This section provides two examples of extending the default security model and an example of authenticating a user:
Extending the Standard Security Policy
The first example shows how to deny access if the access control list is null. The second example shows how to deny access except during specified hours.
Authenticating a User
This example defines a bean and associated form that presents a login form to a user until their login succeeds, then lists some details about the account they logged in with after the login is successful.
