The OSGi technology allows an application to be divided into multiple modules, each of which can be deployed as a bundle that has its own version, life cycle, and dependencies. The SpringSource Application Platform is a comprehensive platform that integrates the Equinox OSGi container with different supporting technologies to take full advantage of the modularity and versioning of OSGi.

Pro SpringSource dm Server™ is ideal for learning how to develop and deploy modular applications to run on the SpringSource Application Platform.
