I am running InheritanceType.TABLE_PER_CLASS and saving data like
Session session=getSession();
session.beginTransaction();
Employee e=new Employee(1,"james",25);
session.save(e);
Manager m=new Manager(1,"james",25,"SC","ABC");
session.save(m);
session.beginTransaction();
session.getTransaction().commit();
Session session=getSession();
session.beginTransaction();
Employee e=new Employee(1,"james",25);
session.save(e);
Manager m=new Manager(1,"james",25,"SC","ABC");
session.save(m);
session.beginTransaction();
session.getTransaction().commit();

You need to use as
session.flush();
session.clear();
your code should look like
Session session=getSession();
session.beginTransaction();
Employee e=new Employee(1,"james",25);
session.save(e);
Manager m=new Manager(1,"james",25,"SC","ABC");
session.flush();
session.clear();
session.save(m);
session.beginTransaction();
session.getTransaction().commit();
