Mapping issue in hibernate.cfg.xml

[vivek dhiman]

Hi during the execution of simple Java Program Configuration file not able to load the .hbm file. I have done few example in netbeans but in eclipse this encountered. Below is my code under eclipse java project.

package com;

public class Person
{
	int id;
	String name;
	public Person()
	{ 		
	}
	public Person(int id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

Below is my Main Class

package com;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class PersonDetail
{
	private static SessionFactory sessionFactory;
	private static ServiceRegistry serviceRegistry;

	public static void main(String[] args)
	{
		Session session = null;
		try 
		{
			try
			{
				Configuration cfg = new Configuration().addResource("person.hbm.xml").configure();
				serviceRegistry = new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry();
				sessionFactory = cfg.buildSessionFactory(serviceRegistry);
			}
			catch (Throwable ex)
			{
			   ex.printStackTrace();
			}
			session = sessionFactory.openSession();
			
			Person person = new Person();
			System.out.println("Inserting Record");
			Transaction tx = session.beginTransaction();
			person.setId(2);
			person.setName("Vivek");
			session.save(person);
			tx.commit();
			System.out.println("Done");
			session.close();
		} 
		catch (Exception e) 
		{
			System.out.println(e.getMessage());
		} 
		
	}
}

My mapping file that is in com package :

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated Sep 26, 2012 8:50:53 PM by Hibernate Tools 3.4.0.CR1 -->
<hibernate-mapping package="com">

            <generator class="assigned" />
        </id>
        <property name="name" type="java.lang.String">
            <column name="NAME" />
        </property>
    </class>
</hibernate-mapping>

My hibernate.cfg.xml that is under src :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
		"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
		"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

   		<mapping class="com.Person.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

I am getting the error :

In your hibernate.cfg.xml file, below line is not valid.
<mapping class="com.Person.hbm.xml"/>

For class attribute, use class name as below
<mapping class="com.fooPackage.AnotherModelClass" />

Or, use
<mapping resource="com/Person.hbm.xml"/>

Also, if you already mention the mapping file name or class name in the hibernate.cfg.xml, then below line is redundant.
Configuration cfg = new Configuration().addResource("person.hbm.xml").configure();

Thanks Mr. Reddy. This works now, just made 2 changes.

<mapping resource="com/Person.hbm.xml"/>

&

Configuration cfg = new Configuration().configure();
