error at import package with struts 1.3.8

[Yessica Brinkmann]

Hello.
I am using Struts 1.3.8 with NetBeans IDE 6.7.1.
In my code i import a struts package writing:
import org.apache.struts.action.*;
When I try to built my application i have this error:
package org.apache.struts.action does not exist
I have the struts library for the 1.3.8 version, I found the jars for this
version included at the NetBeans IDE.
This is my first application with struts.
Can the list help me please?
Thanks
