About This Book

Enterprise OSGi is a set of standards for building modular Java applications which integrate seamlessly with existing Java EE technologies. It extends the OSGi component framework to distributed systems.

Enterprise OSGi in Action is a hands-on guide for developers using OSGi to build enterprise Java applications. Many examples and case studies show you how to build, test, and deploy modular web applications. The book explains how to take advantage of dynamism, distribution, and automatic dependency provisioning, while still integrating with existing Java EE applications.

The book is written for Java EE developers. No prior experience with OSGi is required.
