Actually I don't remember what warbler installs into the lib directory, but if you have jruby-complete.jar you can execute this:

java -jar lib/jruby-complete.jar -S rake db:migrate


jruby-complete works well for migrates. I have a problem running other tasks that need more memory though. The following works with jruby installed:

jruby -J-Xmx2048m -S rake some:task

However when I run:

java -jar /opt/jruby/jruby-complete-1.4.0.jar -J-Xmx2048m -S rake some:task

I get this following error: jruby: unknown option -J-Xmx2048m

Any idea why?
