I'm trying to setup logback configuration loading in accordance with http://logback.qos.ch/xref/chapter3/MyApp3.html .
When running in OSGi Framework i have the following error:
Error while starting bundle: file:/home/bulat/Desktop/xmppserver/lib/log-0.2.jar: org.osgi.framework.BundleException: Unresolved constraint in bundle ru.rambler.xmpp.server.util.log [13]: package; (package=ch.qos.logback.classic)

Package ch.qos.logback.classic and ch.qos.logback.classic.joran and may be many others should be in Export-Package section of MANIFEST.MF
