Spring MVC -- The requested resource () is not available
===

I am working on a Spring 3.1 MVC application, and I have a JSP that is not rendering at all in my browser.  Instead, I see a message that says, "The requested resource () is not available."  Can anyone help?  This is GuestBook.jsp.

    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
    <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
    <%@ taglib prefix="myTag" uri="commentsTag"%>

    <title>Granada High School Class of 1986 Comment Page</title>
    <!-- Put a confirmation message here once you
         figure out how to do it with Spring -->
    <style type="text/css">
    p {
    	text-align: justify;
    }
    
    h1 {
    	text-align: center;
    }
