is the definitive guide to OSGi, the hottest technology available

for creating modular enterprise Java applications.

What is OSGi? Simply put, OSGi is a standardized technology that allows

developers to create the highly modular Java applications that are required for

enterprise development. OSGi lets you install, start, stop, update, or uninstall

components without taking down your entire system. The interest in OSGibased

applications has exploded since major vendors like Sun, Spring, Oracle,

BEA, and IBM have gotten behind the standard.

OSGi in Action is a comprehensive guide to OSGi with two primary goals.

First, it provides a clear introduction to OSGi concepts with examples that are

relevant both for architects and developers. Then, it explores numerous practical

scenarios and techniques, answering questions like: How much of OSGi do

you actually need? How do you embed OSGi inside other containers? What are

the best practices for moving legacy systems to OSGi?
