Which file can you see? I don't see a file called test00.class in your jar,
which is the file that the classloader says it cannot find. Maybe my eyesight
is failing?

Oops. It's looking for "Japplet" but the closest you have is
"JApplet". Even if the Windoze machine you're using has a case-
insensitive filesystem, the jar file's inner filesystem and Java are
both case-sensitive and will see the difference. (Also, if the class
is internally named with a capital A it would still not have worked in
all likelihood. If it is internally named with a small a, then it
won't work even if you change the class to load to use a capital A to
match the jar file name. All three must match case, and with case
insensitive filesystems, the class name on the command line or in the
HTML code and the class name in the source file must still match case.)

Sorry
~
actually the classes I was using were called WP04_Japplet00, etc,
naming/cases were consistent
~
the thing is that I trimmed down the example in order to debug it
using "test00" as the name of file
~
I am still having the problem, which I can notunderstand. Let me
reproduce it cleanly and repost it here

General rule. Tell the truth. When you tell fibs to simplify, you
often mask the source of the trouble. To simplify, simplify your
actual compilable source code, and quote the whole thing precisely.
This process often helps you solve your own problem. See
http://mindprod.com/jgloss/sscce.html

When you have more than one class, organise your classes into
packages. See http://mindprod.com/jgloss/package.html

"." not " _" separates package name from class.
