Subject: Q: Packaging JRuby

What are  the options for packaging a JRuby script? I tried the
tutorial from netbeans for making a JRuby Swing application, but it
fails to run; it gets the following error: -e:1:in `require': no such
file to load -- /scripts/main (LoadError). I realize that the tutorial
actually has a bug in it; it refers to the 'swingjruby2.scripts'
package in the text, but 'scripts' in the dialog boxes.

I would like to package JRuby scripts that I am writing to run as
utilities on remote machines that I manage. The machines have the JVM
on them, but JRuby is not installed. I would also like to be able to
send the utilities to customers. They too have the JVM, but no JRuby,
and I cannot expect them to install it (they are computer naive).

The packaging must allow the script to be in a single file (.jar
or .exe).

I have used RubyScript2Exe, but I am planning on also using Java
runtime code in my scripts (like Swing), so the packaging must apply
to JRuby.

Any ideas?

Thanks, Ralph
