As per http://www.hibernate.org, Hibernate is a powerful, ultra-high performance object/relational persistence and query service for Java. Hibernate gives you the option to code and work with Java and use Hibernate's capabilities to interact with the database. No need to write SQL in your Java code. You work with Java objects and Hibernate does the rest.

In this "Quick Hibernate" series of articles, Satish Talim gets you started with Hibernate. Satish's hands-on approach should have you developing with Hibernate in no time.

Quick Hibernate
By Satish Talim

We need a means of taking information from a SQL database and turn it into Java objects, and vice-versa. The general problem is known as Object/Relational Mapping. Hibernate is a lightweight O/R mapping service for Java and gives you the means for persisting your Java objects to and from an underlying database. Rather than you writing the SQL and converting queries to and from first class objects, Hibernate can take care of all this for you. You only concern yourself with the objects, Hibernate worries about the SQL and making sure things end up in the right tables.

There are many books and articles available on Hibernate and what I want to do here is quickly get you started with Hibernate. I want to take this opportunity to thank Glen Smith for showing me the quick way to get started with Hibernate and this blog is based on that and dedicated to him.

Quick Installation and Setup

• Install J2SDK 1.4.2
• Install Ant
• Go to http://www.hibernate.org/ and download Hibernate
• Install Hibernate by unzipping the file hibernate-2.1.6.zip to drive say F:
• Setup a Project Hierarchy by doing the following  Create folder F:hlogin and then create sub-folders F:hloginsrc and F:hloginlib
• Copy all the contents of F:hibernate-2.1lib to F:hloginlib
• Copy hibernate2.jar to F:hloginlib
• The example classes we are going to create are all going to reside in the folder F:hloginsrccomtalimdemo. Create these sub-folders.

?

At the folder F:hlogin type ant

To run your Hibernate programs

At the folder F:hlogin type ant run
