java.lang.NoClassDefFoundError: org/hibernate/boot/registry/classloading/spi/ClassLoaderService

Question

I'm a newbie at hibernate and I'm trying to test my entities (persistance) and this error keep showing

Exception in thread "main" java.lang.NoClassDefFoundError: org/hibernate/boot/registry/classloading/spi/ClassLoaderService
at org.hibernate.jpa.HibernatePersistenceProvider.getEntityManagerFactoryBuilderOrNull(HibernatePersistenceProvider.java:80)

... 6 more

This is my entity

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
 public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int idUser;
...
private boolean isAdmin;

(with getters and setters and constructor of course)

and this is the test class

public class PersistTest {
public static void main(String[] args) { 

    EntityManagerFactory emf=Persistence.createEntityManagerFactory("PU");
    EntityManager em = emf.createEntityManager();
    Session s = new AnnotationConfiguration()  
            .configure().buildSessionFactory().openSession();
    Transaction t = s.beginTransaction();

    User c = new User();
    c.setIdUser(1);
    ...
    c.setAdmin(true);

    em.persist(c);
    t.commit();
    s.close();
    System.out.print("success");
}

and this is persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/persistence        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
         version="2.0">
  <persistence-unit name="PU" transaction-type="RESOURCE_LOCAL">
  <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
           <properties>
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/GBO1" />
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="" />
  </properties>

and this is my hibernate dependencies

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.0.6.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-commons-annotations</artifactId>
<version>3.2.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>ejb3-persistence</artifactId>
<version>3.3.2.Beta1</version>
</dependency>

and thanks in advance :)

whats with all of the Hibernate-specific Session/Transaction nonsense? JPA does all of that. NoClassDefFound means you either don't have that class or one of its dependents present. And bearing in mind that "hibernate-annotations" hasn't been released in years, perhaps you don't need that at all. I'm sure the Hibernate docs should tell you — Neil Stockton

You mix a JPA approach (using EntityMananger) and a Hibernate Session approach.
You use Hibernate 3 libraries (3.5.6-Final) and Hibernate 5 hibernate-entitymanager (5.0.6.Final).

You can use to getting started
