this is my test file of the hibernate:

package test;

import hibernate.ThreadLocalSession;
import model.User;

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

public class firstName {

/*
* Hibernate example to inset data into Contact table
*/
public static void main(String[] args) {
Session ses = null;

try{
ses = ThreadLocalSession.currentSession();
//Create new instance of User and set values in it by reading them from form object
System.out.println("Inserting Record");
User user = new User();
user.setEmpNo("002");
user.setFirstName("Hii");
user.setLastName("Ling");
user.setDesignation("null");
user.setCompany("xyz");
user.setDepartment("abc");
user.setExtNo("375");
ses.save(user);
System.out.println("Done");
}catch(Exception e){
System.out.println(e.getMessage());
}finally{
// Actual user insertion will happen at this step
ses.flush();
ses.close();

}

}
}

the error shows when i run the java application is as shown below:

** 2
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
java.lang.NullPointerException
at test.firstName.main(firstName.java:36)
Exception in thread "main"

can anyone comment on this??

your ThreadlocalSession class may be trying to find session factory from jndi . in that case, the error may be solved to specifying the JNDI context properties , and INCLUDE the context factory class in the class path
