これはこれまでこれを修正しようとする私の3番目の質問です。私はすでに多くのことを試しましたが、これは失敗を続け、まったく同じエラーを繰り返し投げます。今回は誰かが私を助けることができるかどうかを見てみましょう。Hibernate/JPAは動作しません
を参照してください、これは私のpersistence.xmlのです：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

<persistence-unit name="PruebaswebPU" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>java:app/jdbc/nuevaConexion</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<!-- Hibernate properties -->

</persistence>
これは、JNDI接続プール "JDBC/nuevaConexion" を介してWAMP MySQLサーバに接続します。ここで
私はそれを使用しよう：私はいつもそれがプロバイダを変更するために私に語ったので、奇妙で、このエラーを取得
public class samplePersistence {
public static void main(String[] args) {
EntityManagerFactory emfactory = Persistence.createEntityManagerFactory("PruebaswebPU");
EntityManager entitymanager = emfactory.createEntityManager();
entitymanager.getTransaction().begin();
testEntity ent = new testEntity();
ent.setId(5l);
ent.setNombre("One name");
entitymanager.persist(ent);
entitymanager.getTransaction().commit();
entitymanager.close();
emfactory.close();
}
}
、しかし...（私のエンティティとして、テスト目的！）それはすでに変更されています。確認：
