JBoss AS 5 Development ReviewBefore reading this book, I already knew the author, Francesco Marchioni, because of his web site which is dedicated to JBoss. So it was with enthusiasm that I wished to get a copy of the book and I was not disappointed. Indeed the book is like the web site : practical, rich in samples and useful information.
The book uses JBoss 5. It was published in december 2009, when the first version of JBoss 6 was becoming available and starting to implement Java EE 6. But the book is still up to date since it describes functionalities of JBoss that are more or less independant of the versions of Java EE.
The book is made of 14 chapters. As usual with the books from the Packt Publishing collection, there is a resume at the end of each chapter which recapitulates the main subjects.
The first 3 chapters describe the installation of JBoss, the new features and the configuration of services (logs, database connection, transactions, use of the JMX console and the administration console based on Jopr).
Chapter 4 is dedicated to the EJB container in JBoss since the session beans (EJB 3) are being developed. There is coding, theoretical explanations (for instance the session beans life cycle) and practical explanations (for instance how to configure the size of the pool of stateless session beans in JBoss).
Chapter 5 is about the persistence and a project is developed in Eclipse, using entity beans and the Java Persistence API (JPA).
Chapter 6 uses JSF 1.2 for the creation of a web application. The author describes the Web server inside JBoss and which uses Apache Tomcat.
Chapter 7 uses JMS with Message-Driven Beans and JBoss Messaging which replaces JBoss MQ. Again, there are nice explanations : theoretical and practical.
Chapter 8 shows the use of Hibernate with JBoss Tools / Hibernate Tools.
Chapters 9 to 12 go into the heart of JBoss AS with explanations of JMX, the MBeans and the management of resources from the administration console. Web Services are developed and deployed in JBoss WS.
Clustering of JBoss AS servers is not forgotten : there are explanations on the configuration needed for load balancing and the use of JBoss Cache to synchronise data in a cluster, among many other explanations.
Finally I found chapters 13 and 14 on security very complete. The author writes about everything : JAAS, JBossSX, certificates, securing EJB, Web Services encryption ...
What I liked the most : The many illustrations (of the console, the file system structure in JBoss, the screenshots of Eclipse ...), the concrete samples, the simple explanations.
What I liked the least : one might have liked to read more details about certains subjects but that is not a negative thing because the author gives the basic explanations needed to investigate further if necessary.JBoss AS 5 Development OverviewThis book follows a tutorial-based approach starting with simple examples, which are enriched in the following chapters as new topics are introduced. Each chapter provides clear instructions and detailed screenshots, as the user approaches a new facet of the development environment. Most complex topics have been explained using practical examples, which will help you to master JBoss AS development. If you are a Java architect or developer who wants to get the most out of the latest release of the JBoss application server or a JBoss administrator who wants a clear and simple reference for JBoss services, this book is for you. You are not expected to have accumulated experience on the application server though you must know the basic concepts of Java EE.

Tomcat 6 Developer's Guide ReviewI've been writing Java webapps and using tomcat on production for the past 5 years.
This book is the best and most complete tomcat analysis book I've read. It is for developers and sysadmins, and it gives both the high level and very detailed views of the system. It starts by taking you through building your own tomcat from source (using ant and eclipse) and extensively explains the servlet spec, JNDI and all parts of the container. It also unravels a very dark corner of java (which directly relates to web containers), the classloader, in a way which does make sense.
The book shows all the configuration details, in a pragmatic way. Some of the options and usage patterns are not that well written on the official tomcat documentation site.
While reading it I improved my tomcat configuration on production by reducing the memory footprint of the container. I also vastly improved my understanding on the servlet spec, web containers and tomcat itself so I had a chance to improve parts of my production code.
The book is very well written and the only disadvantage is that at some parts you feel like the author steps through the code describing it in English. Fortunately these parts are few and short.
All in all, the amount of knowledge this book gives is great and nowhere else to be found is such cohesive way.
Tomcat 6 Developer's Guide OverviewThis book taps into the author's wide experience as an architect and programmer to explore Tomcat from the ground up. Each major component of Tomcat is covered in careful detail, both from a conceptual and an implementation perspective. Written with detailed explanations and lots of screenshots, the book covers its topics in a concise, practical, and understandable manner. This book is intended for web developers who want to take their programming skills to the next level, and for server administrators who want to get a better understanding of the container software they manage. This book will give you an expert's understanding of every component that contributes to the overall request processing capabilities of Tomcat. In addition, the concepts you learn will be general enough to be carried over to other servlet containers. This book is also a good starting point for developers who want to understand how high availability and high performance software, such as Tomcat, are designed. If you wish to contribute to the Tomcat project, then this is an ideal book for you. Prior knowledge of the Java programming language, and web development on the Java platform is assumed.

The Java EE 6 Tutorial: Basic Concepts (4th Edition) (Java Series) Review"The Java EE 6 Tutorial Basic Concepts" is the official tutorial covering all the Java EE technologies. I can't believe it has been 4 years since I read the Java EE 5 version. Last time I remarked 1300 pages was too heavy. Version 6 is split into two volumes which is nice because you can carry it around. The basic concepts one covers web/ejb/jpa/web services.
"As part of Sun's 'The Java Series' this book has the same content as you can find online. Why buy a book you can get for free? Convenience!! You can take it anywhere and read it anytime." - Dave Vick - JavaRanch Review of the J2EE 1.4 version. This benefit is back.
Other dislikes:
confusion between Oracle/Sun.. For example "Oracle web site" [...]". I'd like to see mention of a transition.
wasn't clear what was new in Java EE 6.
as in past editions, it reads better online than printed.
extensive forward references and lots of repetition. For example, they repeat the six steps to open a NetBeans project 12 times!
many examples didn't explain how/why to do something - like whether to call a web service directly from a JSP.
I did like the walk-through of certain technologies. And the good quality cover paper that doesn't get damaged even if you spill juice on it!
There were good diagrams and charts and good case studies along with several excellent chapters. While I like this version better than #5, I would say to read the pieces you are interested in online and spend your money on a different book.

