Hibernate works in Java Main Class but does not works if conneted to JSF form via Managedbean

Question

I am trying my first JSF Hibernate example. Below code inserts a record in table correctly if run it as Java Application in eclipse by copying it in Java Main Class (i.e.

public static void main(String[] args

However, it prompts errors when I try to run it by linking it with JSF Web-Form via Managed-Bean,

Project Settings: Dynamic Web Module version 3.0 JSF version 2.2 JPA Not enabled

package com.myFirstHibernate.eample;    
import java.util.List;   
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

import com.myFirstHibernate.eample.Student;
public class StudentDAO {

    public void insertOne() {
        //create session factory
        SessionFactory factory = new Configuration().configure("hibernate.cfg.xml").addAnnotatedClass(Student.class).buildSessionFactory();

        // create session
        Session session = factory.getCurrentSession();

        try {                           
            // create a student object
            System.out.println("Creating student object...");
            Student tempStudent1 = new Student("Andy", "Smith", "andy@gmail.com");
            //start a transaction
            session.beginTransaction();

            //save the student object
            System.out.println("saving the student...");
            session.save(tempStudent1);

            //commit transaction                
            session.getTransaction().commit();

            System.out.println("Insertion Done.");

        }

Errors:
