---------------------------------------
Thanks for the prompt reply. As you pointed out, there was a mismatch between
the rolling file appender name and its corresponding reference, which I fixed.
I have also made additivity=false as I don't want to use root logger but the
logger which I configured. I am now using the Logger "logger" to log to file.
I am still not able to see class names in the log. Instead of the class name I
see a "?", and I don't really understand why.
On a side note, how is it that the logger is able to know the caller class
name? Is it through Reflection, or are some Thread shenanigans used?
