JBoss at Work: A Practical Guide

Book Description

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.

JBoss at Work: A Practical Guide

Great book. It is as the subtitle implies: a practical guide. It was easy to work through the book and the sample code and get a quick yet detailed overview of JBoss and Java web technology. Unlike some huge books, I did not get lost in the complexities. Any technology like this is complex enough as it is. I like to start with an overview, and this book is exactly that: a great introduction and overview. Even so, it's practical enough to put the knowledge to work right away. Hence it's "JBoss at Work."

Encompassing.......2007-10-11

Aimed at the beginning J2EE developer, this book does a great job of encompassing several exciting technologies and showing how they can all work together (JBoss, Ant, XDoclet, Hibernate, etc.) to achieve the end goal of deploying a robust ear file. XDoclet and ant pair to automate several of the tedious tasks (read deployment descriptor generation) no developer wants to be bogged down with. I am a huge fan of how it introduces all the necessary technologies involved w/o diving into the mundane detail of each and every one. If more depth is required, citations are always provided to other great O'Reilly titles. This book stays true to its title w/o going off on tangents due to other author's personal bias. All decisions are objectively defended (like their decision to illustrate Hibernate as their ORM of choice) and options are always provided. Very practical and a great starting point. Overall, two thumbs up.

Great Developer book for starters to JBOSS.......2007-08-15

Its a great book if you have just started your development with JBOSS 4. It is easy to read from a developer/deployment perspective and also delves into how to automate the deployment descriptors and deploy into JBOSS. Covers most of the common J2ee/Web applications using hibernate and Ant. Probably needs upgrading to JBOSS 5 but is great if your current development is in JBOSS 4.

Great learning tool.......2007-06-27

I am most of the way through this book and so far, it's been extremely helpful and informative. It breaks all the steps down one by one and takes you from a simple Hello-World type app, to a more complicated enterprise application. A great read all-around.

Good ground up walkthru.......2007-03-23

I found JBoss at Work to be a great guide that takes you through the basic JBoss setup and configuration. Its perfect for someone who wants to get an overview of the process and understanding of how JBoss works, but doesnt want to take the time to become an expert. It serves well as a guide on understanding J2EE general development and also highlights the JBoss specifics when appropriate.
The only downside for me was the tedious review of the J2EE XML configs. I would have preferred to see just the XDoclet code and not the additional XML that it generates. Use that time to focus on WHAT config files are necessary opposed to what actually gets generated and goes into them. Its beyond the scope of the book to go into all the XML syntax in the configs so its not worthwhile to try and make the reader understand this. Again, a little extra is not so bad, but it does fill a good portion of the book with something I believe could have been left out or supplemented with a better review of what each config file does and when to use them.

Book Description

Like many other incipient technologies, Web services are still surrounded by a tremendous level of noise. This noise results from the always dangerous combination of wishful thinking on the part of research and industry and of a lack of clear understanding of how Web services came to be. On the one hand, multiple contradictory interpretations are created by the many attempts to realign existing technology and strategies with Web services. On the other hand, the emphasis on what could be done with Web services in the future often makes us lose track of what can be really done with Web services today and in the short term. These factors make it extremely difficult to get a coherent picture of what Web services are, what they contribute, and where they will be applied.

Alonso and his co-authors deliberately take a step back. Based on their academic and industrial experience with middleware and enterprise application integration systems, they describe the fundamental concepts behind the notion of Web services and present them as the natural evolution of conventional middleware, necessary to meet the challenges of the Web and of B2B application integration.

Rather than providing a reference guide or a "how to write your first Web service" kind of book, they discuss the main objectives of Web services, the challenges that must be faced to achieve them, and the opportunities that this novel technology provides. Established, as well as recently proposed, standards and techniques (e.g., WSDL, UDDI, SOAP, WS-Coordination, WS-Transactions, and BPEL), are then examined in the context of this discussion in order to emphasize their scope, benefits, and shortcomings. Thus, the book is ideally suited both for professionals considering the development of application integration solutions and for research and students interesting in understanding and contributing to the evolution of enterprise application technologies.

Comprehensive text on Web Services.......2007-09-17

First part of the book while describing Distributed Systems, Middleware and EAI lays strong foundation for Web Services. Second part of the book provides an extensive reporting about Web Services Architecture, related standards, service composition and BPEL. Though at the outset this book looks like serving academic purpose but it also provides the great insight of the subject to the programming community.

