MySQL Connector/J is the official JDBC driver for MySQL.

It is a native Java driver that converts JDBC (Java Database Connectivity) calls into the network protocol used by the MySQL database.

For more see http://dev.mysql.com/doc/connector-j/en/connector-j-overview.html


To make the driver accessible to JDBC and ActiveRecord code running in JRuby :

require 'jdbc/mysql'

For backwards compatibility with older (<= 5.1.13) versions of the gem use :

require 'jdbc/mysql'
Jdbc::MySQL.load_driver(:require) if Jdbc::MySQL.respond_to?(:load_driver)
