OSGi: Blueprint vs. Spring DM

Question

I am a little bit confused about Blueprint and Spring DM:

From what I think is true:

• Spring DM is a framework defined by Spring Source
• B

Answer 1

My understanding is that SpringDM is a dead project. Check the GA and release dates. So although it contributed much to the development of the specification in the end it had a bad approach to classloaders. Apache-Aries is a strong blueprint implementation. Note that use of blueprint does not preclude use of spring. I would suggest Karaf as a robust platform that can use either Eclipse Equinox or Apache Felix for the OSGI engine. I like blueprint versus DS if you are developing at the application level where your services may be used by other teams or organizations within your enterprise, or extended by your customers. I think blueprint is also a better fit for traditional enterprise computing environments. But DS or Ipojo may be more appropriate depending on your particular target environment.
