<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4"     xmlns="http://java.sun.com/xml/ns/j2ee"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">    <error-page>    <error-code>404</error-code>    <location>/building.jsp</location></error-page>
<error-page>    <error-code>500</error-code>    <location>/error.jsp</location></error-page>    </web-app>
