After installing NetBeans IDE 7.1.1 get error: package does not exist

After Windows 7 was installed on laptop, I reinstalled NetBeans IDE 7.1.1. Re-copied in saved project. Try to build it but it seems like it can't find libraries:
warning: [options] bootstrap class path not set in conjunction with -source 1.5
C:\Users\V890607\Documents\NetBeansProjects\COPA_Survey\src\copa_survey\ConfigFile.java:18: error: package org.apache.log4j does not exist
import org.apache.log4j.Level;

C:\Users\V890607\Documents\NetBeansProjects\COPA_Survey\src\copa_survey\RemedyQuery.java:16: error: package com.bmc.arsys.api does not exist
import com.bmc.arsys.api.Constants;

This is a Java program that uses Remedy jars to access a Remedy database. I've placed the Remedy and other libraries in a library directory and stated the library in the CLASSPATH. I've also added it to the Compile-time Libraries via Add JAR/Folder.

This built fine before. Not a NetBeans expert so I'm thinking that I'm missing some simple setting.

Co-worker showed me that I had to do the Add JAR/Folder for each jar file I used and not just add the directory that contained them. That solved it.
