Repeated log messages log4j

[srsrikkanth rajendran]

I am using log4j in my struts application.
The messages get repeated muliple to=imes.
I am not sure whats the problem. Kindly advise.

I instantiate my logger as
logger = Logger.getLogger("WSO");

my properties file is as follows:
# Set root logger level to DEBUG and its only appender to CONSOLE1.
log4j.rootCategory=DEBUG, CONSOLE1,ROLLING1

# CONSOLE1
log4j.appender.CONSOLE1=org.apache.log4j.ConsoleAppender

# CONSOLE1 uses TTCC (Time, Thread Category, Context) Layout
# Levels used to be called Categories in older versions of log4j.
log4j.appender.CONSOLE1.layout=org.apache.log4j.TTCCLayout

log4j.appender.ROLLING1=org.apache.log4j.RollingFileAppender
log4j.appender.ROLLING1.File=wso.log
log4j.appender.ROLLING1.MaxFileSize=1000KB
log4j.appender.ROLLING1.MaxBackupIndex=3
log4j.appender.ROLLING1.layout=org.apache.log4j.TTCCLayout
