This project provides a collection of some (hopefully useful) OSGi bundles/components. I’ve recently added the ServiceCollector, an (often) easier to use alternative to the OSGi’s Service Tracker and some bundles for bridging to/from OSGi logging:

• Logging facade for OSGi logging
• SLF4J facade for OSGi logging
• Log4j facade for OSGi logging
• JUL to OSGi logging bridge
• OSGi logging to JUL bridge
