Login quickstart

Did I miss something or it has nothing to do with "login" in the sense of Realm and web security ??

Where's the use of JAAS or realms? How do I use container managed security? This example is not of much help, I already know how to implement EJBs and CDI beans. Anyone developing Java EE applications today should know that, and if not, this is not the place to show how it's done. I thought this was about Logins using Jboss security, please change the title it is missleading.
