JAVA Servlet Library
This Java package includes everything necessary to write Java servlets that authenticate against Raven. It is released under the terms of the GNU General Public Licence version 2.
The Raven Servlet Library was written by Matthew Lavy and Alistair Turnbull, originally for CamCORS.
The Library is available as a github project
This library was lightly updated in June 2015 to support the Ucam WebAuth protocol V3 (and in paticular the ptags paramater in support of Raven-for-life), resulting in v1.0.3b.
