I would first try and use the latest MySQL jdbc driver ..... 2.0.4 is
pretty old. I use 3.0.11
What version of MySQL are you using?

Hi all,
I have transform an Oracle EOmodel to MySql using switch adaptor.
Everything
works fine, the attribute are translated in the MySql types and I am
able to
fetch anything in EOmodel.
But it seems that I have problems with sub-classes in applications.
I am able to create an object from a sub classe of Substance (defined
by
category = 'CYT') but impossible to read it afterward !
The mysql jdbc driver is mm.mysql-2.0.4-bin.jar
The trace is the following :
