Note that the session attribute name used to retrieve the UserManager is the name of the managed bean. The class is annotated with Configuration which indicates that the class can be used by the Spring IoC container as a source of bean definitions.

  1. I was thinking of scanning a list of users already logged in held in an application-scoped bean and then denying access if the account is already logged in - BUT it is very simple for someone to lock themselves out for 30 mins that way! Can I instantiate it in my listener if it doesn't exist yet?

  2. Any existing binding with the same name is overwritten. My plan is to use a HttpSessionListener that will add the session to an attribute of the ServletContext which as I understand would mean it would then be application scope when the session is created.

  3. When you want to secure a webapp, you set up the basic security rules in web. As for examples, check any good book on JSPs and Servlets and you should find some information on setting up secured transport and container security.

  4. In addition, a Logout button is available which allows a user to invalidate the session.

  5. I'm creating an app with custom security and I want to make sure that there will only be one session per account at a time or one session per account if it's an privileged account of some sort.
