【摘要】远程教育系统主要是针对成人教育中学生与教师相互分离、工学矛盾突出的特点而开发的。由于网速等原因
在学生的管理和学习过程中经常出现异常,为了提高访问速度,确保数据正确无误,采用基于 Ajax 技术的 DWR 和 Struts 相
结合的框架,实现浏览器与服务器的异步通讯,当页面上的少部分内容更新时不再需要传输整个页面的 HTML,降低网络数据
传输量,缓解网络压力。该系统已投入使用,运行良好,显著提高了学生的学习效率和管理质量。

【Abstract】The remote education system is principally developed for the mutual separation of adult-education
students and teachers, and for the prominent contradiction of work and study. Due to the speed and other factors
in the management of students and learning process, and in order to improve the access speed and ensure the accurate
data, the frame bination of Ajax-based DWR with struts is adopted, thus to realize the asynchronous
communication between the browser and the server. When little content on the page is updated, there is no need
to transmit the whole HTML of the page, thus to reduce the data transmission c
