Server Component Patterns

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 BuschmannEin Band aus der 'Wiley Software Patterns' Bestseller-Reihe.

"Server Component Patterns" erläutert Komponenten-Infrastrukturen.

Dabei geht der Band über die reine API-Perspektive hinaus und vermittelt dem Leser ein tieferes Verständnis dieser Architekturen und ihrer Auswirkungen für die Entwicklung komponentenbasierter Software auf Pattern-Basis.

Teil 1 des Buches diskutiert aber nicht nur die zugrundeliegenden Bausteine, sondern auch, wie diese miteinander interagieren und warum man sie einsetzt.

Teil 2 vermittelt dann in allen Einzelheiten wie diese Bausteine in EJB verwendet werden.

Teil 3 untersucht, welche Vorteile ein System bietet, das auf der Basis von Komponenten entwickelt wurde.

Anhand von Beispielen demonstrieren die Autoren anschaulich, wie die drei wichtigsten Komponenten-Infrastrukturen - EJB, CCM und COM+ - im Vergleich miteinander abschneiden.

Mit einer Mischung aus Grundsätzen und konkreten Beispielen mit detaillierten UML-Diagrammen und umfangreichem Quellcode.

Glossary.

Index. Markus Völter, Alexander Schmid and Eberhard Wolff work as IT consultants, trainers and office managers for MATHEMA AG in Germany. They share a professional interest in new software development technologies, distributed systems and have experience of component-based development and enterprise architecture obtained during many development projects of all kinds and size. The three of them are regular speakers at conferences. Markus Völter is an active member of the international pattern community. 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.
