Struts Tiles Question in J2EE Project

Hi Folks,

okay, here we go with the problem, in my j2ee struts project i got a little problem:

tiles-definitions made in my <b>tiles-defs.xml</b> are not read / mentioned in sub-pages.

here is my code (in short form):

<b>struts-config.xml</b>

-


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

<b>tiles-defs.xml</b>

-


<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/tiles-config_1_1.dtd">

<tiles-definitions>

<definition name="base.definition" path="/jsp/layout.jsp">
	<put name="title" value="testtitle" />
</definition>
	

<definition name="page.login" extends="base.definition">
	<put name="test" value="test" />
	<put name="body" value="/jsp/login.jsp" />	
</definition>
</tiles-definitions>

<b>layout.jsp</b>

-


<%@ page language="java"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles"%>
	
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html locale="true">
<head>
	<html:base />
	<title><tiles:getAsString name="title" /></title>

	<div class="content">
		<tiles:insert attribute="body" />
	</div>

</body>
</html:html>

<b>login.jsp</b>

-


<%@ page language="java"%>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles"
	prefix="tiles"%>

		<div class="introtext">
			<h4>
			<tiles:getAsString name="test" />
			</h4>
		</div>

<b>My problem:</b>

-

Tags in layout.jsp are used correctly, but tags in login.jsp result in the failure-message:

<i>ServletException in:/jsp/login.jsp] Error - tag.getAsString : attribute 'test' not found in context. Check tag syntax'</i>

What am i doing wrong that the tags are not interpreted in the pages which inherit from the base definition?

Hi,

I wonder if maybe the error occurs because "test" in the page.login definition is parsed as a tile because page.login extends base.definition.

Title in base.definition does not because base.definition does not extend, so that's why getAsString works there.

If this is the case, moving 

<put name="test" value="test" />

to your base.definition section should solve the problem.

But it's just a thought.

Good luck, Roelof

thanks for your answer, no even if i define elements in the parental structure, i can't even display them on the *.jsp pages which are included via tiles themselves.

i think the problem just is that tiles-elements on those jsp pages, which are used in a layout themselves can't interpret the tiles-defitions.

it's just the question if i've got to modify the controler somehow or if it possible just not work
