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
