Try this: <param name="Expression" value="TIMESTAMP > '2007/08/10 14:48:00' && TIMESTAMP < '2007/08/10 14:48:40' && LOGGER ~= 'com.creditex'"/>
Note you need to use spaces around operators, operands AND parens. The timestamp format displayed above is the only one supported. Don't forget to add single-ticks around it. Scott Deboy -----Original Message----- From: WALLIS, Simon, GBM [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 15, 2007 8:58 AM To: 'Log4J Users List' Subject: ExpressionFilter and TIMESPAN Hi again, I'm wondering if it is possible to use the ExpressionFilter to only log events occurring within a certain time span each day. For example, I don't want to log events in my application between the hours of 01:00 and 03:00 (due to scheduled environment outage where tons of errors are spewed forth). It seems that the TIMESPAN filter field in ExpressionFilter is a long which represents a specific date. So I could then log all events occurring after, say, "2007/01/01 12:00". But can I use this to only log events relative to a certain time each day? If it can only be a hard date, then I don't see much point of the filter, unless you knew that you didn't want to log information for a given day at some point in the future (an unlikely scenario). Here's my appender below. I've got it to only log events from com.creditex, but I want to restrict it further that that it doesn't log events between 01:00 and 03:00 each day. <appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p [%t] %c (%F:%L) - %m%n"/> </layout> <filter class="org.apache.log4j.filter.ExpressionFilter"> <param name="Expression" value="(LOGGER ~= com.creditex)" /> <param name="AcceptOnMatch" value="true"/> <param name="ConvertInFixToPostFix" value="true"/> </filter> <filter class="org.apache.log4j.filter.DenyAllFilter"/> </appender> One more thing: why is TIMESPAN a long instead of a date string in the format of, say, "yyyy/MM/dd hh:mm:ss". Is there a quick way to determine the long value of a date I have in mind? Cheers.

It turns out the problem was that I didn't have jakarta-oro-2.0.8.jar in my classpath. I'm not sure if I was supposed to know about this requirement, but I didn't notice it until I stepped through the log4j code in my debugger and saw it was getting a class not found exception trying to throw a MalformedPatternException. I've got it working now so thanks for your help!

Thanks for the feedback. I've tried but haven't been able to reproduce the problem. The log that I'm getting looks like: log4j: Threshold ="". log4j: Class name: [org.apache.log4j.net.SMTPAppender] log4j: Setting property [SMTPHost] to [blah]. log4j: Setting property [from] to [EMAIL PROTECTED] ]. log4j: Setting property [to] to [EMAIL PROTECTED] ]. log4j: Setting property [subject] to [my subject]. log4j: Setting property [bufferSize] to [50]. log4j: Parsing layout of class: "org.apache.log4j.PatternLayout" log4j: Setting property [conversionPattern] to [%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{1}:%L - %m%n]. log4j: Setting property [expression] to [msg ~= blah]. log4j: Setting property [acceptOnMatch] to [true]. log4j: Setting property [convertInFixToPostFix] to [true]. log4j: Adding filter of type [class org.apache.log4j.filter.ExpressionFilter] to appender named [SMTPAppender]. log4j: Adding filter of type [class org.apache.log4j.filter.DenyAllFilter] to appender named [SMTPAppender]. log4j: Adding appender named [SMTPAppender] to category [root]. log4j: Level value for root is [DEBUG]. log4j: root level set to DEBUG Disconnected from the target VM, address: '127.0.0.1:56913', transport: 'socket' The next major event that follows "Setting property [convertInFixToPostFix]" that ends your log should be the call to propSetter.activate() in DOMConfigurator.parseFilters. The propSetter.activate() call should in turn call ExpressionFilter.activateOptions(). If that had succeeded, then you should have seen the "Adding filter of type ...ExpressionFilter" message from the line following the propSetter.activateCall(). If you can set a breakpoint on the propSetter.activate call and then step-into, hopefully you can get an indication of what is going wrong. I made up a test case that parses an configuration file with your snippet of configuration code.
