Equinox in its purest form has no bundles in it besides the system bundle, and 
IIRC the internal Equinox logger is not exposed.

Pax Logging attempts to provide both OSGi Log Service functionality as well as 
bridging of third-party legacy APIs such as;

 JDK Logging
 Log4J
 Jakarta Commons Logging
 Avalon Logging API
 SLF4J
 KnopflerFish Log
 
Pax Logging consists of 2 bundles. The API bundle must always be present and 
is what all the legacy code will 'bind' into when they lookup a logger the 
respective way. The Service bundle can come and go to allow for upgrade of 
the Log4J driven bakend, without taking down the entire application.
When the Service is not available, the API will revert to System.out (a 
buffering version is under construction).

You find Pax Logging at OPS4J, http://wiki.ops4j.org
