OSGi (Open Services Gateway Initiative)
- Dynamic Module System for Java
- Provides a mechanism to break an application into modules for which:
- dependencies are explicitly defined and must be provided
- the services provided by the module are explicitely defined
- versions of dependencies and services are understood
- Applications run inside of an OSGi container which performs all of the dependency checking
- Three interoperable containers: Equinox, Apache Felix, Knopflerfish
- Dynamic
- Applications can be installed, uninstalled, started, and stopped on-the-fly
- An OSGi bundle is simply a standard Java jar with the addition of a Manifest which specifies the services that the module provides as well as the modules dependencies (among other things)
Spring DM (Dynamic Modules)
- Allows for the creation of OSGi bundles through the use of Spring xml
- Provides a way to support OSGi without your code needing to be aware of OSGi (or Spring)
- OSGi services can be injected into application-wired Spring-beans
- Application services can be deployed as OSGi services
- Especially useful if you intend to take advantage of Spring for other purposes within your application
- PAX Construct provides scripts which handle some of the setup/configuration of an OSGi project
- Maven plugins for creating bundle artifacts
