Summary: Excellent Beginner Reference
Review: A catalog of problem-solution patterns that pertain to J2EE. A great reference for beginners, instructing in some of the do's and don'ts of J2EE development. Much of the material presented has appeared on the Server Side, or in the J2EE core patterns from Sun, but this book presents the material in a concise easy to read format.General Topics include:
1. use of data transfer objects (DTOs)
2. architecture mechanisms to help promote team development
3. transaction and persistance patterns
4. key generation
5. code interaction patterns to help allevite performance bottlenecks.
6. multi-tier architectures and how to optimize them. There is also a short chapter on using JUnit and Ant to automate your environment, but they are so brief they really serve as more of a sales point to investigate these technologies rather than giving any real info on how to use them. Probably the most useful chapter was the last one which covered a number of tips and tricks to make EJB development easier. All in all as a beginner I got a lot of useful information out of this book. A seasoned developer will probably find a few things of interest, but will likely already know much of the material from the J2EE core patterns and personal experience.

Summary: Are you an EJB expert? Then this book is a must...
Review: Are you an EJB expert? Then this book is a must... Do you claim to be an EJB expert? If you do, you better make sure you understand the practices and patterns in this book. The next time you go on a job interview, the interview questions will be straight out of this book as it will become the de facto standard for how to design, architect and develop EJBs.

Summary: get it
Review: As a junior architect with no good mentor to learn from at my firm, this book is incredibly enlightening. (as well as the serverside) Cuts through all the garbage and gets to the point. I'm seeing some things I've thought of (and many I haven't), but was never able to confirm whether its "good practice" or not. I read half of it last night! the writing style is concise and the format is excellent - it lends to easy reading. it even comes with a pullout poster with quick refernce to all the patterns. I got this and the "Core J2EE patterns" book. EJB Design patterns is more hardcore. there is much value in the Core J2ee book, but this book, EJB design patterns, will make you know the why behind the what. Clearly, the authors have a wealth of real world experience and know how to convey their knowledge effectively.

Summary: 100+ pages of useful information
Review: As stated in the introduction, this book "was originally meant to be a chapter in Ed Roman's book (Mastering Enterprise JavaBeans), but as the chapter kept growing in size, we decided to promote it into its own book." This book contains about 120 pages of information that is quite useful and worth reading, plus another 85 pages of "filler," the only purpose of which seems to be to make the contents long enough to justify selling as a book in its own right. Perhaps it should have remained a chapter in Ed Roman's book, but it is worth reading. I would not suggest that anyone pay the full retail price... for this book. I rated it at four stars because the content is worth Amazon's discounted price... On a separate note, this book displays a lack of editing--or even simple proofreading--that has become too common in technical publications. The mistakes in this book go well beyond simple typographical errors and include incomplete sentences and even paragraphs that should have been removed before publication. Fortunately, it is possible to look past these flaws and find the value in the content.

Summary: The Perfect Partner for Mastering EJB
Review: Ed Roman's Mastering EJB has been my Bible on EJB, and now Marinescu is going on the shelf right next to Roman. The book goes beyond Roman to cover a bunch of difficult programming problems, more than any other book I've run across. No EJB library would be complete without it.

Summary: What an Awesome Book!!!-Premjith R(Datacard Software india)
Review: EJB design patterns by Floyd----What an Awesome Book it is...! i am an EJB architect working at Datacard Software India and i can't stop myself from writing out my excitement after reading the book..After developing a new Application(J2EE)server i thought i know a lot about EJB and J2EE, but now i realise i wouldn't have been anything without this book..Simply Awesome...What a superb way of explaining the things! Great...
I was only aware of Session Facade pattern but his book has sharpened my skills to a very splendid stage..As it is always true the really good design is the key of the success of any product ,this design patterns will help all developers to be real excellent and wonderful architects,i am pretty sure...Thanks Floyd

Summary: A must have for all EJB architects and developers
Review: Fascinating, inspiring and amazing!! This book is worth every penny you pay. All EJB developers are already familiar with the ultimate J2EE resource, theserverside.com. All architects and developers frequent it for the latest and the best feedback on all things related to EJB. Take the architect of that site, who also is the chief architect of The Middleware company, and take some serious developers from the J2EE community and the outcome is a book that addresses the needs of most EJB architects. The book is divided into 2 parts, the first part describes the EJB Pattern Language and the second part describes the best practices for EJB design and implementation. The first part catalogs the basic EJB design patterns. Analogous to describing the various tools in the toolset, Floyd takes us through a myriad of EJB patterns, most of which are already known. These patterns are tried and tested strategies that have been working in many J2EE Systems. The second part is the real value in the book where EJB design strategies, idioms, tips, do's and don'ts specific to EJB projects are discussed to alleviate the problems of most developers. This section arms us with the tools and the knowledge to get the work done. The requirement to EJB pattern-driven design discusses how a set of real-world requirements are realized using as a pattern-driven architecture.
The book also provides a EJB design patterns chart that provides a snapshot of all the design patterns discussed. This chart adorns the wall in front of me, to provide a quick reference at all times. This book is a great in-depth reference for any EJB developer on advanced EJB design. Those that are new to EJB design patterns may find this book a little intimidating; then again this book is not intended for those that are just getting started with J2EE. Familiarity with Sun's J2EE patterns will help you really appreciate the practical value of this book.
