Bonjour,
je réalise actuellement une application en java dans laquelle je souhaite visualiser des états déjà enregistré, et réaliser des exports. Ces rapports en question contiennent des requêtes SQL pour une base Access.

L'application est fait pour du client lourd.

Pourriez vous me donner des exemples pour réaliser le rafraichissement des données des .rpt.

Merci.

PS: j'ai trouvé trois classe généré automatiquement, elles fonctionnes pour afficher les rapports avec des données enregistrés:
