Fuse ESB Enterprise uses the OPS4j Pax Logging system. Pax Logging is an open source OSGi logging service that extends the standard OSGi logging service to make it more appropriate for use in enterprise applications. It uses Apache Log4j as the back-end logging service. Pax Logging has its own API, but it also supports the following APIs:
Apache Log4j
Apache Commons Logging
SLF4J
Java Util Logging
