@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Person{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String person_id;
}
public class Telephone{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String telephone_id;
@Persistent
private String person_id; //this field point to Person
}
