Subject: Problems executing example code from xruby

Dear all,

I am experiencing problems while executing the example
script from xruby, which should generate Java *class
code from ruby *rb scripts.
So the error I am getting requires some Java,
and xruby rather than ruby knowledge.

I am going through the example at

http://code.google.com/p/xruby/wiki/XRubyHackingGuide,
 and I get the error below.

From the little Java I know so far, I suspect
that this error is due to java not finding the class
file that xruby generates. Is this true? Where are they
stored -- inside a *jar file ? How do I tell java where they are?

Thank you very much.

Best regards,

Axel
