I am working at a tiles application. When i use the tiles tag insert it is not recognized for . I get a warning like this: Unknown tag (tiles:insert)

My jsp page looks like this:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO 8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>
        <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
        <html>
        <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
        </head>
            <body>
                <table border="1" cellpadding="2" cellspacing="2" align="center">
                    <tr>
                        <td>
                            <tiles:insert attribute="body" />
                        </td>
                    </tr>
                </table>
            </body>
        </html>

I am using Struts2 also but those tags are recognized. my web.xml:

Am i missing something?

It was a version problem. Correct was to use: <tiles:insertAttribute name="body" /> not: <tiles:insert attribute="body" />
