As of jruby1-.40, you can also use jruby’s gem and

gem install jdbc-mysql

then after the following entry

require ‘java’

add

require ‘rubygems’
require ‘jdbc/mysql’

and loose the Class.forName Java method.

I tried this with Oracle instead of MySQL, and this does not work:

JavaLang::Class.forName(“com.mysql.jdbc.Driver”).newInstance

I found a post somewhere where Charles Nutter (mr. JRuby himself) explained that Class.forName() doesn’t work because of some classloader issues. This does work instead of the line above:

import ‘com.mysql.jdbc.Driver’
