[b]Hibernate version3

Hey,

I saw a lot of topics on the " Parent child" problem.

But , still dont understand.


suppose Parent can have a lot of childs (one to many)

Is it ok to do:

Child c = new Child();

Parent p = new Parent();

p.getChilds().add(c);

session.save(p)

it dosnt work for me

the parent is cascade - all and inverse - true

what else do i need to do?

Parent
<set name="chi" cascade="all" inverse="true" >
<key column="QID" />
<one-to-many class="hibernate.model.Child" />


Child:
<many-to-one name="par" column="qid" class="hibernate.model.Parent"
