Is there a Spring Security OpenId Registration like stackoverflow?

Question

I cannot find a complete example anywhere of a Spring Security Web App with Open Id registration similar to stackoverflows.

I would say I'm pretty techy guy but I find Spring Security extremely intimidating with its weird Spring XML DSL.

I have found bits and pieces of how one would do the good ole' stackoverflow registration using:

• Spring Security Open ID sample WAR
• Hillerts Blog 3 part blog posting
• Spring Security Official Doc on OpenId (the email attributes are wrong see next link)
• Stackoverflow posting about email attributes
• JQuery OpenId library for picking your OpenId provider Stackoverflow has a modified one that seems to include Facebook
• Best Article on the subject but a little long winded
• Another example like previous one for Google App Engine

But no complete examples (WAR). Does anyone know or have a working example (ie WAR) that does more than just authenticate with an in-memory openid urls?
