Can't seem to get logging to work in Tomcat 5.5.9
Hi,
I was originally planning to move to Tomcat 6 but backed off for a
number of reasons. Now I have Tomcat 5.5.9 installed an working, except
for logging (and one other problem that I might be able to resolve on my
own if only I could get logging to work).
I have never configured Tomcat to log using log4j (Tomcat 4.x's built-in
was sufficient). Following the instructions on the website
(http://tomcat.apache.org/tomcat-5.5-doc/logging.html), I creating a
log4j.properties file and placed it in common/classes -- the only change
I made on the example on the webpage was to replace a variable with an
absolute path:
log4j.rootLogger=DEBUG, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=/var/apache/jakarta-tomcat-5.5.9/logs/tomcat.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.MaxBackupIndex=10
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
I then put log4j-1.2.7.jar and commons-logging-1.1.jar jarfiles in
common/lib and started Tomcat. The instructions don't say anything about
doing anything else and I've not done very much with log4j other than
use it to enable syslog logging in various applications, but it's not
working.
Any ideas?
Thanks,
Rob

Georg,
Finally kind of solved my problem. First, I went to a fresh install of
5.5.23 and then added the log4j.properties file in
${CATALINA_HOME}/common/classes and the log4j jar file in
${CATALINA_HOME}/common/lib. No go. So, thinking maybe the
documentation was wrong, I moved the properties file to
${CATALINA_HOME}/conf. Again, no go. The I copied it back to
common/classes and therefore unintentionally left a copy in conf. And
suddenly things started working. Of course, log level DEBUG is not
terribly helpful in most cases (too much data) and so I modified the
properties file, switching it to INFO and things broke. Then I
remembered the copy in conf and changed it. What seems to be happening
and makes no logical sense is that so long as I have identical copies of
the log4j.properties file in conf and common/classes, everything works.
I'm sure that somewhere, something is screwed up, but I have no idea
what. Weird!

Hi Rob,
check catalina.out, there should be some message of
log4j complaining if it has been loaded but cannot work.
You may also add -Dlog4.debug to the java command line,
this makes log4j output debug messages on stdout.
If you don't see any output of log4j, then I'd suggest
calling java with -verbose:class, this makes java
print information about every class it loads and from
which source it loaded it. Grep for log4j to see if it
is at all loaded.

I used your config file verbatim and it worked. I can tell you it is not
your config file. Is there any hint at all in the tomcat/logs directory?

Tim,
Right now I'm running Tomcat as root so that it can grab ports 80 and 443 (I
understand there is a work around for that, but I'm not there yet) and so
permissions is not an issue. I also wondered whether the file had to
already exist before it could log to it. So I touched the file and that
made no difference.
Also, I tried removing the tomcat-juli.jar file from $CATALINA_HOME/bin and
that made no difference. Just looking at the startup script, I don't think
JULI conflicts with log4j -- i.e., it doesn't look like if you use one you
can't use the other.

Tim Lucia said the following on 05/25/2007 03:59 PM:
Your configuration file is valid. Does the user Tomcat runs as have write
permission along the output path? You could try using /tmp as a test. If
it is not permissions, then it could be a classpath issue, but your notes
lead me to believe that not to be the case (i.e., you put them where they
should be.
You may (I'm fuzzy on this) have to rename the tomcat-juli.jar file, or
otherwise change the startup script(s) so that it doesn't use the juli
logger.
HTH,
Tim
