Pro JPA 2

Pro JPA 2, 9781430249269 (1430249269), Apress, 2013

Pro JPA 2, Second Edition introduces, explains, and demonstrates how to use the new Java Persistence API (JPA) 2.1 from the perspective of one of the specification creators. A one-of-a-kind resource, it provides both theoretical and extremely practical coverage of JPA usage for both beginning and advanced developers.

Authors Mike Keith and Merrick Schincariol take a hands–on approach, based on their wealth of experience and expertise, by giving examples to illustrate each concept of the API and showing how it is used in practice. The examples use a common model from an overriding sample application, giving readers a context from which to start and helping them to understand the examples within an already familiar domain. After completing the book, you will have a full understanding of JPA and be able to successfully code applications using its annotations and APIs. The book also serves as an excellent reference guide during initial and later JPA application experiences.

Hands-on examples for all aspects of the JPA specification
Expert insight about various aspects of the API and when they are useful
Portability hints to provide increased awareness of the potential for non–portable JPA code

Who this book is for

The book generally targets enterprise and persistence developers who fall in one of three categories:

Those who are new to persistence; we will offer an introduction to persistence and to the basic concepts so these readers can have solid base from which to become proficient at JPA.
Those who know and/or use existing ORM persistence products such as Hibernate or TopLink/EclipseLink.
Those who have already used JPA and want to learn about newer features introduced by JPA 2.1, or have a good reference book to consult when they develop JPA applications.

In general, we assume that the reader is knowledgeable with Java, SQL, and JDBC, and has a little knowledge of Java EE.
