OSGi is an emerging Java-based technology for developing
modular enterprise applications that can grow and change
easily without stopping them entirely. OSGi in Depth
picks up where OSGi in Action leaves off, covering
important enterprise OSGi services, such as management,
configuration, event handling, and software component
models. Along the way, the reader learns software
engineering best practices that result in systems with
flexibility, extensibility, and maintainability. This
book also describes how a developer can custom-tailor the
OSGi platform, which is in itself modular, by picking and
choosing the appropriate services to create domain-
specific application frameworks.
