Apache Sling is a web framework that uses Java Content Repository to store and manage content. It also uses OSGi (Apache Felix) for dynamic loading.

Description

Apache Sling is a web framework that uses a Java Content Repository , such as Apache Jackrabbit , to store and manage content.

Sling applications use either scripts or Java servlets, selected based on simple name conventions, to process HTTP requests in a RESTful way.

The embedded Apache Felix OSGi framework and console provide a dynamic runtime environment, where code and content bundles can be loaded, unloaded and reconfigured at runtime.

As the first web framework dedicated to JSR-170 Java Content Repositories, Sling makes it very simple to implement simple applications, while providing an enterprise-level framework for more complex applications.
