Hi,

I have two db tables:
A
long aID; (pk)
string addInfo1;

B (this doesn't have a column for hibernate id, only foreign primary key)
long baID; (pfk) (oneToOne to A object)
string addInfo2;

In the class model are two classes - A and B.
B inherits A, B : A


A
long aID
string addInfo1;

B : A
string addInfo2

How could I map it so that it would work?

Use <joined-subclass>. This is the typical case for you.
