The Default LogFactory Implementation The Logging Package APIs include a default LogFactory implementation class ( org.apache.commons.logging.impl.LogFactoryImpl) that is selected if no other implementation class name can be discovered. Its primary purpose is to create (as necessary) and return Log instances in response to calls to the getInstance() method. The default implementation uses the following rules: At most one Log instance of...
