This is a common error, as I have found from searching for a solution.
Unfortunately, I haven't been able to find anything that helped me fix
my problem. I'm running struts 1.2 on windows XP with Tomcat 5.5.7.

I've been working on this for a while, but haven't gotten anywhere. I
chopped it down to a minimum. index.jsp works fine unless there is a
tile reference, in which case it throws the exception.

I do have the tiles.jar file in my WEB-INF/lib folder. The taglib
location on the webpages is correct. The location of the
struts-tile-defs.xml file is correct in the plugin.

Here is what I have so far..

----> PLUGIN from struts-config.xml

<plug-in className="org.apache.struts.tiles.TilesPlugin" >
<set-property property="definitions-config"
value="/WEB-INF/configs/struts-tile-defs.xml" />
<set-property property="definitions-debug" value="2" />
<set-property property="definitions-parser-details" value="2" />
<set-property property="definitions-parser-validate" value="true"
/>
<set-property property="moduleAware" value="true" />
</plug-in>

----> JSP Page index.jsp...

<%@ page language="java"%>
<%@ taglib uri="/WEB-INF/tlds/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/tlds/struts-tiles.tld" prefix="tiles" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html locale="true">
<head>
<html:base />
<tiles:insert definition="page.default" />
</html:html>

----> struts-tile-defs.xml file entry for page.default

----> defaultlayout.jsp

<%@ page language="java"%>
<%@ taglib uri="/WEB-INF/tlds/struts-html.tld" prefix="html" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html locale="true">
<table border="0" width="80%">

</table>
</html:html>

What does the log file say when you start your webapp? Mine has:

12:35:42,050 - DEBUG org.apache.struts.tiles.xmlDefinition.I18nFactorySet -
Factory initialized from file '/WEB-INF/tiles-defs.xml'.
12:35:42,050 - INFO org.apache.struts.tiles.TilesPlugin - Tiles definition
factory loaded for module ''.
(Plus other lines listing all the tiles defs and their contents.)

Are you using modules? Looks like there's a problem parsing that config
file.

I don't think I'm using modules. Not sure what modules are...

I am thinking that this has to do with the ActionServlet method trying
to parse down either the struts-config.xml file or the
struts-tiles-defs.xml file, but so far I haven't been able to find any
problems with them. I am using MyEclipse to code and it sees no
problems with either xml file.

First, let me begin by noting that I work for M7. We develop NitroX.
The Struts version has very nice support for Tiles including design
time edits/views. One nice feature about NitroX is it's ability to
detect inconsistencies/errors that span the web app - at design time.
This includes the struts-config.xml, web.xml, java, jsp, tlds, etc.

Since you're already using eclipse, you can download the trial (get the
light version that doesn't include eclipse) have it point your eclipse
environment (or make a copy if it if you're worried) and see if NitroX
can automatically find the errors or provide some hints to the problem.

You can see some of the tiles support here:
http://www.m7.com/tiles.htm

You can download here: www.m7.com/free
I'd recommend the free JSP Editor since it includes trial capabilities
for the Struts IDE and JSP IDE. Remember to get the Express edition so
you don't download eclipse as well.

good luck.
