Я установил плагин hibernate для NetBeans и не могу подключиться к базе данных MySQL - код:
package client;
import org.hibernate.*;
import org.hibernate.cfg.*;
import java.util.*;
public class HiberTest {
private static SessionFactory sessionFactory;
private int id;
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
protected static void setUp() throws Exception {
// A SessionFactory is set up once for an application
sessionFactory = new Configuration()
.configure() // configures settings from hibernate.cfg.xml
.buildSessionFactory();
}
public static void main(String[] args) throws Exception {
setUp();
Session session = HibernateUtils.getSessionFactory().openSession();
session.beginTransaction();
Query q = session.createQuery("CREATE TABLE test(myInt int not null)");
List resultList = q.list();
System.out.println(resultList);
session.getTransaction().commit();
session.close();
}
}
HibernateUtils.class
package client;
import org.hibernate.cfg.*;
import org.hibernate.SessionFactory;
public class HibernateUtils {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
return new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
Ошибки:

Пожалуйста, помогите мне с этим, что является препятствием для меня, чтобы иметь дело с гибернацией.
После всех изменений cfg я решил опубликовать cfg.xml и hbm.xml, может быть, кто-то предложит что-то здесь:
cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
