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

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

That's where your problem is then. You need to put it all in the default package or IconMaker needs to be in the GUI package. And you need to recompile and re jar it.
