Hi

I am new to Hibernate.
I am trying to insert tha data in Oracle9i database through Hibernate3.1 by using the MyEclipse6 IDE.

error is:
"Exception in thread "main" org.hibernate.MappingException: Unknown
entityrg.hiber.test.DepthomeId "

Could you please check it and send the solution.

Hibernate class of a Hibappone.java file
------------------------------------------->

package org.hiber.test;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.*;
import org.hibernate.*;

public class HibAppOne {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

Configuration configuration=new Configuration();
configuration.configure();
SessionFactory sessionFactory=configuration.buildSessionFactory() ;
Session session=sessionFactory.openSession();

// Session session=org.hiber.test.OraSF.currentSession();
Transaction transaction=session.beginTransaction();
System.out.println("Up to transaction was created");

//Depthome depthome=new Depthome();
DepthomeId depthomeId=new DepthomeId();


depthomeId.setDno(new Long(1));
depthomeId.setDname("Bali");
depthomeId.setLoc("Vgya");

session.save(depthomeId);

transaction.commit();
session.close();


}

}

Let me know any solution for this.
