摘 要 随着网络技术的发展和网络的普及，网络教学已经成为当前的一个教育热点。国家教育部根据当前的教育形式，适时提出了以建设“国家精品课程”为主要内容的“质量工程”，以实现优质教学资源共享，提高高等学校教学质量和人才培养质量。 本系统以JSP作为开发工具，使用SQL Server 2000作为数据库，编写JavaBean通用模块建设一个典型的基于WEB的网络教学平台，Java精品课程教学网站为学生提供一个网上自学该课程的环境，为教师提供了一个友好的教学平台。其中设计实现的基本功能包括：用户管理、资源管理、在线考试、师生论坛、资料上传下载、在线调查等，要使该网站功能完备，易使用，交互性强，还需完善的功能有：教学内容管理、网上答疑管理、考试管理等。 本文首先介绍了课题的研究背景、系统目标；结合系统的特点及实际需求，采用UML对系统进行需求分析，对系统的性能要求、工作流程、系统功能、数据结构等方面进行了总体规划；并对系统开发中的数据库连接问题、表单数据提交问题等提出解决方案。 关键词：精品课程；JSP技术；JavaBean；SQL Server 2000ABSTRACT Along with the development of network technology and the popularity of networks, online teaching has already been an educational hotpot. According to the present educational situation, the Ministry of Education, in time, put forward a quality project, with regards building of national choice courses as main content, to share the excellent teaching resources and to promote the teaching quality of colleges and the quality of talents cultivation. This system employs the JSP as developing tool, while utilizing the SQL Server 2000 as database, write the JavaBean general module to construct a typical online teaching plateform based on the Web, the choice courses teaching website of the subject of Java provides students with the conveniences of online self-learning, while the teachers with quality and efficiency. And the realization of basic function includes: the user management, the resource management, the online test, the teachers and students forum, material upload and download, the online investigation and so on, if want to make the very website a prefect, easy-to-use, high-interavtive one, must to consummate the function includes: management of teaching content, online replying management, testing management and so on. This article first introduced the topic research background, the system objective; Union the systems characteristic and the physical demand, use UML to carry on the demand analysis to the system, to systems performance requirement, work flow, system function, construct
