There is a nice SpringSource blog about their plans for building OSGi applications. Actually, it’s more an advertisment for their tool called bundlor which basically has the same purpose as bnd but is implemented in a different way.
There is one point in the blog the I don’t like at all. It’s yet again I hear the myth about automatically generating OSGi bundles from 3rd party libraries and how successful it is used in the SpringSource bundle repository. Folks, it might work for one 3rd party library but it will never work in an automated way for all 3rd party libraries. There are just too many issues around OSGi-fying 3rd party libs which need to be addressed carefully. If the library deals with class loading you might be out of luck no matter how great your generated manifests look like. You need to modify your source code and/or patch the 3rd party library to make it work correctly. Even better, sometimes there are multiple ways to convert a 3rd party library into an OSGi bundle. A stubborn one-to-one conversion process cannot incorporate that. It may depend on your requirements and preferences.
