configuration attributes on the instantiated LogFactory instance. Once an implementation class name is selected, the corresponding class is loaded from the current Thread context class loader (if there is one), or from the class loader that loaded the LogFactory class itself otherwise. This allows a copy of commons-logging.jar to be shared in a multiple class loader environment (such as a servlet container), but still allow each web application to provide its own LogFactory implementation, if it so desires....
