Hi,

 The definition from the tiles file are stored in the factory.
 You should use the following to insert a definition:
<tiles:insert name="admin" />


the above method of trying to insert the predefined defs results in the following exception when I try to view the page.

So you have an error in your config or in your definition declaration.
Please, check the examples in the tiles-documentation.war. You can also check one of the following articles:

Check the tag syntax :-)

Here's the first few lines of the root cause of the exception I'm getting:

Here's my web.xml entries:

 <taglib>
   <taglib-uri>/WEB-INF/struts-tiles</taglib-uri>
   <taglib-location>/WEB-INF/struts-tiles.tld</taglib-location>
 </taglib>

Here's my struts-config entries:


<plug-in className="org.apache.struts.tiles.TilesPlugin" >
<set-property property="definitions-config" value="/WEB-INF/tiles-defs.xml" />
<set-property property="definitions-debug" value="2" />
</plug-in>


Here's my tiles-defs.xml entries:

<tiles-definitions>
<definition name="admin" path="/admin/templates/backendMain.jsp"> <put name="page-title" value="QuatraData :: Default" />
<put name="logo-content" value="/logoDefault.jsp" />
<put name="menu-layout" value="/menuBar.jsp" /> </definition>
</tiles-definitions>




Here's the page I'm trying to use the template in:

<[EMAIL PROTECTED] contentType="text/html"%>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<tiles:insert beanName="admin" beanScope="request"/>

( what I'm trying to do is just have a page that uses all the defaults specified in tiles-defs, that's why I have no put tags )


Here's the template itself:

<[EMAIL PROTECTED] contentType="text/html"%>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<html>
<head>
<title><tiles:getAsString name="page-title" /></title>
<script language="Javascript">
function launchTimeClock(){
window.open( "./timeclock/timeClock.jsp", "puchClock", "resizeable=no, height=170, width=230");
}

       </script>
</head>

<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" bgcolor="#CCCCCC" onLoad="launchTimeClock();">
<table cellspacing="0" cellpadding="0" border="0">
<tr>
<td width="300">
<!-- Logo Content -->
<tiles:insert name="logo-content" />
</td>
<td valign="top">
<tiles:insert name="menu-layout" />
</td> </tr>
</table>
</body>
</html>



Here's the pages that should be inserted:

logoDefault.jsp:

I am a logo

menuBar.jsp:

My Menu Bar




If I don't use definition, if I just use a template and then manually use tiles:put, it works fine.

Any help would be great, I can supply any other requested information.
