hi ... again :-(
it is really frustratingly... i turned OTM->true made: customer.setCar(car) broker.store(customer);
I don't know what's wrong with your test, but this will definitely work with the PB-api.
You can find many examples in test suite, e.g. ...broker.AnonymousFieldsTest.
regards, Armin
but same... customer is in DB, car not! :-(
i have read in aritcle in german-javamag on OJB there was said "all is nice"
or am i to stuid?
i though it would be possible to store "customer" and his car... has anyone a "runnig"-case for an idot, like me?
thanks!

*can* actually be done in the OTM if Car is a truly dependent object
(otm-dependent attribute), but in the PB an object must be made
explicitly persistent.
broker.store(ca); broker.store(cu);

Hi Brian, now i got an "anonym" id (very nice, so i now have "pure" javaBeans no technicals in it :-)
i made cu = new Custiomer(); ca = new Car(); cu.setCar(ca); broker.store(cu);
now only a customer was in DB
i must add the "auto-*" in descriptor: <reference-descriptor name="car" class-ref="de.ralle.Car" auto-retrive="true" auto-update="true" auto-delete="true"> <foreignkey field-ref="carId"/> </reference-descriptor>
now i have a car and a customer, but custumer.carId is "null" in database... of course carId is anonym too! ...
any idea? or am i to silly and i must do pure sql ... as a penalty... ? :-)
in table customer is: CREATE TABLE CUSTOMER ( ID INT PRIMARY KEY AUTO_INCREMENT, CARID INT, FOREIGN KEY (CARID) REFERENCES CAR(ID) );
thanks!

Thanks
Brian,
but do you mean with "anonymous" keys ?
now i have (in classes): CUSTOMER car: Car carId: int
CAR: id: int
(and the XML desc for it like in mail before) am i with anon.keys able to "see" car-fk in database-table CUSTOMER? after: broker.store(customer); ?
thanks again, and thanks for your patience. greetings!
On the FK thing, if you do not use anonymous
FK's
the ID's need to be managed manually, as well as the references. I
tend
to recommend using anonymous keys for FK relationships because it
is
very easy to forget this.
