Hot to get access to an OSGi service in a bundle Activator (e4)? [message #1208008]

Hey guys,

I want to save and restore a value from an OSGi service via eclipse
preferences (the last opened object of type O). I thought of doing this
in the bundle Activator of my application bundle. Is it possible to get
access to the OSGi service respectively to start the service in order to
retrieve the value? If not, what is the best way to store and retrieve
values via the eclipse Preferences API during startup and shutdown of
the application?

Thanks in advance for any help
Marina

in an e4 app i would use the lifecycle hook @PreSave which is called
when the application is shutdown.
