     That's a problem.  I guess what I can do is change the "archive"
attribute to accept either a URL or a path name, then change bootstrap.xml
to read archive="${npsnetv.home}/archives/resource.jar".

     Thanks!  I'll put them in the CVS repository.

     They're basically all very simple tests.  If they don't generate error
messages and nothing too bizarre shows up in the window, then they're
probably working.  The "jspi" tests won't work at all in Linux, however;
they rely on the Elumens drivers, which are only available for Windows and
Irix.

     That is strange.  Hopefully in the future we'll be able to get a Linux
box up and running here to work on some of these issues.
