/*  A simple JavaBean to hold a message. 
    This bean will be used to transfer a text
    message between the Controller Servlet and the JSP view.
    By using this mechanism, we can put a little bit of logic 
    into a JSP page and only need a single JSP page instead of 
    multiple ones for responses back to the user.
