con.pool config looks fine. I hope you have restarted app.server after changing the con.pool settings/ copying the driver files.
What exception do you get now ? (exceptions will be logged in domains/domain1/logs/server.log
You can also try "ping" utility, to check whether the con. settings are correct.
admin console (
http://appserver-host-name:4848), resources > jdbc > connection pool > Your con pool > PING. If ping fails, you will see exceptions in server.log