This book is must have which draws detailed conceptual and architectural views on Distributed Systems, EAI and Web Services.

Clear explanations, good fundamentals.......2007-03-16

I am using this book for a graduate level class about Web Services. I like the books approach on giving you enough background about middle-ware evolution that makes it easier to understand what Web Services are trying to accomplish. Given that the actual technology (implementation details) change so much in this area the books approach makes a lot of sense. I also found explanations to be concise and clear.

Advice: if you are looking for a hands-on how-to book about XML this is not the book to pick up. Otherwise, if you are looking for a good fundamentals book that will help you paint a big picture of Web Services this book is great!

Great Book on Distributed Systems.......2005-04-05

This book is a little more expensive than most of the flashy Web Services books these days but it is well worth the money. Set in small font and not wasting pages on chapters like "History of XML and SOAP" this book is dense in content on the architecture of distributed systems, including Web Services. We get to learn about the issues of distributed transactions and the differences between conversations, coordination and orchestration. The text is precise but nevertheless easy to follow. One of the best books I have seen on Web Services architecture.

You can find a sample chapter on the author's site:

Comprehensive .......2005-01-12

If you want comprehensive high level overview of today's enterprise software landscape, this is a must-read.

One of the best books which answers the question , Why Web Services?? Unique perspective on middlewares in general.

Do not expect any code examples or details of any particular middleware.

Excellent book on web services.......2003-11-24

A very nice introductory book on Web services, much different from all the others on this topic.
Excellent overview of the problematics of service oriented architectures on the Web and of their relationships with their EAI counterparts (corba,rpc,..).

As a student of SOA & adaptive business networks (composite channels), this book fills a void in my knowledge base. The book is worth buying just for the chapter on Capability Cases, a pre-use case methodology.

Unable to clear up the 'fuzziness'.......2006-02-14

You'd think that a book attempting to explain semantic technologies would make an extra effort to be as clear and practical as possible so as not to make the subject even more confusing.

I think this book would have been better if it was written by only one author. Part of the book was written clearly and was obviously directed toward a reader who was not familiar with semantic (and other, related) technologies. This author clearly laid out various ways that semantic technology is (and can be) used. Information provided about current products and companies using this technology was also very informative.

Other parts of the book, however, were written as if the reader is just as familiar with the technology as the author. It seems as though one of the authors was more concerned about how they sounded (in writing) to themselves (and possibly their colleagues) than they were in attempting to give practical knowledge about the subject to an uninformed reader. It's difficult enough to understand the subject of semantic technologies without having to fight through densely-written sentences and unnecessarily vague buzz words (like "follow-on query"??).

I was interested in learning exactly HOW this technology enables interoperability "with little or no human intervention" but found no difinitive, practical explanation of how this is achieved. Yes, I understand that ontologies and inference engines are involved, but how do they work together to remove the human part of the middleware equation? How is the "mapping" involved in semantic technologies different from the "mapping" that is involed in today's EAI solutions? I thought that this is the most exiting and unique selling proposition of this technology but I finished this book unsatisfied with how this was explained. Perhaps this selling point is more of a vision than a reality?

An ambitious but yet unfulfilled vision.......2005-12-13

How is the meaning in natural language related to the meaning in computational machines? The answer to this question is of course of immense importance to the information age, and the lack of an answer has resulted in vast financial commitments from businesses that depend heavily on information technology. The sharing of information between machines has been hampered by the lack of common understanding between these machines, since each one of them has its own way of formatting or conceptualizing the data. Even though some of these machines should definitely be characterized as `intelligent', there is of yet no machine that can communicate or share information with any arbitrarily selected machine in a manner that is independent of the nature of this information. There are some machines that are capable of interacting with many other machines in this manner, but at some point when confronted with a particular machine, they are unable to converse meaningfully without some amount of human intervention. This intervention must take place because the machines do not understanding the meaning of each other's data. They cannot conceptualize it without the assistance of a human, who must then give the appropriate (semantic) translation between the data patterns of the respective machines.

