Hibernate “Session” is the persistence manager for the application.

The instance of the Session class shall be retrieved from the “SessionFactory” class.

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

The call to the configure() method loads the hibernate.cfg.xml file and initialize the Configure instance.

SessionFactory is immutable class. SessionFactory is usually only build once at the start of the servlet.

Hibernate can access Public,Prive,Protected fields/methods.

No argument constructor is mandatory for each class as Hibernate has to create instance of the class using Java Reflections.

The Type attribute  in the mapping file is not the type of Java or SQL. It is the mapping data type of hibernate.

The default column mapping is to name field of the property in not mentioned explicitly.
