Commons Logging Factory for org.mortbay.log Returns a static default log, unless an alternate Log implementation has been set as an attribute keyed by the classname or other name of the log. If the name of the attibute ends with '.*' it is assumed to be a name prefix match. Attributes with string values are treated as references to other attributes. This class needs to be configured in the META-INF/services directory (see build.xml for example) for automatic discovery. Or it can be configured with the system property: -Dorg.apache.commons.logging.LogFactory=org.mortbay.log.Factory
