i've got problem with using java. i'm a student and we're told to use
microsoft's compiler and vm.
files are compiled using jvc (visual j++ compiler) and view files with IE.
i've got MS VM installed,
but also Sun JRE 1.50 and my IE even doesn't show initialisation
information in the file I
appended.
thanx for any idea.

Off the top of my head without actually
compiling and trying your code,
Have you added -depreciate to the
command line? That is pretty much
a necessity if you are going to use
Sun 1.1 or greater instead of M.S.
to compile.
