在也变成了可能。 传统的教育方式随着网络的发展正受到挑战，而网络教育开始受到青睐。究 其原因，主要是课堂教育方式受到一定的限制：通过教师在课堂授课得到的知识 毕竟有限，而大学教师一般都有自己的科研任务，课余时间也相对紧张，同时， 学生对知识的需求随着竞争的激烈正愈来愈大。基于此，我设计的这个在线教育 系统，实现了资源的共享，一方面减轻了教师的教学压力，另一方面解决了学生 知识需求的问题。 该系统采用 BEA WEBLogic 作为服务器，用 Oracle 9i作为后台数据库，而网 页设计主
