Implementation of a WebDAV-Based Collaborative Distance Learning Environment

摘要

In this paper, we propose a new approach for constructing Collaborative Distance Learning (CDL) environemtn utilizing the latest IETE specification: WebDAV. As a Web-based groupware in nature, this CDL environemtn enables distance learners to accomplish most of scademic collaboration activiteis that are needed in a virtual university directly on the Web through standard Web browsers. Besides WebDAV, an enterprise-level platform: J2EE is adopted as the foundation oft he CDL environemtn in this approach. It ensures the scalabiloity, extensibility, and openness of the system facilitated by sets of J2EE technologeis, e.g. EJB, JavaBeans, and JSP, etc. We then introduce a prototype implementation of the CDL environemtn called "Collaborative Desk". "Collaborative Desk" will be applied as an important way for supporing collaborative learning in a virtual university.
