I guess that my question is a generic OSGi question, but since we are using
Equinox I post the question here.
A common design situation (at least for us) is that several services
implements the same service interface.
Bundle A has a service that implements IMyServiceInterface
Bundle B has also starts a service that implements IMyServiceInterface
We can not have one bundle to start all services of type
IMyServiceInterface, so that is not a slution.
In a prototype we created the IMyServerInterface wasa defined in a separate
bundle. But this gives us MANY
bundles that simply exports a single interface class. The option we had was
to have one big bundle that exposes
all service interfaces.
Which approach is the best? (other options?)
Any advice / comments appreciated
