Hello guys,

I have a ruby script that runs perfect from the command line using  
jruby.  
So I tried to compile it with jrubyc and the .class is now generated.

Then I proceed to run it with java -cp .:/pathto/jruby.jar classname and  
I  
receive the following error:

Exception in thread “main” search.rb:2:in `require’: no such file to  
load  
– rubygems (LoadError)  
from search.rb:2  
…internal jruby stack elided…

What am I missing?

Thanks,

Guillermo A.

Maybe you should post this to the JRuby ML rather than ruby-talk.

There’s no one thing that’s true. It’s all true.

Basically you just need to specify where JRuby is located with the  
jruby.home property. Othewise it can’t find things like rubygems or Ruby  
stdlib.

java -Djruby.home=/path/to/jruby -cp .:/pathto/jruby.jar classname
