java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory with dropbox
example Component
I've created an EventHandler service similar to the dropbox example [1]
Is this example still current for the sling trunk build?
I have the same boilerplate initialization for the Component as the dropbox example:
@Component(immediate=true)
@Service(value=EventHandler.class)
@Property(name=EventConstants.EVENT_TOPIC, value=SlingConstants.TOPIC_RESOURCE_ADDED)
public class WebDavFolderWatchIngestService implements EventHandler {
/** Default logger. */
protected final Logger logger = LoggerFactory.getLogger(this.getClass());
at bundle load time I get a java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
02.02.2015 22:00:24.074 *ERROR* [FelixFrameworkWiring] org.apache.felix.scr [com.nim.ct.dam.ingest.service.WebDavFolderWatchIngestService(141)] Error during instantiation of the implementation object (java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory)

My runtime has:
g! lb | grep slf
11|Active | 1|log4j-over-slf4j (1.7.10)
13|Active | 1|jcl-over-slf4j (1.7.10)
15|Active | 1|slf4j-api (1.7.10)
I'm building my own runtime launchpad using the launchpad module with some additional dependencies & versions added to the list.xml.
Any hints on next steps appreciated.

Disregard, resolved.

Another oddity I noticed is that if I try to examine my components from
the sling web console components tab, selecting any of them gives a 404
rather than any actual information. This implies there is something broken
in the structure of the bundle an possibly not related to the actual log
errors I¹m getting.
