Hi,

I'm struggling with an Hibernate annotations issue several day without any findings, please help me with the following:

I need to have 2 different @Entity classes with the same columns mapping but with a different Identifier. (@id field)

The first one should use id field as identifier.
The second should use name field as identifier.

I have an abstract class, annotated with @MappedSuperclass that have all of the columns including id and name, and in addition 2 @Entity sub classes that overriding the getters of the id and name.

@MappedSuperclass
public class MappingBase {
protected Integer id;
protected String name;

@Column (name = "ID")
public void getId() {
return this.id;
}

@Column (name = "NAME")
public void getName() {
return this.name;
}
}

@Entity
@Table (name = "TABLE")
public class Entity1 extends MappingBase {

@Id
@Column (name = "ID")
public void getId() {
return this.id;
}
}

@Entity
@Table (name = "TABLE")
public class Entity2 extends MappingBase {

@Id
@Column (name = "NAME")
public void getName() {
return this.name;
}
}

Note: I must have the members (id,name) in the super class.

I know that i can add @Transient to the id and name getters but this means that i must add both of them (id and name fields) in each class and it's not a good design :(
In addition, in the exception that I'm getting it says to add the following insertable="false, updateable=false. it helps but i don't understand what is the meaning of this... and i don't think that it's the solution.

Please help me to understand if it's possible to implement.

Thanks!
