{quote} Perhaps the simplest way to convert to using Log4j 2 is to replace the log4j 1.x jar file with Log4j 2's log4j-1.2-api.jar. However, to use this successfully applications must meet the following requirements:
# They must not access methods and classes internal to the Log4j 1.x implementation such as Appenders, LoggerRepository or Category's callAppenders method. # They must not programmatically configure Log4j. # They must not configure by calling the classes DOMConfigurator or PropertyConfigurator. {quote}
