Dear all: I try to put a file 'log4j.properties' to the roof of the source fold. And any class which use Log4j to output can use the properties. I don't use Apache Struts, but I think copying the log4j.properties to WEB-INF should be OK.
The follow is the content of 'log4j.properties' -------------------------- # All logging output sent to standard out and a file # WARN is default logging level log4j.rootCategory=WARN, STDOUT # Application logging level is DEBUG log4j.logger.com.discursive=ERROR, FILE # Configure the Standard Out Appender log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout log4j.appender.STDOUT.layout.ConversionPattern=%5p (%F:%L) %m%n # Configure a rolling file appender log4j.appender.FILE=org.apache.log4j.RollingFileAppender log4j.appender.FILE.File=output.log log4j.appender.FILE.MaxFileSize=2000KB log4j.appender.FILE.MaxBackupIndex=5 log4j.appender.FILE.layout=org.apache.log4j.PatternLayout log4j.appender.FILE.layout.ConversionPattern=%d %-5p %c - %m%n ---------------------------- ---------------- Kenneth Huang 2006-06-14 Darren Hall wrote: > Excellent! > > My application deploys with no exceptions - however (and now I'm > venturing > into the Log4j side of things) I don't appear to be producing > any log output > at all. > > Dennis, if I could bother you one more time - I'm not sure how > much of a > Log4j expert you are, but here is the log4j.xml file I've created > (modified > from one I found online).

I don't think that log4j creates directories by itself, but it might differ between the various appenders. -- Dennis Lundberg > > Thanks for your help! > > Darren > > (log4j.xml) > > <?xml version="1.0" encoding="UTF-8" ? > > <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" > > > <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"; > > > <appender name="event_file" > class="org.apache.log4j.DailyFileAppender" > > <param name="Threshold" value="DEBUG"/ > > <param name="File" value="log/uwaf-event.log"/ > > <param name="Append" value="true"/ > > <layout class="org.apache.log4j.PatternLayout" > > <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/ > > > </layout > > </appender > > > <appender name="error_file" > class="org.apache.log4j.DailyFileAppender" > > <param name="Threshold" value="INFO"/ > > <param name="File" value="log/uwaf-error.log"/ > > <param name="Append" value="true"/ > > <layout class="org.apache.log4j.PatternLayout" > > <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/ > > > </layout > > </appender > > > <appender name="console" class="org.apache.log4j.ConsoleAppender" > > <param name="Target" value="System.out"/ > > <param name="Threshold" value="INFO"/ > > <layout class="org.apache.log4j.PatternLayout" > > <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p > [%c{1}] > %m%n"/ > > </layout > > </appender > > > <appender name="ASYNC" class="org.apache.log4j.AsyncAppender" > > <appender-ref ref="event_file"/ > > <appender-ref ref="error_file"/ > > </appender > > > <!-- Setup the Root category -- > > <root > > <appender-ref ref="ASYNC"/ > > </root > > > </log4j:configuration > > > > > -----Original Message----- > From: Dennis Lundberg [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 13, 2006 5:04 PM > To: Jakarta Commons Users List > Subject: Re: turning on debugging with commons logging > > Darren Hall wrote: > > Thanks Dennis, > > > > I'm using Struts "out of the box" so I have no logging package > > in place. > > I have no commons-logging.properties file and nothing referring to > > Log4J > or > > anything of the sort. > > > > It seems to me that commons-logging is using the Tomcat default > > logging > > (thus it outputs to 'catalina.log'). > > > > I've gone ahead and downloaded Log4J and included the Log4J.jar > > file in my > > WEB-INF/lib directory when deploying my webapp. I've also created > > a > > commons-logging.properties file (below) that I found as an example > > online. > > > > ######################### > > > > # > > # $Id: commons-logging.properties,v 1.0 2006/06/31 14:35:33Z dhall $ > > # > > > > # > > # This file controls which logging package the Jakarta Commons > > Logging > > package > > # uses.
