Hi Viktor
Can you pleas share the log4j config snippet that I should use. My Java
code's current log4j looks like this. How should I add this new entry that
you mentioned ? Thanks.
log4j.rootLogger=INFO, STDOUT
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p
%c{2}:%L %m%n
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logfile.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{dd-MM-yyyy HH:mm:ss} %-5p
%c{1}:%L - %m%n
