how to list all classes from exported packages of a bundle?
Hi,
I have a no-osgi api that I'm trying to port to osgi. In this api I have
a method that searchs for all classes in classpath that contain one
determinated annotation. So I want to do the same on OSGi.
I've started this challenge by creating one service bundle and I've
create fragments where is the searchable classes. I can find the
properties resources from the fragment nicely... but I can't find a
solution for classes investigation. :-s
I've found one service (org.osgi.service.packageadmin.PackageAdmin) that
gives me the exported packages and fragments (despite the fact it is
deprecated and is not part of OSGi 4.3 anymore) of a bundle. But the
problem is that the ExportedPackages don't gives me any option to list
the classes contained by it.
How could I do that ?
thanks for any help.
regards,
Cristiano

Yes, I should have mentioned that 4.2 does not support this. In 4.2, you can find out the exported packages using PackageAdmin, but the only way to find out the classes is to inspect the actual bundle using getEntryPaths, as Peter has commented on the stackoverflow question. He also notes that you will have to do the Bundle-ClassPath checking yourself, to find out where all the classes can come from.
In short, there (currently) is no fool-proof way that gets you the classes in all cases, without doing a whole lot of work yourself. You might have some chance if you can tightly control the bundles you want to search, e.g. by mandating that only . can be on the bundle classpath.

As Peter Kriens mentions on the referenced web page, it is possible just
a little more difficult since you have to reconstruct the bundle class
path manually.

Hi,
well, this mean that in R4.2 version I can't do what I want or could I have
some alternative?

You could take a look at this Stackoverflow question: http://stackoverflow.com/questions/5856096/osgi-get-list-of-classes-in-package
The question assumes you know what package you're talking about, and you can find the exported packages by using BundleWiring.getProvidedWires(BundleRevision.PACKAGE_NAMESPACE).
