Hi All,

I'm new to Hibernate.I'm trying to compile a sample Hibernate program(with a pointbase connection).I'm getting the below error.Can anybody help me in this case.

Exception in thread "main" java.lang.NullPointerException
at roseindia.tutorial.hibernate.FirstExample.main(FirstExample.java:38)

The java code is as below.


package roseindia.tutorial.hibernate;

import org.hibernate.*;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


/**

* Hibernate example to inset data into Contact table
*/
public class FirstExample {
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();


System.out.println("Getting session factory");


session =sessionFactory.openSession();


}catch(Exception e){
System.out.println(e.getMessage());
}finally{
// Actual contact insertion will happen at this step
session.flush();
session.close();

}

}
}


Thanks in advance

If you do session.Close() no need for session.flush().
First check whether the session you got from openSession is null or not.
2nd remove the sessionl.flush from code and see
 
Would you turn that thing down? I'm controlling a mind here! Look ... look at the tiny ad ...
