Introducing OSGi:
modularity, lifecycle,
and services
The
OSG
i framework defines a dynamic module system for Java. It gives you
better control over the structure of your code, the ability to dynamically manage
your code's lifecycle, and a loosely coupled approach for code collaboration.
Even better, it's fully documented in a very elaborate specification. Unfortu-
nately, the specification was written for people who are going to implement it
rather than use it. In the first part of this topic, we'll remedy this situation by
effectively creating a user-oriented companion guide to the
OSG
i framework
specification. We'll delve into its details by breaking it into three layers: module,
lifecycle, and services. We'll explain what you need to understand from the spec-
ification to effectively use
OSG
i technology.
