Problème Eclipselink dans un projet javase

Question

Je reçois cette erreur lorsque j'exécute mon projet eclipselink.

Des idées? Pourquoi eclipselink aurait-il besoin de quelque chose de jboss? De quoi jboss jar ai-je besoin? Je voudrais utiliser open jpa, mais pour une raison quelconque, après avoir arrêté quelques persists de mon application, il commence à donner un tas d'erreurs stackoverflow.

Answer 1

Si votre projet est supposé ne pas utiliser JBoss du tout, mais a encore besoin de classe JBoss, que des moyens pourraient:

• soit votre serveur par défaut est JBoss (dans la vue du serveur)
• ou votre persistence.xml dans votre yourProjectEJB/ejbModule/META-INF ne fait référence à JBoss
