The Log4J plugin for Avalon Logging allows for the usage of Apache Log4J log system to be driving your Avalon application. It is a very thin wrapper to Log4J, introducing a single extra method call (non reflected) for the log output methods.
The Log4J subsystem is loaded external to the avalon/logging package, and how this is done for the container you use, can be found in each containers documentation.
The Artifact URL is; artifact://avalon-logging/avalon-log4j-impl#VERSION
where VERSION is the version requested version of the avalon/logging Log4J adapter and NOT the Log4J version.
It is also likely that the container will need to load the Log4J artifact
as well. Again, this is container specific, but the Log4J artifact URL
is; artifact://log4j/log4j#VERSION
where VERSION in this case identifies the Log4J version to be used.
See the Specification for full description of the standard properties.
