Confusion about ThingHandlerFactory [message #1697367]

Although this seems to be a very basic problem, I hope to know the inner mechanism to register a ThingHandlerFactory. As we know each binding should implement its own ThingHandlerFactory and register it as an OSGi service. Take yahooweather binding for instance, YahooWeatherHandlerFactory does not provide any method to register itself as an OSGi service. When turn to BasicThingHandler, it seems that active method might be the right method. However, how to invoke such a method is not shown in BasicThingHandler. So I turn to OSGI-INF folder, in which I found YahooWeatherHandlerFactory.xml. Is it the xml file to be processed by org.eclipse.smarthome.config packages, in order to register it as a service? And how? I hope my question is clear. Smile

Hi Matteo,

These XML are nothing specific to Eclipse SmartHome, but they are the general OSGi Declarative Services approach to handling and injecting services. You can find all details about this here: http://wiki.osgi.org/wiki/Declarative_Services

Kai
