You can use MySQL with JBoss, of course. JBoss supports plenty of
databases. Moreover key generation schemes can be used.
To be able to suggest good Open Source J2EE frameworks it is necessary
to know more about your requirements. Nevertheless, JBoss is an
excellent start for the combination of Open Source and J2EE (if you need
enterprise features for your application).
