The Enterprise Modules Project (Gemini) is all about modular implementations of Java EE technology. It provides the ability for users to consume individual modules as needed, without requiring unnecessary additional runtime pieces.
The modules currently run on the OSGi framework and leverage the OSGi bundle model of packaging and lifecycle activation.
Each of the sub-projects is packaged as a separate and standalone module.
Most of the subproject modules are downloadable and executable independently from the others.
Like everything else at Eclipse, getting started is as easy as downloading and trying it out!
Gemini subprojects have separate releases that can be obtained from their respective subsites.
