No appenders could be found for logger

["Kalita, Bitap Raj (RAPID APPLICATION DEVT)" <Bi...@morganstanley.com>]

Hi 
I am using log4j in my application deployed in Webshere 5.1.
I am getting the following error on systemerr file 
 
log4j:WARN No appenders could be found for logger (APP).
log4j:WARN Please initialize the log4j system properly.
 
I have configured the log4j by calling
PropertyConfigurator.configure(Properties file.)
The properties file is created by reading the log4j configuration from
database.
Following is the log4j configuration used.
 
 
log4j.rootLogger= DEBUG
log4j.loggerFactory = log.OFXLoggerFactory
 
log4j.appender.A1=org.apache.log4j.RollingFileAppender
log4j.appender.A1.File = F:\LogFiles\OFX\OfxApp.log
log4j.appender.A1.MaxFileSize =5000KB
log4j.appender.A1.MaxBackupIndex=4
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
 
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.loggerFactory=com.msdw.ofx.logging.OFXLoggerFactory
 
log4j.logger.OFX = INFO, A1
log4j.logger.APP = DEBUG, A1
 
I can see the logger name APP and OFX and they behave as configured,but
the error l
og4j:WARN No appenders could be found for logger (APP).
log4j:WARN Please initialize the log4j system properly is shown anyway.
 
I have checked in code also that the appender is attached to the logger.
Thanks,
Bitap Raj
