Module 7 Log file not generated for Log4j

Log file not generated in the mentioned path .

Displayed error in console as :
log4j:WARN No appenders could be found for logger (devpinoyLogger).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Error was overcome after putting line as BasicConfigurator.configure(); (internet suggestion)

But still log file is not generated in desired location.
