For ease of maintenance, we used to create another Java class to handle data accessing jobs.
- Create EventDAO.java
package events;
import java.util.Date;
import java.util.List;
import org.hibernate.Session;
import org.zkoss.zkplus.hibernate.HibernateUtil;
public class EventDAO {
Session currentSession() {
return HibernateUtil.currentSession();
}
public void saveOrUpdate(Event anEvent, String title, Date date) {
Session sess = currentSession();
anEvent.setTitle(title);
anEvent.setDate(date);
sess.saveOrUpdate(anEvent);
}
public void delete(Event anEvent) {
Session sess = currentSession();
sess.delete(anEvent);
}
public Event findById(Long id) {
Session sess = currentSession();
return (Event) sess.load(Event.class, id);
}
public List findAll() {
Session sess = currentSession();
return sess.createQuery("from Event").list();
}
}
- You have to compile the Java source, and place the class file in a directory called classes in the Web development folder, and in its correct package. (ex.$myApp/WEB-INF/classes/event/EventDAO.class)
