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

Take a look at rawr. It’s intended to make it snake-simple to package  
up JRuby apps as .exe, .app, or as an executable jar.

[http://rubyforge.org/projects/rawr/](http://rubyforge.org/projects/rawr/)

for the gem.

Actual source code is hosted on gitorious:

Thanks. I’ll take a look.
