Harnessing Hibernate is an ideal introduction to the popular framework that lets Java developers work with information from a relational database easily and efficiently. Databases are a very different world than Java objects, and they often involve people with different skills and specializations. With Hibernate, bridging these two worlds is significantly easier, and with this book, you can get up to speed with Hibernate quickly.

Rather than present you with another reference, Harnessing Hibernate lets you explore the system, from download and configuration through a series of projects that demonstrate how to accomplish a variety of practical goals. The new edition of this concise guide walks you through Hibernate's primary features, which include mapping from Java classes to database tables, and from Java data types to SQL data types. You will also learn about Hibernate's data query and retrieval facilities, and much more.

By reading and following along with the examples, you can get your own Hibernate environment set up quickly and start using it for real-world tasks right away. Harnessing Hibernate teaches you how to:

Perform Object/Relational mapping
Work with persistent data from Java code
Work with groups and relationships between objects
Extend Hibernate's rich type support for your own needs
Simplify query creation using criteria and examples
Use the Hibernate Query Language (HQL) and understand how it differs from SQL
Use Hibernate in conjunction with Spring
Use Hibernate in conjunction with other packages, such as the Stripes web framework and the Eclipse IDE

Once you're past the first few chapters, you can jump to topics that you find particularly interesting or relevant. All background material and explanations of how Hibernate works and why is in the service of a focused task. Source code can be downloaded from the book's website.

If using SQL is an uncomfortable chore, Harnessing Hibernate offers you an effective and trouble-free method for working with the information you store in your applications.

The animal on the cover of Harnessing Hibernate is a hedgehog, a small mammal in the family Erinaceinae. There are 16 hedgehog species in 5 genera, found throughout parts of Europe, Asia, Africa, and New Zealand. Some of these species are: the four-toed hedgehog (south-Saharan Africa); the long-eared hedgehog (Central Asia); the desert hedgehog (Africa and the Middle East); and the bare-bellied hedgehog (India). The different species vary in size, measuring 5 to 12 inches long and weighing 15 to 40 ounces. The most common domesticated hedgehog, known as the four-toed or African pygmy hedgehog, is smaller than its European cousins and has become a popular pet in many countries. The name hedgehog first came into use in the mid-15th century--"hedge" because it roots through undergrowth, and "hog" because of its pig-like snout. Hedgehogs are also known as urchins, hedgepigs, and furze-pigs.

The hedgehog's most distinctive feature is its spines, which grow everywhere on its body except its face, legs, and belly. When threatened, it rolls into a tight ball so that all of its spines point outward, presenting a barbed surface to predators. These spines are stiff, hollow hairs made of keratin and are very strong. Unlike a porcupine's quills, they do not fall out, except when a hedgehog sheds its baby spines during a process known as "quilling."

Hedgehogs eat small invertebrates such as frogs, slugs, and earthworms. Some hedgehogs have immunity to toxins and can eat bees, wasps, and venomous snakes. Being nocturnal, they sleep for most of the day in grass or under rocks or in holes in the ground. Although all hedgehogs can hibernate, not all do-hibernation depends on factors such as location, temperature, and abundance of food. In England, Bonfire Night celebrations on November 5th pose a particular risk to hedgehogs, who often sleep in the wood piles used for bonfires. Wildlife protection groups now warn the public to inspect their wood piles before lighting fires in order to protect hibernating hedgehogs.
