javax.persistence.PersistenceException: No Persistence provider for EntityManager named Eclipselink_JPA - jpa

Question

I'm new to JPA and I'm pretty lost in this.
I created an enterprise project in netbeans to do some tests. Created this persistence unit with the wizard. I added it a JNDI connection that works proper and it's already tested:
<?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>
Later, I created a sample entity with some test variables to see how this works:
#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
Then, tried to make the service CreateEntity1 to give it a try, and try to create a new element on the DB by calling it:
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( );
}
}
... but it doesn't work. I get the following error:
Exception in thread "main" javax.persistence.PersistenceException: No
Persistence provider for EntityManager named Eclipselink_JPA at

C:\Users\hp\AppData\Local\NetBeans\Cache\8.1\executor-snippets\run.xml:53:

What am I doing wrong?
EDIT: I changed the name of the persistence provider to the good one, but now I'm getting a serious bunch of errors.
EDIT 2: Changed everything to Hibernate type. Still getting a huge error:

Answer 1

Look at my anwser at my anwser at Simplest working example of Spring Data JPA. To me it was simple enough. Hope it will be as simple to You.

Answer 2

You have missed <provider>... try to add it like this:
<?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">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
...
