Where can I find a bundle implementing the org.osgi.service.log.LoggerFactory service?

I am trying to get a minimal OSGI bundle running using the OSGI logging facade (org.osgi.service.log-1.4.0).

When I try retrieving an implementation of the LoggerFactory class I just get null. I'm assuming this is because the org.osgi.service.log -bundle does not contain any implementation of its own service.

I understand what's missing in my application is a logging implementation, but I'm struggling with finding a bundle that is able to supply me with this.

Where can I find a simple bundle that provides my environment with an implementation of the org.osgi.service.log service (version 1.4.0)?

Information about my environment:

  • Karaf 4.2.7
  • Java 11
  • org.osgi.service.log-1.4.0

My code can be wiewed here.

Solution

  • Apach Karaf 4.2.x is based on OSGi R6. The log service is part of R7 which should be available in Karaf 4.3.x.
