 This JSP displays a login screen.  When the user fills out
 the login screen, it will submit it to the Login Servlet,
 which will verify the user's credentials by calling
 EJB components.
 
 if verification is unsuccessful, the login servlet will return
 the user to this page to re-enter his credentials.
 
 if verification is successful, Jasmine's main page will be
 displayed.
