Heya qmx!
we was in the middle of switching from pure orm.xml to hbm.xml (in order to allow column indexing in JPA 2.0),
when we found out the 'sequence' generator does not really work with MySQL (the MySQL adapter complains about not supporting that configuration).
So Gunnar recommended 'enhanced-sequence' which should basically be a sequence that use fallback strategy and it should be compliant with how Hibernate operates for JPA 2.0 sequence configuration.
I would be perfectly happy with any solution that would allow us to use the same strategy as before, but the problem is we didn't find one.
Do someone has any suggestions?
