Neil Bartlett has written a great article comparing Eclipse extensions and OSGi services. He especially explains the different approaches to services: dynamicy, ServiceTracker, DeclerativeServices and Spring-OSGi.
Two concrete numbers I found interesting:
- ... Peter Kriens (the OSGi Evangelist) indicate that he is in favor of Spring-OSGi becoming part of the OSGi specification in Release 5.
- Therefore a decision was made to build support for OSGi in Spring 2.1.
