Hey,
What is difference between Eclipse Virgo and Eclipse Gemini?
(I understand what OSGI does in general).
From the Virgo proposal :
Gemini
Virgo provides a runtime enterprise application model on top of Equinox, with integrated application and provisioning support. The Gemini project at Eclipse.org provides implementations of enterprise capabilities that can be exploited by such applications. The Virgo kernel provides just the foundational capabilities and depends solely on the Gemini Blueprint Service project. The Virgo server distribution pre-integrates the Gemini Web Container and Blueprint Service projects. Additional capabilities provided by Gemini projects can easily be added to the Virgo Server simply by deploying the appropriate bundle provided by those projects.
