Actually the error happens in index jsp
<%@page contentType="text/html"%><%@page pageEncoding="UTF-8"%><%--<%@taglib
uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>--%><%@taglib
uri="http://tiles.apache.org/tags-tiles"; prefix="tiles" %>
<tiles:insertAttribute name="/baseLayout.jsp" flush="true">
<tiles:putAttribute name="title" value="Tiles Example"/> <tiles:putAttribute
name="header" value="/header.jsp" /> <tiles:putAttribute name="menu"
value="/menu.jsp" /> <tiles:putAttribute name="body" value="/body.jsp" />
<tiles:putAttribute name="footer" value="/footer.jsp" /></tiles:insertAttribute>
Somehow the insertAttribute tag is causing the issue.
Pls help.
Thanks Venu

My ultimate goal is to migrate an application to spring 4.1.4, Hibernate 4.3.
But this was resulting to migrate Tiles 1.x to Tiles 2.x. But this intern was
creating issues with Struts 1. With the help of Tiles user community, I was
able to get the struts-tiles2-1.4.0-SNAPSHOT.jar
library and I'm trying to migrate a small sample application from Strits
1/Tiles 1 to Struts 1/Tiles 2. After making changes according to the
suggestions in
https://feima2011.wordpress.com/2011/04/27/struts-1-and-tiles-2-integration/ ,
I'm getting the following error while running the application in the browser.

attach the ZIP of the application.
