Hey,
What is difference between Eclipse Virgo and Eclipse Gemini?
(I understand what OSGI does in general).

+1  A: 

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.

Honestly, I didn't understand a thing :) It is so theoretical. Easy words and examples are better.

You can see things like this. Gemini isn't a server at all, but Virgo is. The gemini implementation can be used as a part of Virgo, but it also can be used as a part of any other web server. Virgo is a packaging of modules, and gemini is one of these modules.

I got into a discussion with one of our senior developers over this, these definitions from Eclipse are getting ridiculous. They need to do a better job of explaining this.
