I have implemented basic hibernate example from your site . In console i got output but database is not affected. hbm.xml

<id name="id" type="long"  column="id">
    <generator class="Assigned" />
 </id>

<property name="name" >
    <column name="name" />
</property>

<property name="sex" >
    <column name="sex" />
</property>
 </class>

Main package com.tcs; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class Imp { public static void main(String[] args) { Session session = null; try{ SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); session =sessionFactory.openSession(); System.out.println("Inserting Record"); Bookdetails book = new Bookdetails();

      book.setname("venkat");
      book.setid(12102);
      book.setsex("male");
      session.save(book);
      System.out.println("Done");
      }catch(Exception e){
      System.out.println(e.getMessage());
      }
      finally{
          session.flush();
          session.close();
          }
      }
 }
