Compiles, but showing up "NoClassDefFoundError". Successfully compile and run for other programs.

I "dir" 'd the dir and the class is showing up...I tried compiling and running another program, which worked fine. I restarted MS-DOS and it did the same thing. What is going on?
Thanks,
cc11rocks

EDIT: I tried to run it from a JAR file. No go.

EDIT2: Getting different output now:

Could not find the main class: MyJoglCanvasStep1.  Program will exit.

Could it be I have to put it in a package?
EDIT3: The package was the problem.

The command java MyJoglCanvasStep1.java will look for a class named java in the subfolder MyJoglCanvasStep1 declared to be in package MyJoglCanvasStep1. Take it from there.

edit: per your EDIT2, the class has been declared to be in package net.sf.breed.mini.jogl.article; Either place it in an appropriate directory structure or remove the package declaration.

Note that the class may have dependencies which also depend on being in the correct place in the filesystem.

edit2: ok then

The first line of the code (I'm trying to figure out JOGL) said "package ******** blah blah blah". My bad that I didn't see that.

Thanks for the help,
