Thanks!
now OJB 1.0.rc5 works fine
it makes me now PKs automaticly
thanks
but it doesn�t deal with
foreignkey
customer --> car
i do
cu = new Customer();
cu.setName("foo");
car = new Car();
car.setColor("blue");
cu.setCar(car);
...
broker.store(cu);
okay
in DB is a new car and a new customer.
but carId in table customer is ="0".
(car has a new PK become by db)
in xml i did this in customer-describtion:
<reference-descriptor
name="car"
class-ref="de.ralle.Car"
auto-retrieve="true"
auto-update="true"
auto-delete="true">
<foreignkey field-ref="carId"/>
</reference-descriptor>
in class Customer
i have this:
Car car;
int carId;
any idea?
i watched docu,in internet, saw tutorial3
but it is not deliverd with OJB.
so please not be angry (because of lots questions)
(i last worked with 0.94... sorry)
Thanks advice!
