hibernate gen table error org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build()" because "entityManagerFactoryBuilder" is null

I fail to generate table from entity in eclipse with error org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build()" because "entityManagerFactoryBuilder" is null
I have three hibernate classes :
#Entity

abstract public class GameBean implements Serializable {

When I try to generate the tables with the JPA Tool/Generate Tables from Entries, the above error appears and no generation is done.
I would be really cool to get help with that, its a little time I'm on it !

I succeed in making it work. I used in Console Configuration a Annotation (Jdk 1.5+) type and a Hibernate Version 4.3. And then I succeeded in generating the tables with this console configuration. As I didn't understand what was wrong, I can't explain the solution. It works as well with JPA, with persistence.xml as follows
<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" xmlns="http://java.sun.com/xml/ns/persistence">

Java EE/ JPA #PersistenceContext(unitName = ) doesn't inject Hibernate entity manager implementation

Currently, I learn the Java EE JPA specification. I am using Hibernate as JPA implementation. And I have the next issue:
I have a simple entity
#Entity
public class Book {
#Id
#GeneratedValue
private Long id;
private String title;
private String description;
private Float unitCost;
public Book() {
}
// getters and setters
}
And a simple Service:
public class BookService {
#PersistenceUnit(unitName = "book_store")
private EntityManager entityManager;
public void create(Book book) {
entityManager.persist(book);
entityManager.flush();
}
}
The persistence.xml has next view:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence 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_2.xsd"
version="2.2">
<persistence-unit name="book_store">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>com.example.jpatest1.Book</class>
<properties>
<property name="javax.persistence.jdbc.driver"
value="com.mysql.jdbc.Driver"/>
<property name="javax.persistence.jdbc.password"
value="somePasss"/>
<property name="javax.persistence.jdbc.user" value="sammy"/>
<property name="javax.persistence.jdbc.url"
value="jdbc:mysql://localhost:3306/book_store?
autoReconnect=true&useSSL=false"/>
<property name="hibernate.dialect"
value="org.hibernate.dialect.MySQL5Dialect"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
And I don't understand why the Hibernate Session don't inject into BookService. In book service as EntityManager I got org.jboss.as.TransactionScopedEntityManager instead of SessionImpl from Hibernate. Why using #PersistenceContext(unitName = ) I don't get Hibernate EntityManager implementation?
Also, I pin link on github: link on code source

The type of the object field entityManager is EntityManager, so you get injected what you declared in that field.
To get session from EntityManager, you can try this:
Session session = entityManager.unwrap(Session.class);

Eclipse - JPA EclipseLink Generating tables from entities

Hi i'm trying to generate db tables from entities in eclipse. but it does not show schema generation dialog as shown in this link. when i click "Generate table from entities" it does nothing.

JPA ManyToMany anotation for not load all items in set

I have User class and BattleReportILogItem class. This class (User, BattleReportILogItem) are #Entity.
User have 0..N BattleReportILogItem.
USER
#Entity
#Table(name = DomainConstant.TABLE_USER)
public class User implements Serializable {
#Id
#Column(name = DomainConstant.DOMAIN_USER_ID)
#GeneratedValue
private Long userId;
#ManyToMany(cascade = {CascadeType.ALL})
#JoinTable(name = DomainConstant.VIEW_USER_BATTLE_LOGS, joinColumns = {
#JoinColumn(name = DomainConstant.DOMAIN_USER_ID)}, inverseJoinColumns = {
#JoinColumn(name = DomainConstant.DOMAIN_BATTLE_REPORT_ID)})
private Set<BattleReportILogItem> setOfBattleLogs = new HashSet<>();
....(other stuff, get and set methods...)
BattleReportILogItem
#Entity
#Table(name = DomainConstant.TABLE_BATTLE_REPORT)
public class BattleReportILogItem implements Serializable {
#Id
#GeneratedValue
#Column(name = DomainConstant.DOMAIN_BATTLE_REPORT_ID)
private Long BattleReportILogItemId;
#ManyToMany(mappedBy = "setOfBattleLogs")
private Set<User> setOfBattleLogs = new HashSet<>();
....(other stuff, get and set methods...)
The problem is, that I load User program loads all data in private Set<BattleReportILogItem> setOfBattleLogs = new HashSet<>();. This mean 1 000 000 000 items in my set setOfBattleLogs. I don't want load data to this set. For load data i have BattleReportLogItemDao DAO.
Is there any solution how to NOT LOAD DATA to my set?
I hope, you understand me... :-))
Thank you for your help.

EDIT 2:
For load user I am using the code:
#Override
public User findByEmail(String email) {
TypedQuery<User> q = em.createQuery("SELECT u FROM " + User.class.getSimpleName() + " u WHERE u.email = :uemail", User.class);
q.setParameter("uemail", email);
try {
return q.getSingleResult();
} catch (NoResultException e) {
return null;
}
}

You can use the parameter fetchtype Lazy. Now your strategy seems to be Eager.

Hibernate Auto Detection in Persistence.xml Not Working

I've read Do I need <class> elements in persistence.xml? and How to auto detect entities in JPA 2.0 and followed their tag useage in my persistence.xml, but Entitys are not being auto detected by Hibernate. When I remove the <class> tag this no longer works and I get a MappingException. For some reason I can't seem to enable auto detection. NOTE this is a stand-alone hibernate application (shouldn't matter as far as I know). I have this example:
Persistence.xml:

You should try using HibernatePersistenceProvider and remove the <class> element from the persistence.xml.
Also remove <exclude-unlisted-classes> since it is not applicable to Java SE persistence units as per the official schema definition http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/persistence/persistence_2_1.xsd
<?xml version="1.0" encoding="UTF-8"?>

I noticed that you are inter mixing JPA code with Hibernate code. If you're using JPA then try to stick to JPA.
Use the following code after creating the EntityManager:
EntityTransaction tran = manager.getTransaction();
tran.begin();
try {
Person savedPerson1 = manager.merge(new Person("Carl", "Gauss"));
Person savedPerson2 = manager.merge(new Person("Benoit", "Mandelbrot"));
tran.commit();
} catch (Exception e) {
tran.rollback();
}
manager.close();
factory.close();
Remember to access the returned entity from EntityManager.merge() call to access any auto-generated fields.
You should use the following Maven POM dependencies for the above to work as expected in a Java SE environment:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.3.8.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.1-api</artifactId>
<version>1.0.0.Final</version>
