Enterprise OSGi

Nearly all Java EE Application Servers now use OSGi in their runtimes, greatly improving efficiency, fault tolerance, and security. The new OSGi Enterprise Specification and projects such as Apache Aries and Geronimo, that provide pluggable OSGi components, make it easier than ever to use OSGi's powerful, elegant, and mature modularity system in enterprise applications. Enterprise OSGi in Action is a hands-on guide for developers using OSGi to build the next generation of enterprise Java applications. By presenting relevant examples and case studies, it guides readers through the maze of new standards and projects, arming them with the knowledge to build and deploy enterprise OSGi applications, use automatic dependency provisioning, provide enterprise qualities of service to their business logic, and make use of the Java EE technologies they know and love. ABOUT THE TECHNOLOGY Enterprise OSGi offers a new approach to building modular and dynamic business applications. This modularity lets pieces of the application be reused or extended in a simple, reliable way. Importantly, despite the new concepts, technologies from Enterprise Java can still be used, often with no changes to the original code.
