OneToOne problem
Hi, folks
Currently and for this case I have the following configuration, to be run under : JBoss.4.0.3 Sp1 and the EJB3 release coming with this version of JBoss:
This is the root class
@Entity
@Table( name="cdmn_facturas", schema= "CellDom" )
@Inheritance(strategy=InheritanceType.JOINED, discriminatorValue = "OFactura", discriminatorType=DiscriminatorType.STRING)
@DiscriminatorColumn(name="ObjClass")
public class OFactura implements Serializable
{
protected String FactId;
@Id(generate=GeneratorType.NONE)
@Column( name="FactId", nullable=false )
public String getFactId()
{
return FactId;
}
....
}
This is the sublcass involved in the problem
@Entity
@Table( name="cdmn_FacturasCompra", schema= "CellDom" )
@Inheritance(discriminatorValue = "OFacturaCompra")
@PrimaryKeyJoinColumn(name = "FactId", referencedColumnName="FactId" )
public class OFacturaCompra extends OFactura implements Serializable
{
protected ORemision Remision;
....
@OneToOne( targetEntity=ORemision.class,
fetch=EAGER,
cascade=CascadeType.ALL)
@JoinColumn( name="RemId", referencedColumnName="RemId" )
public ORemision getRemision()
{
return Remision;
}
public void setRemision( ORemision remision )
{
this.Remision = remision;
}
....
}
and this is the associated class involved in the problem:
@Entity
@Table(name="cdmn_Remisiones", schema= "CellDom")
public class ORemision extends CEJB3Validator implements Serializable
{
private String RemId;
private OFacturaCompra fact;
....
@Id(generate=GeneratorType.NONE)
@Column( name="RemId", nullable=false )
public String getRemId()
{
return RemId;
}
...
@OneToOne(targetEntity=OFacturaCompra.class, mappedBy="Remision", fetch=EAGER )
public OFacturaCompra getFact()
{
return fact;
}
public void setFact(OFacturaCompra factNo)
{
this.fact = factNo;
}
}
well this configuration at deploy stage posts the following exception:

note that the mappedBy annotation is remarked, this is because when I
ommit this annotation, and configure it as follows :
@OneToOne(targetEntity=OFacturaCompra.class, fetch=EAGER )
@JoinColumn(name="FactId", referencedColumnName="FactId" )
public OFacturaCompra getFact()
{
return fact;
}
it deploys with no exceptions.
I would like to know whether this behaviour is normal as far as the original configuration follows what the Hibernate Annotations and EJB3 Persistence Guides say about OneToOne; or there is something I am not doing well.
Thanks in advance
