Error encounter when using tiles on JSP
Greetings,
i tried to use tiles and tld files on a jsp page,but i encounter an error
while trying to load the jsp file.
These are the libraries i insert into the WEB-INF/lib folder
struts.jar, struts-tiles.tld, struts-nested.tld, struts-logic.tld,
struts-html.tld, struts-bean.tld, struts-el.jar, struts-bean.tld, jstl.jar,
c.tld, c-rt.tld
My jsp which i'm using:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles"%>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%><head>
<!-- Enter css here -->
<script language="JavaScript">history.go(1)</script>
</head>
<html:html locale="true">
<table width=100% border="0" cellpadding="0" cellspacing="0"
style="margin-top:0px;margin-bottom:0px"><tr><td>
<tiles:insert attribute="header" />
<tiles:insert attribute="body" />
<tiles:insert attribute="footer" />
</td></tr></table>
</html:html>
The errors i encounter:

Hi, newbie-gero
I remember that it should be using the name attribute
