I am getting null value for particular column, while loading the object.

[Rahul Ba]

I have an entity bean which is made using Hibernate annotation.

@Entity
@org.hibernate.annotations.Entity(dynamicInsert=true,dynamicUpdate=true)
@Table(name="[tbDDE]")
public class DElement implements Serializable{

@Column(name = "[ID]", nullable = false, unique=true, updatable=false, insertable=false)
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;


@Id
	@Column(name = "[DAElementID]", unique = true, nullable = false)
	private String dElementId;
}

so, whenever I save the particular POJO, it's get saved into the table properly. Here id is Autogenerated value and dElementId is Primary key.
now, once I save and then try to load the particular entity from DB, i get value of id as null but do get proper value of dElementId.

Now, my question is why I am getting null value for id colum though it has proper value in table. I am commiting the transaction as well as flushing the transaction too, but did not help. Remember as soon as I save the object, I am trying to retrieve the object, because I need id value.

Your id field is autogenerated but you have @Id annotation on the dElementId field??

This is because, DAElementID is primary key in database..hence...ID is is sequence generated value....
Please let me know opinion.
