Okay, I found some of the problem.  I wrote:

This, of course, does not work because the .java file has not been
compiled into a .class file.  Unfortunately, the README file says that
this should work.  Perhaps the next release will add the compiled
HelloWorldApp.class file to the test directory so silly people like me
don't get confused.

I made a compiled the .java file on another system and then tried to
run it and it worked fine.  So the interpreter/JIT seems to be okay.

Next, I tried compiling and that is still broken.  I reinstalled
everything and I still get these errors.  Any further suggestions?
It kind of looks like I don't have something installed, but I
installed all 4 .tgz files.

Thanks,
