Presumably you aren't using Netbeans to run this jar file, though. So anything you wrote there about Netbeans could be considered irrelevant or even misleading
You need to look at what is actually in the jar now. Your command line argument, which I assume was the arguments for the "jar" command, doesn't appear to include your code in the jar. So have you looked in the jar? Are your compiled classes in there? And does it contain a manifest with a line which says "Class-Path: lib/jmf.jar"?
