Unable to get RequestDispatcher for Context

Question

Eclipse 3.3.0
Tomcat 6.0.16
Java 1.5.0_13
Mac OS X 10.5.6
Greetings:
I'm attempting to retrieve information cross context in my web application. I've attempted to enable cross context access by three means.
- I've added "crossContext=true" to the <Context> element in the server.xml of the Tomcat configuration under the Servers project of my workspace.
- I've added "crossContext=true" to the <Context> element in a META-INF/context.xml in the WebContent folder of my project.
- I've added "crossContext=true" to the <Context> element of the context.xml file in the conf directory of the Tomcat installation directory.
Yet despite these changes I'm still seeing "Unable to get RequestDispatcher for Context....Verify values and/or enable cross context access" in the console. What do I need to do to enable cross context access using Eclipse? Thanks for any help.
ETA - I've had this working before. I believe that I upgraded to Tomcat 6 from Tomcat 5.5 and that's when the jstl cross context actions broke.
ETA - I've got it working in Tomcat 6. The problem arises when I change the name of my webapplication from "foo" to ROOT inside eclipse. I want a jsp page in the ROOT web application to be able to access a servlet in the "bar" web application.

Thanks for your reply evnafets.
How many times do you declare your context???I know, I know... I got frustrated. :o)
But seriously, since my post I've discovered that it is "working" but not in the manner I had expected within the IDE. That is, if I access the page at
http://localhost:8080/ROOT/myPage.jspThen I can see the contents retrieved from the context bar. But if I use.
http://localhost:8080/myPage.jspI can see that the page somehow has been deployed to the root context, but the error code 500 appears in place of where the content from the bar context should be.
However, if I export war files for these two web applications and run them in Tomcat 6 outside of Eclipse, everything works as it should. So this is an eclipse issue with respect to deploying a web application to the root context. Maybe there is some configuration about that I must make somewhere.
I hope that makes sense.
Anyhow, the server.xml file contains the following..
<Context crossContext="true" docBase="bar" path="/bar" reloadable="true" source="org.eclipse.jst.j2ee.server:bar"/>
   <Context crossContext="true" docBase="ROOT" path="/ROOT" reloadable="true" source="org.eclipse.jst.j2ee.server:ROOT"/>The jstl code in the jsp page accessing the context bar is the following.
<c:import url='/helloworld?action=view' context='/bar' />
