WorkRoll is a Web-based bug tracker. It includes a Windows installer, or can be installed into a J2EE JSP container/Servlet engine via a WAR file. No database is required. Installation and use are fully Web-based. Features include sorting, filtering, file attachments, tiered access, email notifications, and import/export.
