Google App Engine + Spring + Domain Object Instance Security

To the point, I was researching implementing security with Spring on Google App Engine which made me feel confident until looking at their implementation of domain ACL.

I was wondering if this would work in App Engine, and if there any resources/examples demonstrating a working 开发者_运维知识库application.

This is a bare bone example of Spring Security working on GAE, but without domain ACL, just basic authentication.

Thanks!

ACL just define a custom service, it have to work on GAE.

This should be a good start: http://grzegorzborkowski.blogspot.com/2008/10/spring-security-acl-very-basic-tutorial.html
