Topic: jruby script / generate jdbc in NetBeans?!?!

Hello!, does anybody know how can i execute the generate jdbc in NetBeans..
I found out some clues in the net that  I need to do this so that i can  use the db:* tasks with JRuby. Help me Please...

i need to prepare the test database with the rake utility in NetBeans when I run the rake db:test:prepare it gives me this error:
