Gives you a deep understanding of OSGi.
OSGi in Depth presents practical techniques for implementing OSGi, including enterprise services such as management, configuration, event handling, and software component models. You'll learn to custom-tailor the OSGi platform, which is itself modular, and discover how to pick and choose services to create domain-specific frameworks for your business. Also, this book shows how you can use OSGi with existing JEE services, such as JNDI and JTA.
OSGi is a mature framework for developing modular Java applications. Because of its unique architecture, you can modify, add, remove, start, and stop parts of an application without taking down the whole system. You get a lot of benefit by mastering the basics, but OSGi really pays off when you dig in a little deeper.
OSGi in Depth shows Java developers how to develop to the OSGi Service Platform Enterprise specification, an emerging Java-based technology for developing modular enterprise applications.
Written for Java developers who already know the basics, OSGi in Depth picks up where OSGi in Action leaves off.
