Problème de connection à la BD Mysql via Java

Quelle est la structure de ta table ?

Champ###Type ##### Interclassement ### Null
---------------------------------------------------
Id #### int(20) ################ # Non
Nom ## varchar(20) # latin1_swedish_ci # Non
Prenom varchar(20) # latin1_swedish_ci # Non
Age ### int(3) ################### Non


ALTER TABLE `table` ADD `Id` INT( 200 ) NOT NULL FIRST ;
ALTER TABLE `table` ADD PRIMARY KEY ( `Id` )
ALTER TABLE `table` ADD `Nom` VARCHAR( 20 ) NOT NULL ;
ALTER TABLE `table` ADD `Prenom` VARCHAR( 20 ) NOT NULL ;
ALTER TABLE `table` ADD `Age` INT( 3 ) NOT NULL ;

Il manque l'Id lors de la persistence de ton objet.

la classe est généré par hibernate synchrinizer, l'Id est bien renseigner :

package hibernate.base;

import java.io.Serializable;


/**

* This is an object that contains data related to the table table.
* Do not modify this class because it will be overwritten if the configuration file
* related to this class is modified.
*
* @hibernate.class
* table="table"

Pas dans la classe table; mais lors de son appel.

PS : n'oublie pas la balise code.

Merci beaucoup pour ton aide ça marche :)
