Hibernate help

I am trying to write some data to my database. I get the following error:

Hello

Exception in thread "main" java.lang.NullPointerException
at com.marketecho.mecap.WritingRecord.main(WritingRecord.java:38)

My code is the following:

 
package com.marketecho.mecap;
 
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
 
 
public class WritingRecord  {
  public static void main(String[] args) {
  Session session = null;
    System.out.println("dummy line\n");
    try {
     // This step will read hibernate.cfg.xml and prepare hibernate for use
    System.out.println("Hello\n");
  SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
   session = sessionFactory.openSession();
   org.hibernate.Transaction tx = session.beginTransaction();
 
      //Create new instance of Contact and set values in it by reading them from form object
      System.out.println("Inserting Record");
      Customer cust = new Customer();
      cust.setCustomerId(3457);
     cust.setCustomerFName("Deepak");
     cust.setCustomerLName("Kumar");
    cust.setEmail("[e-mail]");
      session.save(cust);
      tx.commit();
      System.out.println("Done");
     
    } 
   catch(Exception e) {
      System.out.println(e.getMessage());
    } 
   
    finally {
      // Actual contact insertion will happen at this step
    System.out.println("Hello\n");
       session.flush();
     session.close();
    }  
  }
} 

It gives me null pointer exception at line session.flush().

So the Session is null. Did either of these lines work?

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

This line:

An AnnotationConfiguration instance is required to use <mapping clazz="com.marketecho.mecap.Users"/>

suggests they didn't.

What can I do about it? any suggestion please.

[Farhan Chowdhury]

After SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
It catches exception prints out the following line
An AnnotationConfiguration instance is required to use <mapping clazz="com.marketecho.mecap.Users"/>
Then since session is null, it gets null pointer excepetion at
line session.flush();

Any suggestion what can I do?
