Newbie question - on syntax error

I am completely new to java so bear with me.

I am working through the netbeans tutorial
(http://www.netbeans.org/kb/docs/java/javase-intro.html) which has me create
two packages: pasted below.

I am getting a syntax error: "cannot find symbol: variable LibClass". The
code is pasted directly from the tutorial so it should be accurate. I
suspected that the environment can't "see" LibClass because soemhow I
screwed up adding the other library to my application. However, when I use
Ctrl-space to do code completon on ibclass.acrostic it shows me the package
and method definition. This tells me that the environment can find LibClass.

Can someone suggest what I might have screwed up? It sucks to hit a bick
wall so early in the tutorial process.

Thanks,

Steve

package acrostic;

public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
  String result = LibClass.acrostic(args);
  System.out.println("Result = " + result);}}

package org.me.mylib;

public class LibClass {

 public static String acrostic(String[] args) {
        StringBuffer b = new StringBuffer();
        for (int i = 0; i < args.length; i++) {
            if (args[i].length() > i) {
                b.append(args[i].charAt(i));
            } else {
                b.append('?');
            }
        }
        return b.toString();
                }
}
