William Billingsley ( whb21 at cam.ac.uk) has written a Raven valve for Tomcat based on the Raven Java Toolkit. It is available as Java source, in a .jar archive packed with a copy of the toolkit and as a github project.

He writes:

"I had to write this quickly for one of our servers. I'm sending it to the list because presumably others might need one too, and when I emailed Jon Warbrick in September he didn't have one. Alpha quality, but seems to work for me.
"source and jar attached. JAR also includes the webauth toolkit classes from the Raven project site so you can just drop it into server/lib and configure the valve in server.xml
"works for Tomcat 5.5, probably won't work for older Tomcat versions".

The valve is distributed under the terms of the GNU Lesser General Public License.

Installation

These instructions are for Ubuntu/Debian and tomcat6, alteration may be required for other OSes/tomcat versions

  • Add webauth.jar and webauth-tomcat.jar to /usr/share/tomcat6/lib/ probably by symlinking to the jar which is stored somewhere more sensible like /usr/local/share/java/ or if you have done pom to deb conversion (untested) then they should be in /usr/share/java/.
  • Install raven_pubkey.crt into /etc/tomcat6/
  • Modify /etc/tomcat6/server.xml to add the following to the relevant Engine
      <!-- Use the raven valve to restrict access -->
      <Valve className="uk.ac.cam.ucs.webauth.tomcat.RavenValve"/>
