私はJPAを初めて使いました。javax.persistence.PersistenceException：EntryManagerの永続プロバイダ（Eclipselink_JPA）がありません
私はいくつかのテストを行うためにnetbeansでエンタープライズプロジェクトを作成しました。ウィザードでこの永続ユニットを作成しました。私はそれを適切に動作JNDI接続を追加し、それがすでにテストされています：
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="persistencia" transaction-type="JTA">
<jta-data-source>jdbc/nuevaConexion</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="javax.persistence.schema-generation.database.action" value="create"/>
</properties>
</persistence-unit>
</persistence>
その後、私はこれがどのように動作するかを確認するためにいくつかのテスト変数とサンプルエンティティを作成しました：
@Entity
public class Entity1 implements Serializable {
private static long serialVersionUID = 1L;
private String nombre;
private int numero;
/**
* @return the serialVersionUID
*/
public static long getSerialVersionUID() {
return serialVersionUID;
}
/**
* @param aSerialVersionUID the serialVersionUID to set
*/
public static void setSerialVersionUID(long aSerialVersionUID) {
serialVersionUID = aSerialVersionUID;
}
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
// setters & getters
続いて、作ってみましたサービスCreateEntity1それを試してみると、それを呼び出すことによって、DB上に新しい要素を作成しようとする：
public class CreateEntity1 {
public static void main(String[ ] args) {
EntityManagerFactory emfactory = Persistence.createEntityManagerFactory("Eclipselink_JPA");
EntityManager entitymanager = emfactory.createEntityManager();
entitymanager.getTransaction().begin();
Entity1 ent = new Entity1();
ent.setId(1);
ent.setNombre("Mi entidad");
ent.setNumero(123);
entitymanager.persist(ent);
entitymanager.getTransaction().commit();
entitymanager.close();
emfactory.close();
}
}
...しかし、それは動作しません。次のエラーが表示されます。
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named Eclipselink_JPA at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:85) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:54) at service.CreateEntity1.main(CreateEntity1.java:22) C:\Users\hp\AppData\Local\NetBeans\Cache\8.1\executor-snippets\run.xml:53: Java returned: 1 BUILD FAILED (total time: 0 seconds)
私は間違っていますか？
EDIT：永続性プロバイダの名前を適切なものに変更しましたが、今は重大なエラーが発生しています。
EDIT 2：すべてをHibernate型に変更しました。まだ巨大なエラーが発生しています：

'Persistence.createEntityManagerFactory（ "persistencia"）で試してみてくださいを;'、あなたは正しい永続性ユニット名を指定する必要があります。 –
