Server Component Patterns
Component Infrastructures Illustrated with EJB
Wiley Series in Software Design Patterns
ISBN: 0470843195, Wiley and Sons 2002
The illustrations and pattern summaries are available online.
Component technologies like Enterprise JavaBeans, COM+ and, in the near
future, CORBA Components have become mainstream in many application domains.
Many developers and architects use this technology in their everyday work.
However, there is more to know about component infrastructures than the API's
of the respective technology, and this book shows what.
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 the EJB technology to provide even
more detailed examples for the patterns, including UML diagrams and
extensive source code. The chapter also serves as a comprehensive overview
of EJB, introducing the EJB from the architecture viewpoint, and not
just on the API level.The focus is on highlighting the consequences
of the EJB architecture for the developer.
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,
learn about the commonalities and differences between EJB, CCM and COM+,
gain a comprehensive overview over the EJB technology and
see how server-side component infrastructures can be used to great benefit in a real application
