@Entity
public class Name implements Serializable {
   @XmlAttribute(name = "rid")
   public String rid;
   @XmlElement(name = "description")
   public String description;
   @XmlElement(name = "language")
   public String language;

      return rid;
   }

   @ManyToOne
   @JoinColumn(name = "name")
   public Customer getCustomer() {
      return customer;
   }

   public String getDescription() {return description;}
   public String getLanguage() {return language;}

   public void setRid(String rid) {this.rid = rid;}
   public void setDescription(String description) {this.description = description;}
   public void setLanguage(String language) {   this.language = language;}
   public void setCustomer(Customer Customer) {this.customer = Customer;}
}

Cio che ottengo è:

    create table Name (
        rid varchar(36) not null,
        description varchar(255),
        language varchar(255),
        name varchar(36),
        primary key (rid)
    )

    create table customer (
        rid varchar(36) not null,
        simpleName varchar(255),
        primary key (rid)
    )

    alter table Name
        add index FK24EEAB295251 (name),
        add constraint FK24EEAB295251
        foreign key (name)
        references customer (rid)

A questo cerco di aggiungere un Customer al mio db...

   private static void newCustomer(){
      Customer customer = new Customer();
      ArrayList<Name> nameList = new ArrayList<Name>();
      Name name = new Name();
      name.setDescription("Duke");
      name.setLanguage(Language.EN.toString());
         nameList.add(name);
      name.setDescription("Duca");
      name.setLanguage(Language.IT.toString());
         nameList.add(name);
      name.setDescription("Ducas");
      name.setLanguage(Language.DE.toString());
         nameList.add(name);
      
      customer.setSimpleName("duke");
      customer.setName(nameList);
      
      dbEngine.createBean(DbSchemas.MANAGEMENT, customer);
   }

   public void createBean(DbSchemas dbSchemas, Object bean) {
      DbConnector connector = getDbConnector(dbSchemas);
      connector.getConfiguration().addAnnotatedClass(bean.getClass());
      Transaction tx = null;
      Session session = connector.getSessionFactoryUtil().getInstance().getCurrentSession();
      connector.getSessionFactoryUtil().openSession();
      try {
         tx = session.beginTransaction();
         session.save(bean);
         tx.commit();
      } catch (RuntimeException e) {
         if (tx != null && tx.isActive()) {
            try {
               // Second try catch as the rollback could fail as well
               tx.rollback();
            } catch (HibernateException e1) {
               System.out.println("Error rolling back transaction");
            }
            // throw again the first exception
            throw e;
         }
      }
   }


ma ottengo:
