Executing a JAR file under windows is typically done:
java -jar name.jar
Where name is the name of the file and you, of course, stand in the correct
directory.
Yes, I did exactly that:
cd "C:\Program Files\Java\jdk1.6.0\classes"
java -jar GUI.jar
To no avail, I still get NoClassDefFoundErrorThe CLASSPATH environment variable and the -cp command line option have
no effect when the -jar option is specified. Try compiling a simple
program from the command line and then run it. That should help you
find the problem.

I found out that apparently that's defined within manifest.mf, so here
is manifest.mf:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.6.0-b105 (Sun Microsystems Inc.)
Main-Class: GUI.IconMaker
Class-Path:
X-COMMENT: Main-Class will be added automatically by build

It appears Class-Path is undefined, or what does this mean?

email s/nospam/knute/Do you have a package problem? Is the main class GUI.IconMaker or
IconMaker?


The main class is called "IconMaker", in a "default package" that
remains unnamed by NetBeans, however, when it "jars" up the Main-Class
becomes "GUI.IconMaker". And yes, I tried both, to no avail. Again,
works beautifully on NetBeans on my machine at work, bombs completely
when I try to use it on the exact same setup at home
