Hi,

I'm trying to apply composite-id to inheritance hierarchy. This is my situation:

EMBEDDED-ID:

public class NewId implements Serializable {

protected Long id1;
protected Long id2;

public NewId() {
}

@Column(nullable = false, unique = false)
public Long getId1() {
return this.id1;
}

public void setId(Long id1) {
this.id1 = id1;
}

@Column(nullable = false, unique = false)
public Long getId2() {
return this.sourceId2;
}

public void getSourceId(Long id2) {
this.id2 = id2;
}

.....
}

SUPERCLASS:

@Proxy(lazy=true)
@Entity
@Inheritance(strategy=InheritanceType.JOINED)
@Indexed(index=Indexable.MAINCLASS_INDEX_DIR)
@NamedQueries(value={@NamedQuery(name="mainclass.byIds", query="select m from MainClass m where m.id in (:ids)")})
public class MainClass implements Serializable, Authorable, Indexable {

protected NewId newId;

@EmbeddedId
@AttributeOverrides({
@AttributeOverride(name = "id1", column = @Column(name="ID1") ),
@AttributeOverride(name = "id2", column = @Column(name="ID2") )
})
@Index(name="mainclass_idx")
public NewId getNewId() {
return this.newId;
}

public void setNewId(NewId newId) {
this.newId = newId;
}
....
}


SUBCLASS:

@Proxy(lazy=true)
@Entity
@Indexed(index=Indexable.MAINCLASS_INDEX_DIR)
@NamedQueries(value={@NamedQuery(name="subClass.byIds", query="select s from SubClass s where s.id in (:ids)")})
public class SubClass extends MainClass implements Serializable {
....
}

I get compiling:

nested exception is org.hibernate.MappingException: Unable to find column with logical name: id in org.hibernate.mapping.Table(SubClass) and its related supertables and secondary tables


Have you any idea?

Thanks,
rand

the error indicated that it can't find the 'id' as u wriiten in 'm.id'. Have u assigned object 'id'??

No. How can I do it? How can I reference directly for composite-id?

Thanks,
rand
