Hi,

I am able to write logger.info message to file but not on the console. Please let me know how to write logger.info messages to both console as well as to the file.

This is how my Log4j.property file look:

log4j.rootLogger=INFO, R

#
#Append to Console
#
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
#
# Print the date in ISO 8601 format
#
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

#
# Append to IUPS ReportsLog.log file
#
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.DatePattern='.'yyyy-MM-dd
log4j.appender.R.File=/Tomcat 5.0/logs/IUPS ReportsLog.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
#
# Print the date in ISO 8601 format
#
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

#
# Application logging options
#
#log4j.logger.org.apache=DEBUG
#log4j.logger.org.apache=INFO
#log4j.logger.org.apache.struts=DEBUG
#log4j.logger.org.apache.struts=INFO

Please let me know.

Thanks in advance,
Anamika

log4j.rootLogger=INFO, R

Change this to:

log4j.rootLogger=INFO, R, A1

Also, the following link might help in configuring the log4j file:

http://logging.apache.org/log4j/docs/api/org/apache/log4j/PropertyConfigurator.html#doConfigure(java.lang.String,%20org.apache.log4j.spi.LoggerRepository)

Note: Could not enclose the above URL in a URL tag, it's giving some errors.