The authors of this book approach these questions in terms of what they have called `semantic interoperability.' This notion is supposed to settle the difficulties of meaning and definition that occur not only in natural language but also in communications between software applications. The context of words in digital systems is dependent on both domain cues and local cues, just as is the case for natural languages, they authors say. Data context for example influences the interpretation of data, and therefore it's meaning may change if viewed from another context or perspective. `Data semantics' then is the meaning of data, and will change as the context changes. Therefore, a successful data processing system will need to make the data semantics explicit. The authors discuss various approaches to the understanding of semantics, such as pattern analysis, schema mappings, and abductive logic. Of all the approaches discussed, the authors seem to favor the one based on abductive logic, referring to it as the least developed approach but one that shows the greatest promise in going beyond rule-based digital systems. However, the authors are incorrect in stating that this approach is not very well developed, as there are a few highly resilient systems, used primarily in bioinformatics and telecommunications, that make heavy use of abductive reasoning.

The conflicts that can occur between data on different machines motivate the authors to consider various approaches in dealing with these conflicts that does not involve customized code. After reviewing the specific types of conflicts that can occur, such as those due to data type, labeling, naming, and domain, the authors review some of the different `semantic solution patterns', for dealing with them. These include the `machine learning pattern' that is based on statistical analysis and reasoning patterns from artificial intelligence and is used to discover semantics within instance data; the `third-party reference pattern' which uses a thesaurus or ontology having a shared meaning across sources and targets; the `model-based mapping pattern' which uses well-defined metadata about context instead of mappings between data structures; and the `inference pattern' that requires a formalism to describe the semantic relationships in the system.

The authors obviously believe that these approaches are not entirely satisfactory, or they would not have written this book. Most of the book therefore is devoted to their solutions for solving semantic conflicts. Central to their approach is the role of metadata, which is viewed by the authors as forming a hierarchy with six layers: instance data (essentially "raw data"), syntactic metadata (needed to process data), structural metadata (which gives form and structure to units of data), referent metadata (to provide linkages between different data models), domain metadata (forms a "conceptual domain ontology" to provide a reference point on which all metadata can be understood), and rules (which constrain the semantics of metadata specifications).

One might call the authors approach a version of ontological engineering, the latter term being used currently to describe efforts to make data understandable in different contexts. In this regard, the authors consider four different types of ontology, namely interface (models essentially the API), process (applying to time-dependent processes), information (specification of a collection of concepts for a given scope), and policy (specification of rules of usage). Of particular interest in their discussion is that of the transformation of ontologies, which allows the moving of data from one model to another.

The approach that is advocated in this book is that of semantic interoperability, which the authors view as a `multimodal' solution since it can apply to different modes of operation and is not tied to a particular technology. A successful semantic architecture however is not a "plug-in" to be incorporated easily into standard middleware. Instead, it is an engine that is dynamic and adaptive, and responds real-time to changes by generating its own instruction sets. At first glance this engine would seem be one that is enormously complex, but the authors break it down into its modes of operation, in order to clarify just how it would function. Crucial to their conception of semantic interoperability is that it allows the discovery and utilization of new information without the intervention of a human. If such a capability can indeed be realized, it would definitely be a major advance and would justify the expense of its operation. The authors discuss in fair detail just how semantic interoperability would work in a business enterprise, at least schematically. To alleviate any skepticism on part of the reader of the reality of their ideas, they devote a large amount of space in the book to (nonproprietary and proprietary) case studies of implementation of semantic interoperability. Although these studies to not encapsulate all of the author's ideas, they do serve to convince the reader that these ideas should be taken seriously.

This book will not disappoint. For serious semantic web practitioners ( novice or pro ), this book is an invaluable asset. The text provides a very detailed and expansive commentary on the current 'state-of-art' in Semantic Technology, rich in case studies the authors hit their mark squarely.

Hardly Worth the Money.......2003-10-21

After I decided to shell out 65 bucks for a book of only 280 pages I was disappointed that the page count included filler chapters such as "Introduction to the Internet" and "Introduction to Object Technology". The remainder is primarily an overview of different distributed technologies, e.g. COM, CORBA etc.
If you are interested in a good overview over EAI, I recommend to get for Fred Cummins' and / or Chris Britton's books instead (about the same price for both of them).

Great content, translation needs work.......2003-10-02

This book is a nice overview at a high level and not tied to a particular implementation. However, some of the sentence translations are difficult to read. For example, "a second possibility is to decompose an application into a set of elements that are connected by this relation." Overall, very good book.
