Consisting of a number of well-known open source products, JBoss is more a family of interrelated services than a single monolithic application. But, as with any tool that's as feature-rich as JBoss, there are number of pitfalls and complexities, too.

Most developers struggle with the same issues when deploying J2EE applications on JBoss: they have trouble getting the many J2EE and JBoss deployment descriptors to work together; they have difficulty finding out how to get started; their projects don't have a packaging and deployment strategy that grows with the application; or, they find the Class Loaders confusing and don't know how to use them, which can cause problems.

JBoss at Work: A Practical Guide helps developers overcome these challenges. As you work through the book, you'll build a project using extensive code examples. You'll delve into all the major facets of J2EE application deployment on JBoss, including JSPs, Servlets, EJBs, JMS, JNDI, web services, JavaMail, JDBC, and Hibernate. With the help of this book, you'll:

• Implement a full J2EE application and deploy it on JBoss
• Discover how to use the latest features of JBoss 4 and J2EE 1.4, including J2EE-compliant web services
• Master J2EE application deployment on JBoss with EARs, WARs, and EJB JARs
• Understand the core J2EE deployment descriptors and how they integrate with JBoss-specific descriptors
• Base your security strategy on JAAS

Written for Java developers who want to use JBoss on their projects, the book covers the gamut of deploying J2EE technologies on JBoss, providing a brief survey of each subject aimed at the working professional with limited time.

If you're one of the legions of developers who have decided to give JBoss a try, then JBoss at Work: A Practical Guide is your next logical purchase. It'll show you in plain language how to use the fastest growing open source tool in the industry today. If you've worked with JBoss before, this book will get you up to speed on JBoss 4, JBoss WS (web services), and Hibernate 3.

5.0 out of 5 stars This book truly is a practical guide, March 21, 2006

This review is from: JBoss at Work: A Practical Guide (Paperback)

The subtitle for this book is "A Practical Guide." That subtitle is perfect. This is one of the most immediately useful and practical books I've read in a long time. I began using JBoss at the same time I started reading this book and I appreciated that the book started out with the relatively simple task of getting JBoss installed. However, while the book starts at an introductory level it doesn't stay there. It progresses through more advanced topics such as JMS, JavaMail, JAAS, and Web Services.

The writing is clear and enjoyable throughout. An extended example of a car dealer carries forward throughout the book. This helps the concepts fit together and build upon one another. JBoss at Work is highly informative and, as its subtitle promises, a practical guide. I highly recommend it.

5.0 out of 5 stars Excellent practical guide to JBoss and J2EE, June 21, 2006

This review is from: JBoss at Work: A Practical Guide (Paperback)

J2EE started out as a specification that left the implementation to each container vendor. It's readily apparent that two of the earliest vendors, WebSphere and WebLogic, implemented J2EE in vastly different ways. As a result, early books on J2EE or Enterprise JavaBeans (EJB) frequently either avoided or severely limited the discussion of a specific server because the details were better referenced from server vendors' manuals. JBoss changed that picture. It is an open source Java-based application server which is freely downloadable, plus it is a certified J2EE server.

"JBoss at Work: A Practical Guide", aims to provide practical examples for using JBoss by showing a practical and complete example of a web application running on JBoss. The "JAW Motors" application supports a fictitious automobile dealership. Each chapter progressively adds a new J2EE technology that solves a specific business problem. Viewing cars on a website involves JSP pages and some form of persistence (JDBC or Hibernate). Performing a credit check sends a JMS message and an email response using JavaMail. Purchasing a car requires the transactional support of Stateless Session Beans. Sharing data from the JAW Motors inventory with other dealerships involves setting up Web Services, and so on. The authors' hope is that a coherent business application in action will hopefully give you a clearer idea of how the various layers interact, as opposed to a series of disjointed "Hello World" examples exercising each layer in isolation, and I think their concept worked out very well.

The security portion of the book's example web application makes use of JAAS (Java Authentication & Authorization Service), which enables an application to protect its resources by restricting access to only users with proper credentials and permissions. It is a standard extension in J2SE 1.4, but is not yet widely understood. Thus, one of the appendices is devoted to a tutorial on its use, which I found very helpful.

The authors assume that you're experienced in programming with the Java language and are familiar with Open Source tools such as Ant and XDoclet. They show how to download and install them, and they also provide Ant scripts for compiling and deploying the "JAW Motors" application. If you're new to J2EE, this book serves as a gentle introduction, but don't mistake it for a true J2EE reference manual. I found this book immensely helpful and clear and highly recommend it to anyone who wants to get to work quickly using JBoss as an application server. The table of contents is as follows:

1.0 out of 5 stars A disappointing JBoss book, December 26, 2005

This review is from: JBoss at Work: A Practical Guide (Paperback)

I was looking for a guide for JBoss application server from a beginer's point of view (I have been working with Weblogic for several years but not JBoss) and bought this book since it was rated so high. However, after I finished reading the book, I felt very disappointed since this book talks so little for JBoss! Instead, it puts most of the content on J2EE programming, how to develop 3-tier application, and MVC framework etc. I am not buying this book to learn J2EE techniques!!! What I want to know is how JBoss is managing all its services, how to config different settings, what logging mechanisms are provided (general, JDBC, http, etc.), or how to tune the performance of a JBoss server. Unfortunately, thost topics are either just mentioned slightly (like logging in appendix B), or not there at all.

In summary, if you are a beginner for J2EE and want to start your development with JBoss, this book might be good for you. Don't expect to find more information of JBoss from it! I am a fan of O'Reilly books, but this one is not one of them!
