I am using spring 3 + Tomcat 7
In web.xml
I have defined
404
I am not sure whether giving the direct url in location will work. But you can put a jsp there and redirect to the url from the jsp.
<error-page>
<error-code>404</error-code>
<location>/filenotfound.jsp</location>
</error-page>
filenotfound.jsp
<%@ page language="java" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<c:redirect url="http://hotmail.com" />
