About the Technology
Modern enterprise applications must be scalable, maintainable, and modular. Unfortunately, by itself Java EE doesn't do modularity very well. The Enterprise OSGi model enforces simple rules to make Java better at modularity. And now, projects such as Apache Aries and Geronimo provide pluggable components that make it easier than ever to use OSGi's mature modularity system in your own enterprise applications.
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.
About the book
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.
- Build modular applications using servlets, JSPs, WARs, and JPA
- Better component reuse and robustness
- Expert tips for Apache Aries
About the reader
The book is written for Java EE developers. No prior experience with OSGi is required.
