I have a requirement to map a Table (ProdComp) with composite key,SPSOriginPK with another Table (ItemShipWindow) also having a different composite ke, SPSOriginPK_ItemShipWindow.

The relationship between the 2 tables is one-to-one mapping.

Say, the table names are ProdComp and ShipWindow. There is a one-to-one mapping from ProdComp to ShipWindow for the shipWindow property.

<one-to-one name="itemShipWindow" class="ShipWindow" constrained="true"/>

How do I map a foreign of ShipWindow to the PK of ProdComp?

However, it is giving an error:
org.hibernate.PropertyAccessException: exception getting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of de.gloegl.road2hibernate.SPSOriginPK_ItemShipWindow.?

Can any of you experts help me in this?

Have a look at 'property-ref' and see if it helps in your case:

Hi Jayesh,

Thanks for your reply.

property-ref didn't help. The reason for this may be :

I have got a class A: with 5 PK (Composite id).
I have got a class B: with 4 PK ( Also, a composite id, having the first 4 PK of A).

Now, I need a one-to-one mapping from A->B.
If it were from B->A, then <property-ref> may have helped.

But here, it's not working.

Any help would be appreciated!

Thanks.

Get the latest CGLIB.jar, I think its latest version availbale is cglib-2.1.3.jar

also, please check whether the data type you are trying to retrive, does it contain null value, if it is of type "can contain NUll", then use a wrapper data type in POJO for that variable

I don't think I can use the jar version that you recommend.
However, for the scenario that I mentioned :

[quote]I have got a class A: with 5 PK (Composite id).
I have got a class B: with 4 PK ( Also, a composite id, having the first 4 PK of A).

Now, I need a one-to-one mapping from A->B.

But here, it's not working.

the version change of the jar may not be the solution.

Please help!

Thanks.

This is what I understood:
A's PK = column1, column2, column3, column4, column5
B's PK = column1, column2, column3, column4.
You want a one-to-one relationship in A with B based on column1, column2, column3, column4.

Try this:

I have 2 table's ProdComp and ShipWindow. There is a one-to-one mapping from ProdComp to ShipWindow for the shipWindow property.

ProdComp has 5 PK's (Composite id), the first 4 of these are the PK's for ShipWindow (Composite id).

My problem is to have a one-to-one relationship from ProdComp to ShipWindow for the shipWindow property.
