Hello everyone,

I found this really good tutorial on Hibernate:

Hibernate Tutorial

One thing, the html is not well formatted on one of the sections: Here is the code for that java class so it's actually readable.

    
package com.visualbuilder.hibernate.client; 
 
import org.hibernate.*; 
import org.hibernate.cfg.Configuration; 
import com.visualbuilder.hibernate.*; 
 
public class TestClient 
{ 
    /*    
     * This method builds a default user to check if the Hiernate configuration is working or not    
     */ 
    public User buildUser() 
    { 
        User user = new User(); 
        user.setFirstName("John"); 
        user.setLastName("Elison"); 
        user.setAge(21); 
        user.setEmail("[e-mail]"); 
        return user; 
    } 
 
    /*    
     * This method gets the default SessionFactory configured in hibernate.cfg.xml and opens a session    
     */ 
    public Session openSession()
    {   
        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 
        Session session =sessionFactory.openSession(); return session; 
    }
 
    public User testSaveUser(UserManager manager)  
    {     
        User user = buildUser(); 
        manager.saveUser(user); 
        System.out.println("User saved with ID = " user.getUserId());
        return user;
    }
 
    public void testUpdateUser(UserManager manager,User user) 
    { 
        user.setFirstName("Andrew"); 
        manager.updateUser(user); 
        System.out.println("User updated with ID = " user.getUserId()); 
    }
 

    public void testDeleteUser(UserManager manager,User user)  
    { 
        manager.deleteUser(user); 
        System.out.println("User deleted with ID = " user.getUserId()); 
    } 
 
    public static void main(String[] args)  
    { 
        TestClient client = new TestClient(); 
        Session session = client.openSession(); 
        UserManager manager = new UserManager(session);
        User user = client.testSaveUser(manager);
        client.testUpdateUser(manager,user);
        client.testDeleteUser(manager,user);
        session.flush(); 
    } 
}

For what it's worth, I myself rather like Hibernate's own reference document.
http://www.hibernate.org/hib_docs/v3/reference/en-US/html/

I agree.

I usually use multiple sources when teaching myself something new. I think the documentation does a good job at some things but the actual classes/Interfaces are nicely demonstrated in this tutorial.

I'm actually getting ready to switch back over to the documentation


Also, here is another class that didn't format well...

    
package com.visualbuilder.hibernate.client; 
 
import org.hibernate.Session; 
import com.visualbuilder.hibernate.User; 
 
/**  
* UserManager  
* @author VisualBuilder  
*/ 
 
public class UserManager 
{ 
    private Session session = null; 
 
    public UserManager(Session session) 
    { 
        if(session == null) 
             throw new RuntimeException("Invalid session object. Cannot instantiate the UserManager"); 
        this.session = session; 
    }
 
    public void saveUser(User user) 
    { 
        session.save(user); 
    } 
 
    public void updateUser(User user) 
    { 
        session.update(user); 
    } 
 
    public void deleteUser(User user) 
    { 
        session.delete(user); 
    } 
 
}
