NoClassDefFoundError in Osgi w/ Felix, ant

After a lot of work migrating our code to another & fixing all the manifests and the bundles, when I try to run the applet on the server I get many errors like this one:

All the bundles are getting resolved properly, and even when I tried to get some code out of the external jar into our code, it still threw me that error, I know that's a problem in Felix that I need to fix, but I don't know where can I start, all the bundles starting in their proper time...

I'm building the app with ant/Felix.

Maybe it's a problem with the activator? Thanks for all the help, love to hear some opinions...

Your bundle is using the class org.jitsi.service.configuration.ConfigurationService but it doesn't import the package. Make sure that org.jitsi.service.configuration is listed in the Import-Package header in your bundle's manifest.
