This image shows a simplified version of how the classes used for the Login page interact with each other using the Model-View-Control (MVC) pattern. The user clicks Log In; the Interpreter Servlet/Handler transfers the request to the Login Control; the Login Control passes Do Login to the Login Model; the Login Model passes the successful login to the Login Control; the Login Control redirects to the MyPage; the Interpreter Servlet/Handler gets the HTML from the MyPage View; the MyPage View passes the HTML for the MyPage to the Interpreter Servlet/Handler; the Interpreter Servlet/Handler displays the MyPage to the user.
