は、私は、WebLogic起動クラスに次のコードからJPAからのEntityManagerFactoryを取得しています問題に直面していますを取得中問題Weblogicの中にHibernateのEntityManagerFactory（EJB3アプリケーション）
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("testEJBPU");
logger.info("Created EntityManagerFactory");
Context ctx = new InitialContext();
ctx.rebind("testEJBPU", emf);
上記のコードは、Hibernateの代わりにOPenJPA EntityManagerFactoryを返すだけです 私のPresistence.xmlファイルには次のものがあります
<?xml version="1.0" encoding="UTF-8"?>

誰かが以前に遭遇した場合、私の解決策を教えてください！ よろしく、 Kazim Raza。
Exceptionの起点を見ると、Hibernateの代わりにOPenJPAから来ています。私は、persistence.xmlファイルのProviderに "org.hibernate.ejb.HibernatePersistence"を設定しているので、それは尋ねる必要がありますFactory StrangeのOpenJPAではなくHibernate！ –
weblogicのEJBコンテナがクラスパス上にpersistence.xmlファイルを見つけることができないことを確かめてください。その理由は、というタグを拾っていないからです！ persistence.xmlへのパスはどこに言及する必要がありますか？ –
