Salut
J'ai crée une classe connexiondb, une classe filiale et un formulaire JFfiliale
et aprés avoir entrer des infos dans le JFfiliale à execution il me retourne l'erreur suivante:erreur lors connection db(java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL server]'filiale' :nom d'objet incorrect.)

voici le code de la classe filiale
