Well good grief! My problem was because I gave the java runtime program
the full filename (e.g. HelloWorldApp.class) rather than just
HelloWorldApp. Thank you for your help Mr. Green.

NoClassDefFoundError has so many different causes. I wish Sun would
find away to break that up into perhaps a dozen more specific error
messages or provide a tool to help you track the cause.

    NoClassDefFoundError pretty much accurately describes the problem from
the JVM's point of view (it couldn't find the class), and it's the JVM which
will trigger this error.

    What Sun could probably do is modify the "java" executable to print a
warning whenever you provide it with a qualified class called "class".

e.g.

@java HelloWorldApp.class
WARNING: Did you mean "java HelloWorldApp"?
Exception in thread "main" java.lang.NoClassDefFoundError:
HelloWorldApp.class
