Hibernate 2.1 - Oracle 9i

Hi everybody

I have this schema in my data model:

A table named "Comercio" and a table named "Dom".

The "Dom" table have the Comercio_ID column.

In the businnes part, I have this (domain layer) objects:

One Called "Negocio" whit these properties:

public class Negocio extends Comercio
{

/**
* @roseuid 4048BB1702AC
*/
public Negocio()
{

}
}

And "Comercio", that is an abstract class:

public abstract class Comercio extends ComercioLight implements IComercio
{
......

private IDom m_domicilioComercial;
private IDom m_domicilioFiscal;
......
}
And my persistent class DomNac (extends Dom that implements IDom):

public class DomNac extends Dom
{
......
private Long m_sucursal;
......
}

I also give you the Dom abstract class:

public abstract class Domicilio implements IDom
{
private long m_oid;
private String m_calle;
.......
}

and IDom:

package mx.com.prosa.bdu..... blah blah;
public interface IDomicilio
{
}

Then I have my mapping documents, obviously from my Two objects in cuestion: DomNac object to the Dom Table and the Negocio Object to the Comercio table.

If you have noticed, the comercio object, have two dom objects, from the IDom type, I think the problem is in there.

Study the DTD. type is irrevelent for component (should be class in your case)
