I changed to use Log4j.xml from Log4j.properties and also changed to
non-static loggers and with in the static methods followed the link
examples. Now the logging is taking place only for the loggers mentioned in
the static methods, Log log = LogFactory.getLog("pcs"); pcs is the log file
name.
Any idea as to why the non static logger is not working!
thanks,
Sohan
