Martin Lippert from SpringSource announced:
I am happy to announce that we released the first milestone build of the Virgo IDE tooling. For installation instructions, please take a look at the this wiki page:
This is the first milestone build after the code contribution from SpringSource and there aren't that much changes with regards to features or bugs in there compared to the latest dm server tooling releases. But this will change from now on... :-)
Eclipse Virgo Web Server / Kernel is an Enterprise OSGi web server, capable of serving dynamic OSGi web applications via OSGi Web Bundles (WABs). It works with Eclipse Gemini project to provide Java EE 6 capabilities to server-side OSGi applications.
For more in-depth explanation on using OSGi for enterprise applications, I highly recommend OSGi in Action: Creating Modular Applications in Java.
