Also to clarify, describing

java -jar jarfile

as expanding a jarfile is not quite right.  It works
exactly as you would run an executable.  On many
platforms, you can even just type:

jarfile.jar

on the command line or double click a jar icon to start the
app(*).  Not once do you have to worry about extra files
lying around.  In fact, it might even be the case that the
class files are loaded into the jvm straight from the
jarfile and not decompressed behind the scenes into a temporary
directory at all.


(*) That's why I think Web Start is a stupid idea that
makes people think Java is more complicated than it really
is.
