packaging jruby gems in self contained jar

I'm trying to package compass/sass into a self-contained jar so that I can use compass without installing jruby.

I installed jruby and warbler on a Windows7 machine, running Java 1.6.0_37

I created a folder, named it jrcompass, then installed compass into it, i.e. 

jruby -S gem install compass -i .

then I ran in it:

jruby -S warble

which created a file named jrcompass.jar of about ~20MB in size. so far so good.

problem is that when I try to execute the jar I get an error message (below). it seemed from the error that jruby.home was not set, so I passed it as a property in the command line and that worked, but it defeats the purpose of having a self-contained jar.

if I try to pass . as jruby.home then I get an error that it can't find rubygems

any help would be appreciated. TIA.

C:\Apps\test\jrcompass>java -jar jrcompass.jar
