The simplest method of using this Appender * is to add the following line to your log4j.properties file: * * log4j.appender.A1=org.apache.log4j.lf5.LF5Appender * * The log4j.properties file MUST be in you system classpath. If this file * is in your system classpath, a static initializer in the Category class * will load the file during class initialization. The LF5Appender will be * added to the root category of the Category tree. * * Create a log4j.properties file and add this line to it, or add this line * to your existing log4j.properties file. Run the example at the command line * and explore the results! * * @author Brent Sprecher */ // Contributed by ThoughtWorks Inc. public class InitUsingLog4JProperties { //-------------------------------------------------------------------------- // Constants: //-------------------------------------------------------------------------- //-------------------------------------------------------------------------- // Protected Variables: //-------------------------------------------------------------------------- //-------------------------------------------------------------------------- // Private Variables: //-------------------------------------------------------------------------- private static Logger logger = Logger.getLogger(InitUsingLog4JProperties.class); //-------------------------------------------------------------------------- // Constructors: //-------------------------------------------------------------------------- //-------------------------------------------------------------------------- // Public Methods: //-------------------------------------------------------------------------- public static void main(String argv[]) { // Add a bunch of logging statements ... logger.debug("Hello, my name is Homer Simpson."); logger.debug("Hello, my name is Lisa Simpson."); logger.debug("Hello, my name is Marge Simpson."); logger.debug("Hello, my name is Bart Simpson."); logger.debug("Hello, my name is Maggie Simpson."); logger.info("We are the Simpsons!"); logger.info("Mmmmmm ....
