jportable and mysql-connector

I need to run a Java app that connects to a mysql database.
I was provided with a driver (jar-file) called mysql-connectro-… that will handle the connection.
Can jportable handle this kind of things?
If so, where does the driver have to go?

I re-installed Java for now.
Without the driver I cannot make connection to the database either, but if I place the driver in C:\Program Files\Java\jre7\lib\ext\ the database connection is there and I can view and edit the data.

The app is working fine in jportable as long as I do not use functions that require the database.
