Did someone succeed in running 0.7.7-dev version on non-derby db?

Hello,
we are trying to make the 0.7.7-dev version of openjms running on a 
postgres and on a mysql dbms.
The version of postgres is a 7.2.7 (jdbc driver 7.2) on a linux Red Hat 
machine whilst mysql is version 3.23.58 (jdbc driver mysql-connector 
3.0.15).
In both cases we get fatal exceptions running the dbtool.sh script (our 
other sample programs using the same drivers/db work perfectly).
Has anyone made it to run dbtool.sh on a dbms different than derby? What 
exactly are we missing?
Thanx,
M.
