Sounds like you may have a different classloader
best to use the class loader that the DriverManangerConnectionFactory uses
e.g.
Class.forName("com.mysql.jdbc.Driver", true,
DriverManagerConnectionFactory.class.getClassLoader());Let me know how you make out,

Unfortunately I'm not at home, which is where my MySQL implementation is, so I can't show you what I'm doing for another 7-8 hours :(
On the other hand the MySQL folk have some great documentation and help forums that could probably help you more, if no one else has any solutions for you here.
