Hello,
I have a bundle containing some DS components and I would like to have
different behaviour whether Preference Service bundle (and other
compedium services) is available or not.
First thing I did was to declare the import of org.osgi.service.prefs
package as optional in the manifest and then set the component's service
reference cardinality to ReferenceCardinality.OPTIONAL.
But it quickly turns out that this is not enough... I got a
NoClassDefFoundError as soon as I started the container.
Well, if I understood right what happened, I need to have at least a
bundle providing the API classes installed. right ?
So, what would be the best approach when the implementation is also
packed and delivered with the API in one bundle, as it is the case of
Felix ones. or in cases where it is not, as is the case with Equinox?
should I pack those required packages with my own bundle also? or use
the new api binary bundles provided by osgi alliance?
any tip is welcome.
many thanks,
Cristiano
