Subject: creating a simple executable jar containing ruby code

Hi,

 I'm a relative noobie ruby dev and I was poking around with rawr. I
wrote a simple .rb file and then used rawr to package it into a jar but
have run into some errors.
 I have brought it down to bare bones to understand how this all works
so I have one ruby file called rubytest.rb.

I ran
> rake rawr:jar

 which produces a package/jar/Test.jar for me. All very well and good
until I try to execute the jar with

>java -jar package/jar/Test.jar.

 This gives me and error of:

 $ java -jar package/jar/Tests.jar
Exception in thread "main" org.jruby.exceptions.RaiseException:
(LoadError) no such file to load -- main
        at org.jruby.RubyKernel.require(org/jruby/RubyKernel.java:1038)
        at #<Class:0x100ac06d4>.(root)(<script>:1)

I'm not sure what is wrong, am I missing something here?

thanks