Beginning Java EE 6 Platform with GlassFish 3: From Novice to Professional (Expert's Voice in Java Technology) Reviewalthough the title of the book starts with "Beginning", it doesn't mean that it will actually start from scratch!! this book is for professionals only and it assumes that you already know Java EE 5 ! although the author did try to write some topics for the beginners, but it seems that he had put them there just for the sake of the book title :)
also, when you get this book, don't expect to find "details"! it is very hard to talk about the whole Java EE 6 in one single book! indeed, the book shows you the "new" features in Java EE 6 but it doesn't go deep into anything!
so, the book is not for beginners cause it assumes (even if they didn't say so) that you know Java EE 5 .. and it is not for professionals as it's not saying much!
AT THE END:
if you know Java EE 5 .. get this book .. it will tell you what's new in Java EE 6 and you are good to go ! if you don't know Java EE 5, keep looking for a good book for beginners
hope this helpsBeginning Java EE 6 Platform with GlassFish 3: From Novice to Professional (Expert's Voice in Java Technology) OverviewEnterprise Java' platform, Java EE 6, is getting a facelift from Sun! Beginning Java EE 6 Platform with GlassFish 3 is the first tutorial on the new Java EE (Enterprise Edition) platform, and could be one of the first books to the market all together on the new Java EE 6.

Eclipse Web Tools Platform: Developing Java™ Web Applications ReviewThe reason I bought this book was so I could quickly get through some hands-on examples and see the power of WTP. Also, I thought it would be really helpful to see various web development tools through the lens of Eclipse development. After going through it, though, I'm afraid I can't recommend the book for those purposes.
But first, let me applaud the web development "wisdom" portions of the book. There are some really good "why are we doing this?" and "why are we doing it this way?" explanations in this book. Nothing to do with WTP, really, but these portions of the book were very well done.
The majority and purpose of the book are the hands-on exercises. Here's where I had some issues. Throughout the exercises, the reader is always being asked to go out and download some tool or another. I spent way too much time at update sites, trying to get the right versions of things. I would rather all of this be established up-front. Just say "if you want to do all of the exercises, download these specific versions of these 8 tools". Later, there can be some explanation as to why those tools over others, but lets get a platform that's going to do everything, and not sprinkle installation issues throughout. In fact, I think that in an Eclipse book, they instructions should say, "start with a clean install of (some version of Eclipse) and build it with (these versions of these plugins), and you will be able to do every exercise."
I know it's not the job of the authors of this book to detail a tool's installation, but a line like "check the (some tool) documentation for the exact list" is a cop out. Presumably, the authors just got done using the list, so a few words as to how to find the list within the documentation would be really helpful. With a little guidance, digging time could be reduced from an hour to two minutes.
The exercises had separate iterations, which I found helpful. I did run into discontinuities that required some improvisation, though. I'm pretty sure that nobody sat down with an empty machine, installed all of the tools and ran all of the exercises, start to finish. Or if they did, the book didn't get updated.
The book was written using WTP 1.5, EJB 2.1, etc. These are older versions than what's currently available, but it's not a problem to run through the exercises with the older versions. The problem comes at the end of the exercise when they give you a "tease" about how cool the next version is. I resisted temptation for almost the whole book but finally I grabbed some updated versions to try out the cool new stuff! Bad idea. I backed-up to earlier exercises, and although I was able to replicate most of them under the newer versions of things, there's not enough detail to get through quickly (lots of trial and error). And when I was finished, I wasn't convinced it was an optimal result. But I just couldn't sit still with the old versions when the authors were plugging the new versions.
A picky issue I have concerns references to other books. I don't think they belong in the main text, really. They wouldn't even need footnotes. Just a recommended reading by chapter would be sufficient. If you are more of an academic than someone who needs to apply this stuff quickly, maybe reading these other books might be a possibility, but I'll tell you I'm not going to make time to read a 9 year old EJB book!
I'm not sure that pitching to a WTP user and a WTP volunteer developer in the same book was really in the flow of the book. This is a picky one too, and there weren't that many pages dedicated to this topic. I suppose there's a need to recruit, it's just that I'm not sure the audience overlaps very much.
The bottom line for me is that a book should simplify the task of setting up the environment so that I can concentrate on the "why" and "how" of coding. Although I wouldn't have enjoyed the "wisdom" and other continuity the book offered, I don't think I saved any time on the development environment. I spent as much time tinkering with the development environment as I would have if I had just grabbed 6 or 8 tutorials from 6 or 8 different authors off of the internet.Eclipse Web Tools Platform: Developing Java™ Web Applications OverviewDiscover WTP, the New End-to-End Toolset for Java-Based Web Development TheEclipse Web Tools Platform (WTP) seamlessly integrates all the toolstoday's Java Web developer needs.
