Re: tomcat and log4j

Did that, don't see any errors. How exactly does log4j know to
configure itself under tomcat, just by dropping the log4j.properties
file in the right place???

Howdy,
Add -Dlog4j.debug=true to your JAVA_OPTS and check the tomcat logs.  If
log4j runs into errors you'll see them there.

OK, so I changed the file to /tmp/xxx.log
and it still does not show up. Any other
suggestions?

Howdy, You're not going to have file write access to xxx.log from inside a

Ensure the File parameter for your appender in log4j.properties points
to a writeable location.

Thanks for responding. I'm just going by what it says in the log4j
manual:
"The default log4j initialization is particularly useful in
web-server
environments. Under Tomcat 3.x and 4.x, you should place the
|log4j.properties| under the |WEB-INF/classes| directory of your
web-applications. Log4j will find the properties file and initialize
itself. This is easy to do and it works."
I am running jakarta-tomcat-4.1.24 on RH 9 using j2sdk1.4.1_02. I
just
did a jar tvf on my
war file, which shows:

This is what my log4j.properties file looks like:
log4j.rootLogger=DEBUG, roll
log4j.appender.roll=org.apache.log4j.RollingFileAppender log4j.appender.roll.File=xxx.log log4j.appender.roll.MaxFileSize=100KB log4j.appender.roll.MaxBackupIndex=1 log4j.appender.roll.layout=org.apache.log4j.PatternLayout log4j.appender.roll.layout.ConversionPattern=%d [%t] %-5p %F:%L -
%m%n
Everything compiles. I've used log4j in non-web apps. I have log

statements
in my servlet, and I cannot find a log file anywhere. What's up with
that???

Howdy,
It does work if you place logj4.properties in WEB-INF/classes and
log4j.jar in

WEB-INF/lib. If you could please be a bit more explicity when you
say
"This
does not seem to be working" perhaps I could help more.
