Osgi

OSGi

The OSGi framework (OSGi being an acronym for "Open Services Gateway initiative") is a module system and service platform for the Java programming language that implements a complete and dynamic component model, something that as of 2012 does not exist in standalone Java/VM environments. Applications or components (coming in the form of bundles for deployment) can be remotely installed, started, stopped, updated, and uninstalled without requiring a reboot; management of Java packages/classes is specified in great detail. Application life cycle management (start, stop, install, etc.) is done via APIs that allow for remote downloading of management policies. The service registry allows bundles to detect the addition of new services, or the removal of services, and adapt accordingly.
