My hibernate.cfg file is

My Mapping File is:

    private String roll;
    private String phone;
    /** Getters and setters omitted **/
}

My Tester class is:

public class SimpleTest {

  public static void main(String[] args) {

    Configuration cfg = new Configuration();
    cfg.configure("hibernate.cfg.xml");
    SessionFactory factory = cfg.buildSessionFactory();
    Session session = factory.openSession();
    Student student = new Student();
    student.setName("Gourab");
    student.setRoll("101");
    student.setPhone("8888");
    student.setDegree("B.E");

    Transaction tx = session.beginTransaction();
    session.save(student);
    System.out.println("Object saved successfully.....!!");
    tx.commit();
    session.close();
    factory.close();
  }
}

Answer 1

I copied every file from your page as above and created a new project. Please follow the below structure to avoid the above exception.

public class App 
{
public static void main( String[] args )
{
    System.out.println("Maven + Hibernate + MySQL");
    Session session = HibernateUtil.getSessionFactory().openSession();

    session.beginTransaction();
    Student st1 = new Student();

    st1.setName("srinivas");
    st1.setPhone("99");
    st1.setRoll("123");


    session.save(st1);
    session.getTransaction().commit();
}
}

Answer 2

Hibernate can't parse your hibernate.cfg.xml .

hibernate-core-3.6.9.Final.jar has a file with DTD hibernate-core-3.6.9.Final/org/hibernate/hibernate-configuration-3.0.dtd

Check this file inside hibernate-core-3.6.9.Final.jar .

You need to have the same DTD as hibernate-configuration-3.0.dtd has.

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

Looks like you already have it.

May be you have other hibernate-core jar in the class path with other DTD.

Could you try to check your .jar again? I try to execute your project SimpleTest.java with my .jar . It is work. Please take a look
