I've used Tiles in the past. Started to implement it in this new app,
and I keep getting error messages like...
javax.servlet.jsp.JspException: Error - Tag Insert : No value found
for attribute 'header'.
at
org.apache.struts.taglib.tiles.InsertTag.processAttribute(InsertTag.java:690)
at
org.apache.struts.taglib.tiles.InsertTag.createTagHandler(InsertTag.java:478)
<snip/>
Basically it seems as if none of the attributes I define in my tiles
definition file are being able to be picked up by the main layout. I'm
hoping someone can pick up something that I'm doing really dumb here.
Here's some info..
Tiles Definition
---------------------
<?xml version="1.0" encoding="UTF-8"?>
<!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="main.layout" path="/mainLayout.jsp">
<put name="header" value="/WEB-INF/jsp/header.jsp"/>
<put name="content" value="yrdy"/>
</definition>
<definition name="main.page" extends="main.layout">
<put name="content" value="/WEB-INF/jsp/main.jsp"/>
</definition>
</tiles-definitions>
(files header.jsp and main.jsp exist. mainLayout.jsp displays fine
also when I remove the tiles:insert sections.) I've also tried the
above 1_3.dtd defintion, but I think that gave me other problems. I
know the above 1_1 version was working in another app that I believe
had my 1.2.7 struts jar.
mainLayout.jsp
---------------------
<%@ taglib prefix="tiles" uri="http://struts.apache.org/tags-tiles"; %>
<---- snipped out extra html junk ----->
<body>
<div id="contents">
<tiles:insert attribute="header"/>
<div id="main-content-box">
<tiles:insert attribute="content"/>
</div>
</div>
Again, if I comment out the above tiles:insert lines this page will
display (minus the tiles content I'm trying to add of course).
struts-config
-----------------
The docs are a bit confusing on this, since in the docs it says you should add
<controller
processorClass="org.apache.struts.tiles.TilesRequestProcessor"></controller>
I've tried including and remove the above.
I also include the plugin definition:
<plug-in className="org.apache.struts.tiles.TilesPlugin">
<set-property property="definitions-config"
value="/WEB-INF/tiles-definitions.xml"/>
<set-property property="moduleAware" value="true"/>
<set-property property="definitions-parser-validate" value="true"/>
</plug-in>
Other thoughts
---------------------
I removed all filters that I have running, thinking maybe they were
mangling some request or session parameters.
The test i'm doing from the index page just has
<a href="authenticate.do">clickme</a>
And the action-mapping for it:
<action
path="/authenticate"
type="com.nielsenmedia.npn.action.AuthenticateAction"
>
<forward name="success" path="main.page"/>
</action>
The AuthenticatAction has been stripped down to simply return
"success" (It doesn't do anything).
I'm using Struts 1.2.9 but also tried some older jars like 1.2.7.
At 4:00 on a Friday I'm not happy that I can't get this basic Tiles
stuff working. Any ideas what I might be doing wrong?
Thanks,
Rick
