OSGi, KnopherFish OSGI, OXSA, Newton, and many others.
This year seems to be a good year to OSGI. Recently IBM and Cisco announced to develop Unified Communications and Collaboration(called UC2) platform based on OSGI. UC2 would not be an open source. So to increase the adoption by developers and industry, these companies would make UC2 freely available.
Anyway, coming back to OSGi which now has many mobile-telecom device vendors on its board. OSGIs start in 1999, it started with JSR-8 ( which was withdrawn). However, quite a few Mobile related JSRs like 232, 239, 246 (Mobile Specs) have come up based on works/concepts from OSGI ( and some JSRs like JSR 277 partially specified features thus became controversial) and some more are coming up JSR291 (Dynamic components) etc
Some of the concepts related to versioning, lifecycle managements, and various other services may find way beyond devices related to Web Services. Off-course, Webservices being stateless, there is already a debate whether 'lifecycle' management makes sense to Webservices or not. However, it all depends on what we makes sense as lifecycle management in the domain.
