Are you looking for a GlassFish-specific answer, or are you looking
for something that will work with all Java EE 6 products?
With GlassFish you might be able to get some of this information
from OSGi, but I'm not sure we've decided how "stable" the bundle
information is.
At the Java EE level we could require the information used by
java.lang.Package, if that would help.
