Java Persistence and Hibernate book

I publish a continuously updated ebook on Hibernate and Java Persistence for more than 3 years by now.

In 2007 I have translated this ebook for the well known German publisher Galileo Press into German language. It is available as paper book in German language and can be purchased in book shops or online at Galileo Press: http://www.galileocomputing.de/978?GPP=hibernate

Hibernate and Java Persistence eBook

Extensive, easy-to-follow introduction to Hibernate. It starts from the beginning and will still be a great help when you deal with performance tuning or Hibernate architecture.

It covers the current Hibernate version 3.3 and is constantly updated. It is full of examples showing you how things look like in real code. What do you get?

• eBook in PDF Format
• You can choose the number of updates of the book.
• The book has more than 240 pages. The format is Din A4.
• More than 20 sample projects
• More than 26 samples showing either mappings, Hibernate filter, named queries or other things
• About 60 mapping variants (1:1, 1:n, m:n, ternary, uni/bidirectional, components, entity associations, inheritance, ...)
• Mappings are explained for Annotations and XML including query examples
• Taking care of the developer and explain problem zones in detail
• Focus on best practices
• Real projects showing how to integrate Hibernate with other technologies and craft propper architectures

The book is provided as PDF and is lizenzed to a single person only.

Ordering can be done in my Online Shop. The table of content can be found below.

Explanations with complete working examples

Whenever something is explained you will find a complete sample application. If a specific mapping is demonstrated you can find a sample application, too. It shows how to insert, update, delete or query the classes included in this mapping.

Larger sample applications show the implementation of real applications using Hibernate in detail. Each application has an increasing complexity.

Cache configurations, deployment configurations for particular application server rounds off the examples.

Altogether the book provides about 20 mapping examples + variations, 4 real projects and some smaller projects showing a specific configurations.

Hibernate Project Setup

Examples to set up Hibernate projects with Eclipse and MyEclipse. Automatic generation of Hibernate mappings from existing databases.

Potential problems are investigated in detail

Hibernate has some problem zones where you can easily make mistakes. These are covered in detail to help you to avoid these problems. Some topics are LazyLoading, Session and transaction handling, optimistic concurrency and version handling.

Best Practices

One chapter is completely focussing on how to implement well designed Hibernate applications. DAO patterns and business layers are discussed. Pros and cons and the logic behind this structure are explained.

Focus on important features

Deliberately, I did not explain some rare concepts which I consider to be either not stable or very rarely used. Instead I referred to the corresponding chapters of the Hibernate reference - the documentation available with Hibernate. In my opinion the Hibernate reference is far too complex for people learning Hibernate. However, it is a valuable resource for people who already know Hibernate.

What this book is not?

The texts are short and frequently you are referred to parts of sample applications. If you prefer larger narrative parts you should not read this book.
