3 @Entity @Table(name = "I48502_EVENTSTORE") public class I48502EventStore extends EventStore {}de mon persistance.xml sélectionne uniquement la classe définie dans l'unité de persistance.

Mais en fait j'obtiens des Warnings qui m’informe qu'aucune classe ne peut être persisté.
j'ai lu et relu la doc, mais quelque chose m'échappe.

J’ai donc essayé à tatons.
Ajouter un @Entity à la classe mère ne change quasiment rienSi une âme charitable pouvait m'éclairer de ses lumières, je lui en saurais gré.

le but est donc de définir un @Entité qui peut être persisté dans deux tables différentes
