So TC 7.0 released last month with the Servlet 3.0 spec. 3.0 has some great new features for deploying servlets programmatically and with annotations. This really seems like something Virgo could leverage in it's feature set... being able to deploy an OSGI bundle with Servlet 3.0 annotations would be incredibly powerful. I could deploy and undeploy servlets through the bundles without needing a WAR. Is TC 7 on the roadmap yet?
Wow, jokes on me... I haven't looked at 3.0.0.M05 yet. Sorry about that.
As for deploying servlets in bundles, I think it'd require an HTTP Service be a part of the Virgo natively, but that's what TC is for, so I'd still deploy a WAR with my annotated servlets and that'd be all I'd need. So I suppose I answered my own question
