I'm trying to run a sample JPA based project. I get the error from the title all the time.
I looked here: No Persistence provider for EntityManager named
but found no working solution there.
Here is my pom.xml:

It's possible that I have some dependencies that I don't need. As I'm inexperienced I must honestly admit, I was quite desperate and looked for any possible answer, and during that process I added some dependencies that may not be used at all.
Here is the class supposed to make the EntityManager
package ~path.examples.service;
import ~path.examples.testjpa.domain.Person;
import javax.persistence.*;
/**
* Created by ME on 2015-04-22.
*/
public class JpaTest {
public static void main(String args[]) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("jpaTest");
EntityManager em = entityManagerFactory.createEntityManager();
EntityTransaction userTransaction = em.getTransaction();
userTransaction.begin();
Person person = new Person();
person.setFirstName("Charles");
person.setSurname("Dickens");
em.persist(person);
userTransaction.commit();
em.close();
entityManagerFactory.close();
}
}
Also:
Im pretty sure that all the files are in the appropriate locations, I also had some problems with me, but I seem to have eliminated that problem (other errors pop out than before) :)
It's probably something obvious that I'm missing, thanks in advance for any help!
edit: It's very likely that the problem lies in persistance.xml file, so here it is (thanks for pointing it out). The location of the file is src/main/resources/META-INF
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"

Maybe you didn't add Hibernate jars to the project classpath? Missing provider jars (in this case Hibernate) will not show you compile errors, as they are required during the runtime.

You need to change:
<provider>org.hibernate.ejb.HibernatePersistence</provider>
to:
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
