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

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.
Sorry to write a review on our own book but we couldn't leave any information otherwise. The books introduces the basic principles of component-based systems as a Pattern Language. In the first part of the book each of these patterns is described in detail. This also includes a description of its implementation in the three most important Component infrastructures Enterprise JavaBeans, COM+ and the CORBA Component Model. The second part describes in detail Enterprise JavaBeans as an application of the Pattern Language. The last part gives a "story", a conversation that shows how the Pattern Language and EJB influenced the realization of an e-commerce shop system. While there are a lot of books that cover Enterprise Java Beans or other component infrastructures this book gives the basic principles of component infrastructures. The benefit is that it is easy to compare the approaches taken by the infrastructures explained in the book (COM+, EJB and the CORBA Component Model). Learning these principles is also a good foundation to learn one of these systems or to get a deeper understanding of them. Also this Pattern Language can be used as a basis to implement individual and proprietary component infrastructures. For example there is an ongoing effort by Markus Völter to implement a component system for embedded systems based on these patterns.
