Error pages are invoked when there is an uncaught exception from
within a particular page. In this case, we mention that the
<CODE>validationGaurd()</CODE> method might throw an exception.
If this exception is not caught within the page, then we vector
control to the <CODE>errorPage</CODE>, as stipulated in the attribute

<P>This quiz used the <I>Page-View with Bean Approach</I>, detailed in <A
HREF="/developer/Books/javaserverpages/">Chapter 12, JSP Archeticure</A>. The <A HREF="index.txt">first
page</A> of the quiz consists of regular HTML with a form that calls <A
HREF="answer.txt"><CODE>answer.jsp</CODE></A>. <CODE>Answer.jsp</CODE> requests parameters from the bean,
in this case, called <A HREF="QuizResponses.txt">QuizResponses</A>. The <I>page-view with bean</I>
approach for this quiz required extra work to write the bean, and it could have been done using the
<I>page-view approach</I> without a bean, requesting invocation directly from the <CODE>answer.jsp</CODE>
page. Deciding which approach is preferrable depends on the application and how much HTML and Java
scriptlets need to be used. For this quiz we opted for the <I>page-view with bean</I> approach for
illustration purposes.
