Thanks Mike, that brought me one step further:
- javac now runs through, I was using target=1.2 and had to add
source=1.2, too otherwise I got a warning that the option was added
for me.
- Seems the whole stuff has never been built on Linux, all the path
names used backslashes for filenames -- that seems to be ok for java,
but not for the classfile converter. I've converted all to forward
slashes.
- But now I'm getting an error from the old 2.1.2 classfile converter:
convert:

Isn't it strange that javac -- with a -target option -- produces output
that can't be read by old versions of the java software?? Seems I'll
have to try to find a newer version and see if it can produce
backward-compatible output.
Failing that I'll probably try to get this working with a precompiled
applet...

Thanks. I was using the same instructions. But when the old javac
segfaulted I tried on Debian etch which also failed. Then before moving
to windows I asked :-)
