jruby error

[vinitha pot]

hi,
I am using

jruby 1.2.0
jdk 1.5.0_14
on windows xp,i am constantly getting this error:

C:\JRuby\helloworld>jruby -S rake db:create
(in C:/JRuby/helloworld)
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install
the mysql gem and try again: gem install mysql.
rake aborted!
no such file to load -- mysql
(See full trace by running task with --trace)

I tried the following blog
http://blogs.sun.com/arungupta/entry/getting_started_with_edge_rails
but the error still continues.

I installed and uninstalled jruby several times but the error still repeats.

Please suggest a solution.
