Hi

I am using jdk 6.0, eclipse 3.2 and hibernate 3.
When i am running client program it gives me this error please help me

Could not parse mapping document from resource user.hbm.xml
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" java.lang.NullPointerException
at UserClient.main(UserClient.java:39)

This is my hibernate.cfg.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

</hibernate-configuration>


This is my user.hbm.xml file:

<?xml version="1.0"?>

This is client program:

import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


public class UserClient {
public static void main(String[] args) {
Session session = null;

try{
// This step will read hibernate.cfg.xml and prepare hibernate for use
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
session =sessionFactory.openSession();
//Create new instance of Contact and set values in it by reading them from form object
System.out.println("Inserting Record");
User user = new User();
user.setUserId("u1");
user.setUserName("abc");
user.setUserFirstName("xyz");
user.setUserLastName("ag");
user.setUserAddress("te");
user.setCity("S");
user.setZipCode("520");
user.setContactNo("839423");
user.setUserEmail("jiewo@df");
user.setUserCreationDate(new Date());
user.setUserRole("Manager");

session.save(user);
System.out.println("Done");
}catch(Exception e){
System.out.println(e.getMessage());

}finally{
// Actual contact insertion will happen at this step
session.flush();
session.close();


}

}
}

Well, where is located your User class? (Fully Qualified Name).
