log4j does not do anything in servlet!

[developerinlondon]

i am trying to install and use log4j, i am using netbeans to develop. however i can get log4j working fine with a plain java application, but from within a servlet it doesnt seem to do anything, nor does it show any messages, exceptions, errors etc. any ideas how i can find out whats going on? I spent a whole day yesterday looking at the net to see if there is a way but didnt seem to go far.

What does your config file for log4j look like, and where do you put it ?

log4j.properties file (put in the WEB-INF folder) -
# Sample ResourceBundle properties file
log4j.rootLogger=debug, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=c:\\example.log

log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n


In the Servlet I added the following at class level :
static Logger logger = Logger.getLogger(MultiFetcher.class);

and the following in 'init' method :
super.init(config);
PropertyConfigurator.configure("log4j.properties"); // for configuring log4j
logger.debug("please log me!!");
