EmbeddedId and GeneratedValue

[jc7442]

I'd like to use an embeddedID for some of my classes. Th class PK is an embeddable, it contains one field:

private long id;

I'd like to generate the value, I've try:

@Id
 @GeneratedValue(strategy = GenerationType.TABLE)
 @Column(name="CUST_ID")
 private long id;

In that case annotaions are not used (PK is not generated).

Any idea how to have a generatedValue for a PK in a embeddedID ?

PS: I'd like to use an embedded ID for typing the PK. I do not like to see long everywhere in the application. It may be bug prone.

Ive try the same kinds of think with IdClass:

@Entity
@Table(name = "WAREHOUSE")
@IdClass(WarehousePK.class)
public class Warehouse {
 long name;

 String city;

 @Id
 @GeneratedValue(strategy = GenerationType.TABLE)
 @Column(name = "W_NAME")
 public long getName() {
 return name;
 }
...
}

GeneratedValue annotation is ignored.

Any idea on how to have a typed PK with a generated value ?
