The error says it all...

java.lang.IllegalArgumentException: Illegal pattern character 'Y'

Try using lowercase y

%d{dd MMM yyyy HH:mm:ss,SSS}

For further info see the Javadoc of org.apache.log4j.PatternLayout and
java.text.SimpleDateFormat

Subject: conversion pattern and date format error


I am setting the date format to use by:

log4j.appender.TRACKING_DEST2.layout=org.apache.log4j.PatternLayout
log4j.appender.DEST.layout.ConversionPattern=%d{dd MMM YYYY HH:mm:ss,SSS}
[%m %n

However I get exceptions.   What am I doing wrong??????

.log4j:ERROR Error occured while converting date.
