Logger Initilization

["ITN (Babu Easwaramoorthy)" <Ba...@emiratesbank.com>]

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.Level;
