[news.eclipse.newcomer] Cannot find the tab library descriptor? But it's

[laredotornado@xxxxxxxxx (Dave Alvarado)]

Hi,

I'm using Eclipse 3.4 on Windows XP.  I've created a web application 
project using a MyFaces 1.2 JSF framework.  Although the proper JAR files 
are in my project's WebContent/WEB-INF/lib directory, upon editing a JSP, 
I still see errors:

with messages like: 

Cannot find the tag library descriptor for "http://java.sun.com/jsf/core";

How can I clean this up?

Thanks, - Dave
