Thanks for the reply,
but unfortunately, the editor is not the problem.
Realized, that the RollingFileAppender itself is
related to the problem. The FileAppender for instance
works just fine.
However, I stop analyzing the problem. Costs just too
many hours for the "rolling" feature.
Cheers, Holger

Make sure that you have a line return at the end of "logs dir" with
log4j.appender.RFA=org.apache.log4j.RollingFileAppender on it's own line
Something like the following:
<log4j.properties>
# Attach appender stdout to root. Set root level to Level.DEBUG
log4j.rootLogger=DEBUG, stdout, RFA
# The fact that the root level is set to Prority.DEBUG only influences # log
requests made to the root logger. It has no influence on the # *appenders*
attached to root.
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold=DEBUG
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p: [%d] %c{1} - %m%n
# Appender RFA writes to the file "my.log" in tomcat's logs dir
log4j.appender.RFA=org.apache.log4j.RollingFileAppender
log4j.appender.RFA.File=${CATALINA_HOME}/logs/my.log
log4j.appender.RFA.MaxFileSize=200KB
# Keep one backup file
log4j.appender.RFA.MaxBackupIndex=10
# Don't truncate if log file aleady exists.
log4j.appender.RFA.Append=true
# Appender RFA uses the PatternLayout.
log4j.appender.RFA.layout=org.apache.log4j.PatternLayout
log4j.appender.RFA.layout.ConversionPattern=%5p: [%d] %c{1} - %m%n
</log4j.properties>
It looks as if your editor isn't properly representing the file. I'd add an
extra line return between comments and log4j properties (especially those
that wrap at the end of your editor's screen).

Betreff: Problems using log4j on linux/tomcat
Hi,
I've got a problem with log4j on Linux. It seems to be a real issue to track
this problem, since a couple of things might cause this sort of class clash
issue.
However, maybe someone else has found out about the reason for this.
The errors are:
log4j:WARN Failed to set property [maxFileSize] to value "200KB".

The web app contains the following jars:
commons-dbcp.jar
commons-digester.jar
commons-fileupload.jar
commons-lang.jar
commons-pool.jar
commons-resources.jar
commons-services.jar
commons-validator.jar
commons-logging.jar
jakarta-oro.jar
jdbc2_0-stdext.jar
log4j-1.2.7.jar
mm.mysql-2.0.6.jar
struts.jar
The environment is as follows:
- Debian Linux Woody
- Sun JDK 1.4.1_01-b01
- log4j 1.2.7
- Tomcat 4.1.12-3
- Web-app uses struts1.1b2 (which itself uses commons-logging)
Tomcat's lib folders contain those jars:
shared/lib:
lrwxrwxrwx 1 root root 36 Dec 4 14:55
jasper-compiler.jar -> ../../common/lib/jasper-compiler.jar
lrwxrwxrwx 1 root root 35 Dec 4 14:55

Any ideas on how to solve it greatly appreciated!
Thanks in advance for your time,
