hi
I am using Hibernate 3.0 and had the following question

Does hibernate support the following?

1) one-to-one foreign key association if the foreign key is also a primary key or is part of a composite primary key.

For instance I have a table Transaction where primary key is

TransactionId

and I have a table Payment which has a composite primary key composed of

TransactionId and PaymentId.

If I want a one-to-one relationship between Transaction and Payment can I define TransactionId as a foreign-key in a <one-to-one> hibernate mapping?

2) one-to-one primary key association from a table with a single unqiue primary key to a table with a composite primary key and vice versa.
Taking the same example above can I define TransactionId as property-ref in a <one-to-one> hibernate mapping.

Thanks much
Jaya
