I use Oracle 9i and I have this problem.

TABLE PEOPLE
COLUMNS:

CD_PEOPLE (PK) - value genereted by sequence oracle
DT_NASC (PK)
NM_PEOPLE

How can I use composite-id and mapping genereted called sequence.

Thank you for your help, but I talk about SEQUENCE ON ORACLE, there are little diference between auto-increment and sequence.
We talk about Oracle remember.

Zippy.

Maybe you need to subclass SequenceGenerator or implement your own IdentifierGenerator.

Can't help you there. Don't know Oracle from Adam. Good luck.

CD_PEOPLE (PK) - value genereted by sequence oracle
DT_NASC (PK)

it's not because your oracle primary key is composite that your pojo must define exactly the same composite id.
You surely have a good reason why your composite primary key is defined like this but for me it has no sense in the "object world", the only field CD_PEOPLE allows you to define correctly the object unicity as it is a sequence.

So just define CD_people as the id of your pojo and let dt_nasc as a not null property.
