Error: Entity <name> has no Id or EmbeddedId

[Martin Frisone]

Hi, guys

I'm mapping a table Persons to a java class Persons:

@Entity
@Table(name = "PERSONS")
public class Persons implements Serializable {
     private static final long serialVersionUID = 1L;
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "ID")
    private Integer id;
    
    @Basic(optional = false)
    @Column(name = "FIRST_NAME")    
    private String firstName;

    @Column(name = "MIDDLE_NAME")
    private String middleName;

    @Basic(optional = false)
    @Column(name = "LAST_NAME")
    private String lastName;

    @Column(name = "ADDRESS")
    private String address;  

and I'm getting the error: "Entity Persons has no Id or EmbeddedId". I don't understand why this happenes since I have the @Id annotation.

I appreciate any help on this. Thanks in advance!

hi!

I don't know, but maybe:
- id != Id
- int and not Integer
