With autoincrement=true you generally need to setup a database-specific sequence to handle assigning the value. Or alternatively one of the internal tables provides this functionality. (bringing the thread full-circle :-) )

Thanks Brenden,!!! one short question - then i am quiet! :-) why must i set the PK in my code? customer.setId(123); i described it in XML primarykey="true" autoincrement="true" but got Errsos, when i dont set up the PK. thanks again for a quick ;-) advice ralf --- "Larry V.
