Well, I learned that the EnglishDictionary.jar bundle it is installed (also
Spellchecker and FrenchDictionary) because I obtained all bundles of the
bundlecontext of felix.
And I extracted the registered services of this bundles with:
ServiceReference[] sb=bc.getBundles()[i].getRegisteredServices();
Printing with:
Log.d("FELIX","registered services: "+sb[j].toString());
I obtain:
02-18 17:40:41.818: DEBUG/FELIX(847): registered services:
[tutorial.example2.service.DictionaryService]
It's a good new. Now...I want instanciate this service ...but I can't
instanciate a "DictionaryService" object :(. Some comment? I continue with
this, slowly but with energy.
Best Regards,
Pablo.
