How to get the file path of a Log4J log file in Java level?

Assume the log4j.properties file is as below,

log4j.logger.migrationlog = INFO, migration
log4j.appender.migration = org.apache.log4j.RollingFileAppender
log4j.appender.migration.File = C:/work/log/migration.log
log4j.appender.migration.MaxFileSize=20MB
log4j.appender.migration.MaxBackupIndex=1
log4j.appender.migration.layout = org.apache.log4j.PatternLayout
log4j.appender.migration.layout.conversionPattern = %d %-5p %c - %m%n

In such case, your Java code should be as follows,

Logger logger = Logger.getLogger("migrationlog"); //Defining the LoggerFileAppender
appender = (FileAppender)logger.getAppender("migration");
return new File(appender.getFile());

Note that its not migrationlog which was used when making the logger object is used when retrieving the file name, but migration
