Hi Mike,
I've checked on my program (not that I didn't believe you ;-), and yes: no need to set the Driver.
As Cheong Hee said that'll simplify the config and limit the errors.
Thanks again to all of you. That was instructive.
Andreas

A proper plugin should not require you to set either plugin or driver ... The plugin can be guessed from the subprotocol of your connection url and the plugin can return the default driver name. I believe this behaves properly in all the common plugins at this point.
