SEAM 3 and Weld (JSR299)

Hello ranchers,

I attended a seminar few days ago and the speaker briefly mentioned SEAM3 and Weld (JSR299) ... saying it may be the future of java development. I don't know much or haven't use the current SEAM (v2) framework so I can't comment. And I haven't looked at JSR299 in detail yet but from what I heard, it does sound promising.

Does anyone heard or know about this?

Correct me if I'm wrong, the idea I got was to build an interface like object injecting/triggering modules which are themselves the little libraries that make up well-known frameworks (eg Spring, Struts, EJB, JSF etc).
