Hi Yes I totally agree OSGi bundles can be a library hell. That is why there is an alternative FAB which I blogged about here http://www.davsclaus.com/2012/08/osgi-deployment-made-easy-with-fab.html We have users on Fuse ESB that uses Hibernate with FAB deployments and dont have the OSGi hell. An alternative some people have done as well, is to create one giant uber JAR / bundle with all the Hibernate JARs and its dependencies. And possible enable dynamic osgi imports and whatnot. But yeah its a hell to manage... > > First. > Why do we have to repackage every library is not in the form of > bundle? > It would be easier, more manageable, to wrap missing libraries (not > in the form of a bundle) around a container that describes its contents. > This way something like, say, apache.commons does not need to be > unpacked and packed with a new manifiest.
