I have a java program when I compile it, it compiles fine, without any error or warning. However, when I run it, I get the following warnings.
bash-2.03$ javac CountSessions.java bash-2.03$ java CountSessions Writing data to file... Data written to file !! log4j:WARN No such property [maxFileSize] in org.apache.log4j.DailyRollingFileAppender. log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.DailyRollingFileAppender.
I am wondering, if this warning is critical? and what is it about?
Appreciate your comments,
Thanks and regards.
