Rspec error while running jruby -S rake spec

Hello All,

I followed steps to install Rspec as in the link pasted below.

http://www.pmamediagroup.com/2009/04/tutorial-install-rspec-rails-factory-girl/

I have jRuby on Rails installed on my machine.Hence all commands need
to be run with jruby -S extension.
However when I run the jruby -S rake spec command,I get the following
error as shown below.


C:\Rspec Test>jruby -S rake spec --trace

What does the error indicate,I tried commenting all lines having
drop_database statement in them.
Another thing is that the database already has tables and by using the
tutorial I have just added another table for the bank-account.
Kindly let me know what exactly needs to be done in this case

Thanks & Regards
