org.settings4j.helper.web.Log4jConfigurationLoader

public class Log4jConfigurationLoader
extends Object

With this Implementation you can define a Key in your web.xml (init-parameter "settings4jLog4jConfigurationKey") with that you can configure your Path to your log4j.xml.

Each WebApplication in you Servlet Container can have its own key. And so you can configure for each webApplication a separated log4j.xml.

See Example Log4jConfigurationLoaderListener.
