Hi osgi-over-slf4j developers, I've tested osgi-over-slf4j 1.7.2 with equinox 3.8 and cannot use the SLF4J LogService because Equinox register also a LogService with default ranking 0. SLF4J gets also ranking 0 (default ranking) because no service ranking is explicitly set. Is it OK for you if I introduce ranking = 10 for SLF4J LogService? If want to commit following change: Properties props = new Properties(); *props.put(Constants.SERVICE_DESCRIPTION, "An SLF4J LogService implementation."); props.put(Constants.SERVICE_RANKING, 10);* ServiceFactory factory = new LogServiceFactory(); bundleContext.registerService(LogService.class.getName(), factory, props); to org.slf4j.osgi.logservice.impl.Activator. I also think, that we should made log service ranking configurable ... (via system property for example). With the above change, I can also see OSGi log messages in Beagle ;-) Thats COOL ... Christian
