Logger Initilization

[ITN \(Babu Easwaramoorthy\)]

Hi   I do want to attach an  Appender, layouts to a Logger without using log4j.prop file . I tried the below     I initialized the Logger (the name of the logger is the log file name) in the constructor by setting DailyRollingFileAppender  to the Logger as below.   Next time in the JVM when I try to create the same Logger (in the Log method) with the file name I am not getting the Logger instance to which I attached the DailyRollingFileAppender. I am getting different instance and getting appender could not be found message.     Can any one help to understand this     Below is the source code.   Thanks in advance, Babu   import org.apache.log4j.Logger; import org.apache.log4j.Level; import org.apache.log4j.Layout; import org.apache.log4j.PatternLayout; import org.apache.log4j.DailyRollingFileAppender;     public class EBEAILogger {       private EBEAILogger()     {}       public static final int OFF = 0;     public static final int FATAL=1;     public static final int ERROR=2;     public static final int WARN=3;     public static final int INFO=4;     public static final int DEBUG = 5;     public static final int ALL =6;                             static final String datePattern = "yyyy-MM-dd.'log'";             static final String logPattern = "%d %-2p [%c{3}] - %m - [%F:%M:%L] %n";                 public EBEAILogger(String fileName)             {                         try                         {                                     Layout layout = new PatternLayout(logPattern);                                     DailyRollingFileAppender appender = new DailyRollingFileAppender(layout, fileName, datePattern);                                     private static Logger logger =  Logger.getLogger(fileName);                                                                        logger.addAppender(appender);                                                             }catch(Exception e)        {                                     e.printStackTrace();                                                 }                                   }                                     public static void log(String fileName, String message,int logLevel)             {                         Logger logger = Logger.getLogger(fileName);                           switch (logLevel)                         {                                     case DEBUG:                                                             logger.debug(message);                                                             break;                                     case WARN :                                                             logger.warn(message);                                                             break;                                     case INFO :                                                             logger.info(message);                                                             break;                                     case ERROR:                                                             logger.error(message);                                                             break;                                     case FATAL:                                                             logger.fatal(message);                                                             break;                           }             } }     DISCLAIMER: This Electronic Mail and any attached information are confidential and may also be privileged.
