Title: POJOs in Action Dec 2005
Author: Chris Richardson
Format: PDF
Publisher: Manning
POJOs in Action is a practical guide to using POJOs and lightweight frameworks to
develop the back-end logic of enterprise Java applications. These technologies are
important because they dramatically simplify how you build an application’s busi-
ness and persistence tiers. This book covers key lightweight frameworks: Spring,
JDO, Hibernate, and iBATIS. It also covers EJB 3, which embraces POJOs and
some of the characteristics of lightweight frameworks.
In this book you will learn how to apply test-driven development and object
design to enterprise Java applications. It illustrates how to develop with POJOs and
lightweight frameworks using realistic use cases from a single example application
that is used throughout the book. It even implements the same use case using mul-
tiple approaches so that you can see the essential differences between them.
A key message of POJOs in Action is that every technology has both benefits
and drawbacks. This book will teach you when to use—and when not to use—
each of the frameworks. For example, although the emphasis is on the Spring
framework and POJOs, this book also describes when it makes sense to use EJBs.
It explains when to use an object-oriented design and an object/relational map-
ping (ORM) framework and when to use a procedural design and SQL directly.
This sets POJOs in Action apart from many other books that blindly advocate the
use of their favorite framework.
Enterprise Java frameworks are constantly evolving. While I was writing this
book, all of the frameworks I describe had several releases. EJB 3 appeared, albeit
in draft form. And between the time this book is printed and the time you read it,
some enterprise Java frameworks will have evolved further yet. But the good news
is that this book will remain relevant. POJOs and nonintrusive lightweight frame-
works are here to stay.
Regardless of how the frameworks evolve, there are some key concepts that will
not change. First, it’s vital that you objectively evaluate the pros and cons of a
framework and not be swayed by clever marketing. Second, POJOs and nonintru-
sive frameworks are a good thing. You want to avoid coupling your business logic
to an infrastructure framework, especially if it slows down the edit-compile-debug
cycle. Third, testing is essential. If you don’t write tests, then you can’t be sure that
your application works. And you must be able to write tests, so designing for test-
ability is also important. Finally, as Albert Einstein said, “Everything should be
made as simple as possible, but not simpler.”
