Flexive

Flexive is a Java EE 5 open-source (LGPL) next generation content repository for the development of complex and evolving web applications. It puts strong focus on enterprise-scale content modeling, storage and retrieval, and includes comprehensive JSF support for displaying and manipulating these contents in (web) applications. Including the runtime environment in existing Java EE applications is the one way to write flexive applications, but it is also possible to build new applications and package them into stand-alone Java EE applications.
