Bonjour à tous

je débute sur les EJB 3 et JPA et je commence par un exemple basique qui me pose problème.

Voici ma configuration :
serveur d'application Jboss 5
JDK 1.6
SGBD : mysql
ORM : hibernate

J'essaie de faire un insert dans une table commercial dont voici la DDL :

CREATE TABLE `commercial` (            
                   `COMM_ID` int(11) NOT NULL,               
                   `COMM_TRIGRAMME` varchar(3) NOT NULL,     
                   `COMM_NOM` varchar(255) default NULL,     
                   `COMM_PRENOM` varchar(255) default NULL,  
                   PRIMARY KEY  (`COMM_ID`)                  
                 ) ENGINE=InnoDB DEFAULT CHARSET=latin1
Voici le code de l'entity

@Entity
@Table(name="COMMERCIAL")
public class Commercial {
 
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "COMM_ID",updatable=false)
 
    private int id;
 
 
    @Column(name="COMM_PRENOM")
    private String firstname;
    @Column(name="COMM_NOM")
    private String lastname;
    @Column(name="COMM_TRIGRAMME")
    private String trigramme;
 
//getter et setter
 
}
J'ai une JSP toute simple qui fait appel à une servlet qui fait appel à l'EJB session et en particulier à une méthode qui insert les informations du formulaire de la JSP (nom,prenom et trigramme) dans la base de données.

Mon problème est que à la validation du formulaire, l'insertion me renvoie l'erreur suivante :

La requete hibernate envoyée est :

Hibernate: insert into COMMERCIAL (COMM_PRENOM, COMM_NOM, COMM_TRIGRAMME) values (?, ?, ?)
Je vois bien que il manque l'id COMM_ID dans la requete qui est executer mais je voudrais que hibernate se charge de l'inserer automatiquement.

Je suppose que il y doit y avoir un lien avec les annotations de l'entity mais ...

merci d'avance
