I'm working on getting logging up on struts with Log4J right now as
well. I'm also new to struts. I am using the following log4j.xml file
(in my WEB-INF/classes) directory and getting a log file successfully.
My 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="appender"
class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="logs/my_log_file.log"/>
<param name="Append" value="true"/>
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p - %d{MM/dd/yyyy
HH:mm:ss.SSS} - [%t] - %m%n"/>
</layout>
</appender>
<root>
<priority value ="debug"/>
<appender-ref ref="appender"/>
</root>
</log4j:configuration>
The "File" param contains a relative path to the log file. My tomcat
server seems to want to put $TOMCAT_HOME in front of that. I'm seeing
my log file appear in the standard tomcat logs directory using the above
XML. I'm using Tomcat 5.5 on windows and log4j 1.2.13 by the way.
One question I wanted to throw out here was how to strip all the tomcat
rubbish from the log file and have it only log messages I write from my
application. I'm getting things like:
DEBUG - 06/14/2006 14:24:45.823 -
[ContainerBackgroundProcessor[StandardEngine[Catalina]]] - Start expire
sessions StandardManager at 1150309485823 sessioncount 1
DEBUG - 06/14/2006 14:24:45.823 -
[ContainerBackgroundProcessor[StandardEngine[Catalina]]] - End expire
sessions StandardManager processingTime 0 expired sessions: 0
and
DEBUG - 06/14/2006 14:23:45.697 - [Thread-1] -
[SetNextRule]{form-validation/formset} Call
org.apache.commons.validator.ValidatorResources.addFormSet(FormSet:
language=null country=null variant=null
Form: LogonForm
Field:
key = userid
property = userid
indexedProperty = null
indexedListProperty = null
depends = required
page = 0
fieldOrder = 0
Vars:
I'm lots of other things that I did not put into the log file myself
(141,300 lines when I empty the log file and just turn on tomcat... some
of which are whitespace). I guess I'm looking for a way to turn off
struts and tomcat logging. Anyone have any thoughts?
Cheers,
R

I tried that. There is no output from log4j to the daily catalina.log files.
However, taking another path, I created a new (and much simpler) log4j.xml
file. Using this new file, I now see the following log file created
'C:\Program Files\Apache Group\Tomcat 5.5\logs\uwaf-debug.log'.
So... progress!
However, the log file contains nothing. None of my info or debug statements
were printed to the file. It's blank. What did I do wrong now?
Any ideas??
Thanks,
Darren

I'm not starting it from the command line any longer. Therefore, I can't

any console output from Tomcat.
Try using a ConsoleAppender and tail -f the log file in the tomcat log
directory.
