Jakarta slide is an open-source content management system from the Jakarta project, which supports the WebDAV protocol and the WebDAV ACL protocol. To access the resources managed by slide, users should be registered to Slide with appropriate access privileges. Unfortunately, as of now, it is very cumbersome and time-consuming to add users to slide, setting up access privileges on the resources for them. So, to support efficient administration of the slide system, it is desirable to provide administration tools which can simplify those administrative activities. As one of such tools, we developed an administration tool for the slide system named SlideAdmin. Using SlideAdmin, the system administrator can add or delete users and roles more efficiently. SlideAdmin is composed of JSP pages for the user interface and Java Servlets performing the related administrative logic.
