How to resolve a bundle fragment

["Jackson, Douglas" <do...@siemens.com>]

Hi!
I am using karaf 4.2.2. I am trying to programmatically resolve a bundle fragment.
I can install the bundle with this:
         Bundle bundle = bundleContext.installBundle(bundlePath);
Then I try to resolve it by doing a refresh on the host bundle:
                    bundle.adapt(FrameworkWiring.class).refreshBundles(Collections.singleton(bundle));
However, the adapt() call returns null.
Do I need to do the adapt() on a particular bundle?

Hi Doug,

a fragment is attached to a host bundle.

So, you just have to install the fragment, it will attach to the host
(and a fragment is not started, only resolved).
You don't have to do a refresh on the host bundle (you might want to do
a refresh on the bundles using the host bundle packages).

So, basically, you don't need the adapt() call.

JB
