✦ Synopsis

Beginning Hibernate, Second Edition is ideal if you’re experienced in Java with databases (the traditional, or ''connected,'' approach), but new to open source, lightweight Hibernate—the de facto object-relational mapping and database-oriented application development framework.This book packs in brand-new information about the latest release of the Hibernate 3.5 persistence layer and provides a clear introduction to the current standard for object-relational persistence in Java. And since the book keeps its focus on Hibernate without wasting time on nonessential third-party tools, you’ll be able to immediately start building transaction-based engines and applications.Experienced authors Dave Minter and Jeff Linwood provide more in-depth examples than any other book for Hibernate beginners. The authors also present material in a lively, example-based manner—not a dry, theoretical, hard-to-read fashion.What you’ll learnHow to build enterprise Java-based transaction—type applications that access complex data with Hibernate, including Software as a Service (SaaS)How to work with Hibernate 3.5Where to integrate into the persistence lifecycle, including cloud application implicationsHow to map using annotations, Hibernate XML files, and moreHow to search and query with the new version of HibernateWhen to integrate with Spring, Grails, and moreWho this book is forThis book is for Java developers who want to learn about Hibernate
