learning Hibernate and its really making me crazy i am trying to persist an entity class along with its chilren and here is the method which is doing this for me
log.info("About to persist the given Entity instance");
Session session=HibernateSessionFactory.getSessionfactory().openSession();
Transaction tx=session.getTransaction();
try{
tx.begin();
session.saveOrUpdate(entity);
tx.commit();
}
catch(Exception e){
tx.rollback();
}
finally{
session.close();
}
return entity;
}
everything seems ok and here is the console output i am totaly cluless hibernate is not showing any exception nor its saving anything in the database
