I think this is fixed with my urn:svn.neurocommons.org:r3437 commit:  I 
get the pretty Swing graphical rendering of the onotologg to appear.

OSGi's bundling rules require that all uses of packages in the core 
JavaSE not in java.* have to be explicitly listed in the Import-package 
statement, so this was a process of running Protege, noting the error, 
adding to MANIFEST.MF, restarting, and then repeating.  I think I got 
better error messages than you as I was connecting to the bundle via 
SLIME, so was able to nose around in the inspector.

The only source of [OSGi documentation of any worth seems to be the 
specification itself][1].  From sparse reading, I would say that things 
are pretty grim for supporting the dynamic abilities of JSS code to use 
other parts of Protege.  As far as I understand things, one needs to 
explicitly declare uses of other bundles at compile time.  There does 
seem to be some provisions for locating services, but I don't think this 
is the way that Protege is coded.

Any sketches of use cases for how you want to extend Protege with this 
thing?
