Jsp trial - nitrox reports tiles error

Question

Hi,
I just downloaded the nitrox trial version to use with Eclipse 3.0.1. I have a project that makes use of Java Server Faces and Tiles (an ibm sample from http://www-128.ibm.com/developerworks/java/library/j-jsf2/). To gain access to Tiles, I use the struts.jar and struts-el.jar libraries. I don't, however, use struts (i.e. there is no struts-config.xml).
I can build and execute the code under Tomcat 5.0.25 and it works fine.
The problem
Nitrox, however, reports the following error with index.jsp in the Eclipse Problems tab at the bottom of the screen:
"The tile ".index" cannot be found in the Struts tiles config files for this module."
I suspect that tiles-def.xml is not being found. If I rename tiles-def.xml to tiles-def-mod.xml, I still get the same index.jsp error.
Any idea why Nitrox is reporting this error?
Details
1. Tomcat-5.0\conf\server.xml has this line:
<Context debug="0" docBase="C:\MyProjects\eclipse\cdstore\WebContent" path="/cdstore" reloadable="true"/>
2. index.jsp and tiles-def.xml are located in:
C:\MyProjects\eclipse\cdstore\WebContent\index.jsp
C:\MyProjects\eclipse\cdstore\WebContent\WEB-INF\tiles-def.xml
C:\MyProjects\eclipse\cdstore\WebContent\WEB-INF\web.xml
3. index.jsp has two lines:
<%@ taglib prefix="t" uri="http://jakarta.apache.org/struts/tags-tiles" %>
<t:insert definition=".index" />
4. web.xml has:
<servlet>
<servlet-name>tiles</servlet-name>
<servlet-class>org.apache.struts.tiles.TilesServlet</servlet-class>
<init-param>
<param-name>definitions-config</param-name>
<param-value>/WEB-INF/tiles-defs.xml</param-value>
</init-param>
<init-param>
<param-name>definitions-parser-validate</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

I folowed your suggestions and added the struts stuff to my web.xml and placed an empty struts-config.xml under WEB-INF. I'm still receiving the same Nitrox error messages.
I intentionally removed the end bracket and changed the <struts-config> tag to <struts-config. Nitrox picked this up and reported the error.
When I made the same change to <tiles-definitions in the tiles-defs.xml file, Nitrox did not pick up the error.
My struts-config.xml file
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
</struts-config>
