In your previous post you said "mysql db with autoincrement the
database", so does it mean you are using database identity columns (and
SequenceManagerNativeImpl) or do you use sequence id's generated by OJB
(e.g. SequenceManagerHighLowImpl)?
Seems to me that im using, SequenceManagerHighLowImpl, the strange is that i
have exactly the same type of objects with no problems what so ever, the only
differecne is the java class name, identical metamappings, and java execution
code... below my repository_database.xml.

I don't think so.
