In this project, I'll try to outline a few different OpenID libraries that work on the JVM and I'll be using Scalatra as my web routing library and a simple User model to hold state. My primary objective has been integrating with Google Apps so that I can back authentication against a domain which Google Apps provides services for.

This project uses SBT 0.10.1 and Scala 2.8.1

SBT is included here, so just run

./sbt 

Then run the command

jetty-run 

Pretty straight forward to include, although there is a dependency on Google Guice for which I had to add a new repository.

To include the Google Guice repository

"Guice Maven" at "http://guice-maven.googlecode.com/svn/trunk" 

To include the dependency

"org.openid4java" % "openid4java-consumer" % "0.9.6"
