Persitence .xml dans WEB-INF/classes/META-INF est

Toute aide appréciée.

répondre à ma propre question ici .......

La seule chose qui a fonctionné pour moi la liste de chaque entité de domaine dans persistence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
      xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" 
      version="2.0"> 
    <persistence-unit name="spring-jpa" > 
     <class>com.multiplan.edi.common.domain.AuditTrail</class> 

    </persistence-unit> 

</persistence>

La raison pour laquelle vous voyez l'exception posté est que nous avaler une exception lancée par le EntityManager en essayant de rechercher un EntityType à partir du Metamodel. J'ai créé a JIRA issue pour garder une trace de cela.

D'une manière générale, la nécessité de répertorier les classes dépend explicitement de la configuration de votre fournisseur de persistance JPA. Certains d'entre eux peuvent être configurés pour analyser un paquet pour les entités. D'autres exigent de lister au moins les classes racine.
