Editorial Review:
The standard platform for enterprise application development has been EJB but the difficulties of working with it caused it to become unpopular. They also gave rise to lightweight technologies such as Hibernate, Spring, JDO, iBATIS and others, all of which allow the developer to work directly with the simpler POJOs. Now EJB version 3 solves the problems that gave EJB 2 a black eye-it too works with POJOs. POJOs in Action describes the new, easier ways to develop enterprise Java applications. It describes how to make key design decisions when developing business logic using POJOs, including how to organize and encapsulate the business logic, access the database, manage transactions, and handle database concurrency. This book is a new-generation Java applications guide: it enables readers to successfully build lightweight applications that are easier to develop, test, and maintain.

Good design starting point of lightweight J2EE projects  2007-12-03
With simple descriptives words and plain-text explanations this book shows many simple but practical ways of designing and implementing j2ee solutions using POJOs with those great design frameworks like spring and hibernate. This book can be considered as an detailed overview of how to build an enterprise lightweight J2EE projects including some introduction on some useful and practical patterns such as domain model pattern, POJO facade, persistence patterns, optimistics locking patterns etc. Together with spring and hibernate this book completes most of the great design prototypes of lightweight J2EE enterprise solutions. Highly recommended.
Perfect 2007-04-15
Got the book alle the way up to ice-cold Norway in no time. The packing was a bit ripped up; probably due to ice-bear attack.
Excellent Book 2007-02-22
I won't repeat what other reviewers already said.
The book is explains very good how to build enterprise apps using the pojo frameworks like spring, hibernate, jdo. It shows very nicely how to integrate these technologies. The code of the book is also awesome. It has a lot of examples.
Before reading this book I knew only hibernate. I saw the hard way that hibernate was not enough for building a complex project. So this made me to read this book. Reading this book I was forced to learn Spring too. When I tried to run the examples I saw that the examples project are built with Maven. I liked how simple and elegant the project was structured using Maven, so I learned Maven too(the book's code is an excellent example of Maven usage too).
I also saw that handling the concurrency in an (web) app is not an easy thing to do. The book has a good explanation of this topic in the last chapters. Chris is implementing some of the Fowler's patterns and that made me to get some more details about that so this is how I bought and read Fowler's book:Patterns of Enterprise Application Architecture which is by the way a excellent book too.
I highly recommend this book!
Good job Chris!
PS: too bad that I didn't have this book 2 years ago.
Must have book 2007-01-23
POJOs in Action describes how POJOs and lightweight frameworks such as Spring, Hibernate, JDO, iBatis make it easier and faster to develop testable and maintainable applications. You will also learn how to apply test-driven development and object design to enterprise Java applications. This book is all about implementing enterprise applications using design patterns and lightweight frameworks.
This book is for developers as well as architects who are experienced in developing enterprise applications in Java using EJB framework and want to know how to use POJOs and lightweight frameworks effectively.
This book consists of four parts. Part 1 which has 2 chapters is an overview of POJOs and lightweight frameworks. Part 2 has 5 chapters in which you will learn about a combination of options to design applications with POJOs and lightweight frameworks. In Part 3 you will learn about other approaches for designing the business and database tiers. Part 4's 3 chapter's looks at some important database-relates issues we normally encounter when developing enterprise Java applications. I should also mention that this book is not a complete reference for any of the frameworks like Spring, Hibernate, iBATIS etc.
Chris Richardson has done an outstanding job; this book deserves 5 out of 5. I wish I could have given more. Once I started reading the book, it was hard for me to put it down. This book teaches you when to use and when not to use each of the frameworks while many other books blindly advocate the use of their favorite frameworks. It is a must have book for every Java developer as well as architect. This is an excellent book, go get it; should be in your library.
Good overview of Spring, EJB, Hibernate  2007-01-03
Honestly I think this book is a little out of date, since the EJB 3.0 spec has come out. The author did go back and change some of the text to acknowledge that the EJB 3.0 spec is not as heavy weight as the older 2.1 spec, but was still heavier than Spring. I really would have liked to seen a deeper comparison between EJB 3 and Spring, but he seems to really push the Spring model.
That being said I think there are some excellent points the book brings out about the different Persistence layers and how debugging POJO's is so much easier than the alternatives.
