Простые H2 и Hibernate/JPA - программирование

Простой тест с H2 в качестве базы данных, JPA и Hibernate. Не дает четкой ошибки, но она не сохраняется. Наверняка, мне не хватает чего-то чрезвычайно простого.

persistence.xml в META-INF/:

<?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_1_0.xsd" version="1.0">

  <persistence-unit name="thePersistenceUnit" transaction-type="RESOURCE_LOCAL">
     <provider>org.hibernate.ejb.HibernatePersistence</provider>

    <class>entities.Person</class>

    <properties>
        <property name="connection.driver_class" value="org.h2.Driver"/>
        <property name="hibernate.connection.url" value="jdbc:h2:./db/repository"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
        <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
        <property name="hibernate.show_sql" value="true" />

    </properties>
</persistence-unit>

простой объект:

@Entity
public class Person {

    @Id
    @GeneratedValue
    private Integer id;
    private String firstName;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }


    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
}

тест:

public class Testing {
    @Test
    public void test2(){

        EntityManagerFactory factory = Persistence.createEntityManagerFactory("thePersistenceUnit");
        EntityManager theManager = factory.createEntityManager();
        assertNotNull(theManager);

        Person person = new Person();
        person.setFirstName("ana");
        theManager.persist(person);
        System.out.println(person.getId());

        Person p = (Person)theManager.find(Person.class, 1);
        System.out.println(person.getId());

        assertNotNull(p);
    }
}

результат:

Вопрос: почему он не сохраняет экземпляр/почему он не вызывает никаких ошибок и т.д.?
