Hi Prashant,
I copied the log4j.properites.template to be log4j.preperties, but now all
the information is in stdout rather than stderr.
How should I make it to output to the stderr? I have tried to change
log4j.properties to be
log4j.rootCategory=INFO, stderr
log4j.appender.stderr=org.apache.log4j.ConsoleAppender
log4j.appender.stderr.layout=org.apache.log4j.PatternLayout
log4j.appender.stderr.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p
%c{1}: %m%n
But it still prints to the stdout...
