Book Description

ISBN-10: 0470843195 | ISBN-13: 978-0470843192 | Publication Date: November 18, 2002 | Edition: 1

A detailed exploration of the basic patterns underlying today's component infrastructures.

The latest addition to this best-selling series opens by providing an "Alexandrian-style" pattern language covering the patterns underlying EJB, COM+ and CCM. It addresses not only the underlying building blocks, but also how they interact and why they are used. The second part of the book provides more detail about how these building blocks are employed in EJB. In the final section the authors fully explore the benefits of building a system based on components.
* Examples demonstrate how the 3 main component infrastructures EJB, CCM and COM+ compare
* Provides a mix of principles and concrete examples with detailed UML diagrams and extensive source code
* Forewords supplied by industry leaders: Clemens Syzperski and Frank Buschmann

Editorial Reviews

From the Back Cover

Component technologies like Enterprise JavaBeans (EJB), COM+ and CORBA Components (CCM) have become mainstream in many application domains. Developers and architects who use this technology in their everyday work need to know more about component infrastructures than the API's of the respective technology. And this is the book they need.

The first part of the book introduces a pattern language that describes how server-side component infrastructures work internally. It does not only adress the basic building blocks and their interactions. It also provides details about the reasons and rationales for this kind of system architecture. For each pattern, the book provides short examples of how it is implemented in EJB, CCM and COM+. These examples thus also serve as a good comparison of those three mainstream component infrastructures.

The second part of the book uses EJB technology to provide even more detailed examples for the patterns, including UML diagrams and extensive source code. Also serving as a comprehensive overview of EJB, it introduces it from the architectural viewpoint and for the developer highlights the consequences of working with that architecture.

Part three offers another approach to the material: a conversation between two people that describes how a concrete application has been built using component technology, focusing on the benefits of this approach.

After reading this book you will:
* understand the principles and patterns of server-side component infrastructures
* be able to design your own proprietary component infrastructures for specific projects
* have learnt about the commonalities and differences between EJB, CCM and COM+
* gain a comprehensive overview of EJB technology
* see how server-side component infrastructures can be used to great benefit in a real application
The "comic" illustrations accompanying the patterns have been created by Stefan Schulz who, when not drawing, works as an independent technology consultant.

Well, the cartoons are nice!

Seriously, the authors go into great detail explaining the nuances of EJB usage. They approach this by using patterns as the key conceptual thread that binds the book together. Now, to some extent, the basic EJB functionality has been stable for several years. So at one level this book won't (and cannot) reveal any more EJB functionality than several other books already published.

But if you regard patterns as crucial organising ideas in their own right, then this book may appeal to you. The patterns are higher levels of usage of EJBs. That perhaps other books have not made so clear, or even mentioned.

Another distinctive feature is a frequent comparison of the EJB components and usages to COM+ counterparts. Every other EJB book I've seen totally ignores COM+, as being in another universe perhaps. In contrast, the authors hope the comparison helps give you more perspective on EJBs. Now, they do also compare EJBs with CORBA. Here, you might also benefit by seeing how EJBs can improve over CORBA implementations. The COM+ may be more pertinent though, as Microsoft seems to be pushing this heavily.

5.0 out of 5 stars What is going on under the hood, January 3, 2006

This review is from: Server Component Patterns: Component Infrastructures Illustrated with EJB (Wiley Software Patterns Series) (Hardcover)

The book presents a pattern language which is applied in implementing the component infrastructure (component and container) on the server side, particularly the EJB (Enterprise JavaBean) model. The patterns are also implemented with little variations by COM+ and CCM (CORBA Component Model).

E.g., how does the component tell container to handle its technical concerns by using ANNOTATION, and how does container intercept component call by using COMPONENT PROXY, manage the resource through LIFECYCLE CALLBACK and PLUGGABLE RESOURCES, achieve scalability and performance by using VIRTUAL INSTANCE, INSTANCE POOL and PASSIVATION, how does the transaction and security related information get passed through INVOCATION CONTEXT, etc.

The basic principles behind these patterns are Separation of Concerns and Functional Variability. The separation concerns between functional (business) and nonfunctional (technical) requirement yields the architecture and collaboration between the component and container; the functional variability yields reusable component building blocks.

No pattern is an island, the book provide a definitive guide on what is composed of server component infrastructure, it is a very valuable resource for both component and container developers, it is a link to chain all the individual patterns, each of which tries to solve one particular software requirement to illustrate how these patterns are working together to form a powerful yet flexible component infrastructure.

Great book about server patterns foundation. This book show up several component patterns in a theoric way, but it converge to pratical way because much of theses patterns are found on web easily. For a programmer or analyst I recommend reading too EJB design patterns that's implementation of theses concepts.
