Are there user / role libraries for Java in the Google App Engine?

Question

To develop Java web applications in GAE, I would like to add androles user management. Is there a Java base library that provides role management (possibly based on annotation) that I could use as a basis?

Answer 1

Spring Security supports a variety of models, including role-based authentication. You can use the XML configuration as well as annotation-based ads, or even implement your own providers.
