Hi. I am playing with ruby processing, which I installed by gem. I managed to run WishyWorm demo from samples:
rp5 unpack samples
rp5 run samples/contributed/jwishy.rb
It works well. But next step I try to run it as an applet
rp5 applet samples/contributed/jwishy.rb
opera jwishy/index.html
Then I've got:

Trace level set to 5: all ... completed.network: Cache entry not found [url: file:/home/x/Dokumenty/projekty/automaty%20komorkowe/01/rp2/jwishy/core/core.jar, version: null]

I tried to run it from site where it is deployed http://s3.amazonaws.com/jashkenas/ruby_processing_gallery/jwishy/index.html and this time error is java.lang.ClassNotFoundException: org.jruby.JRubyApplet

So I came back to my local sample and try to change jruby-complete.jar to another one. I downloaded the newest one from svn trunk and build it by
ant jar-jruby-complete
After changing jars many errors appered, but when I signed this jar by my fake-certificate it is close to make it work:

What's wrong this time?
I would be the most happy fixing first issue LOGDIR. It will allows me to using stable release without my fake-certificates.
Is it possible to turn off logging? I wonder if even LOGDIR is set, will applet try to log messages on hard drive? Isn't it restricted area by non-signed applets?
Thanks for any help.
