jdbc-mysql
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 information see http://dev.mysql.com/usingmysql/java/
Usage
To make the driver accessible to JDBC and ActiveRecord code running in JRuby :
require 'jdbc/mysql'
Jdbc::MySQL.load_driver
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)
