I have two annotated classes:


@Entity
@IdClass( SkulPopulationRelationshipEndNodePk.class )
@Table( name = "skul_pop_rel_end" )
public class SkulPopulationRelationshipEndNode extends SkulPopulationRelationshipEndNodeBase
{
@Id
private Integer skulNumber;

@Id
private Integer edgeSkulNumber;

@Column( name="edge_type", precision=1 )
private Byte edgeType;

@OneToOne
@LazyToOne( LazyToOneOption.NO_PROXY )
@JoinColumn( name="edge_skul_no",
referencedColumnName="skul_no",
insertable=false,
updatable=false )
@NotFound( action=NotFoundAction.IGNORE )
private OptimizedResultsMeo edgeOptimizedResultsMeo;
}

public class OptimizedResultsMeo implements Serializable
{
@Id
@Column( name="skul_no", length=7 )
private Integer skulNumber;

@Column( name="item_no", length=65 )
protected String itemNumber;
}

Here is the PK class for SkulPopulationRelationshipEndNode:
@Embeddable
public class SkulPopulationRelationshipEndNodePk extends SkulPopulationRelationshipEndNodeBase
{
@Column( name="skul_no", precision=8, scale=0 )
private Integer skulNumber;

@Column( name="edge_skul_no", precision=8, scale=0 )
private Integer edgeSkulNumber;
}

I want to create OneToOne link:
SkulPopulationRelationshipEndNodeBase.edgeSkulNUmber -> OptimizedResultsMeo.skulNumber

I get the following exception when i try to load these 2 classes:

Can anyone point out what changes I have to make to fix this relationship?

The OneToOne mapping you have is actually ManyToOne. Simply change @OneToOne to @ManyToOne and it will work.
