E eu tenho uma classe executável também que qdo tento rodar ela,
dá o seguinte erro: Selection does not contain a main type

[code]
public class EventManager {
public static void main(String[] args) {
EventManager mgr = new EventManager();
mgr.createAndStoreEvent(“My Event”, new Date());
HibernateUtil.getSessionFactory().close();
mgr.listEvents();

	Session s = HibernateUtil.getSessionFactory().openSession();
	s.beginTransaction();
			
	Event e = new Event();
	e.setTitle("Evento 1");
	e.setDate(new Date());
	s.save(e);//salvou evento
	
	Person p = new Person();
	p.setFirstname("Cristiano");
	p.setLastname("Pena");
	p.setAge(25);
	
	Set set = new HashSet();
	set.add(e);
	
	s.save(p);
	s.update(p);
	s.getTransaction().commit();
	
	
	//mgr.addPersonToEvent(personId, eventId);
}

private void createAndStoreEvent(String title, Date theDate) {
	Session session = HibernateUtil.getSessionFactory().getCurrentSession();
	session.beginTransaction();
	Event theEvent = new Event();
	theEvent.setTitle(title);
	theEvent.setDate(theDate);
	session.save(theEvent);
	session.getTransaction().commit();
}

private List listEvents() {
	Session session = HibernateUtil.getSessionFactory().getCurrentSession();
	session.beginTransaction();
	List result = session.createQuery("from Event").list();
	session.getTransaction().commit();
	return result;
}

private void addPersonToEvent(Long personId, Long eventId) {
	Session session = HibernateUtil.getSessionFactory().getCurrentSession();
	session.beginTransaction();
	Person aPerson = (Person) session
			.createQuery(
					"select p from Person p left join fetch p.events where p.id = :pid")
			.setParameter("pid", personId).uniqueResult(); // Eager fetch
													// detached
	Event anEvent = (Event) session.load(Event.class, eventId);
	session.getTransaction().commit();
	// End of first unit of work
	aPerson.getEvents().add(anEvent); // aPerson (and its collection) is
										// detached
	// Begin second unit of work
	Session session2 = HibernateUtil.getSessionFactory()
			.getCurrentSession();
	session2.beginTransaction();
	session2.update(aPerson); // Reattachment of aPerson
	session2.getTransaction().commit();
