Hi,

i would like to load a rap plug-in (which are osgi bundles) dynamically by another rap plug-in. The latter plug-in (a rap application) is running and should be able to load an additional plug-in based on a user input. Afterwards i want to access some classes of the loaded plug-in. The plug-in to load is located somewhere in the filesystem.

The goal is to get the same handling as adding the plug-in as dependency in the manifest, just doing this while runtime.

I deal with rap just since a few weeks. I searched for this issue but didn't find a satisfaying answer. Read something about a BundleContext in the Activator. Could someone explaine a bit?

Would be kind if you post some short example code.

Kind regards,
Patrick

Hi Patrick,

The BundleContext is given to you once your bundle is started and if it
provides an Activator (see first page of the Manifest Editor). You're
free to hold on the BundleContext to reuse it later for installing bundles.
You should be able to use BundleContext#installBundle to dynamically add
bundles to the runtime. Maybe you even need the PackageAdmin to force
the bundle to be resolved but please ask on the Equinox group if you
still encounter problems.

Regards,
Ben
