Cannot resolve Tag Library

I am using *IntelliJ 3 *for my JSP/Servlets and Struts__ application. I have my application directory structure as follows:

C:\webapps --> home directory for my application
C:\webapps\src\books\*.class
C:\webapps\WEB-INF\lib\struts.jar
C:\webapps\WEB-INF\struts*.tld
C:\webapps\WEB-INF\web.xml
C:\webapps\*.jsp

In my JSP Page I have a tag:
<%@ taglib uri="struts-html.tld" prefix="html" %>
and the editor says "Cannot resolve Tag Library__" wonder why!

Later after reading many Forums here on similar topics I added *EXTERNAL RESOURCES *to my IDE Settings:
URI: struts-html.tld
Location: C:\struts\lib\struts-html.tld

But still I am getting the same errors wonder why... I have been trying all possiblilities since last 2-3 hours but in vain... Can any experts here help me out...?

THANKS!
