OSGi (Open Service Gateway Initiative) is a Java framework for developing and deploying modular software programs and libraries. OSGi has two parts. The first part is a specification for modular components called bundles, which are commonly referred to as plug-ins. The specification defines an infrastructure for a bundle's life cycle and determines how bundles will interact.
