[Java] Hibernate basics with Eclipse

This entry proxies for a series of tutorials which introduces the basics of Hibernate for utter beginners. I only assume that the reader have a grasp of the Java and SQL semantics. Obviously, there is more to Hibernate than we have covered in these tutorials. A good sequel for these tutorials would cover the use of annotations to describe entity classes and their attributes. Other related entries would include lazy initialization, caching and some other mechanics regarding the use of Session objects, as well as the integration of Hibernate in enterprise applications.
It is worth mentioning that these tutorials are basically my notes when I was learning Hibernate.

2. Source code

This archive contains full Eclipse projects for the functional parts of the code used in the examples: http://sourceforge.net/projects/pnc-hib-basics-ex/files/. You need to populate lib directory with Hibernate jar files and your favorite DBMS's JDBC driver. Then, you have to edit hibernate.cfg.xml to use your database connection settings.
These projects were tested under a Linux environment (Debian Wheezy) using the software configuration mentioned in the first tutorial.

Thank you!
