multiple apps single log4j.xml
Hi Everybody,
I am trying to configure log4j for multiple applications using a single
log4j.xml.I placed log4j.xml in Tomcat's conf directory and placed a
log4j.jar in
Tomcat's lib directory. It is creating the log files, but it is not writing
to it.

First thing, Tomcat's logging mechanism is a whole separate conversation (and also
depends on the Tomcat version you are using). Please read Tomcat's docs about how
to enable Log4j for it's own logging. Alos, No matter what Tomcat version you
use, Log4j *cannot* find its configuration file in Tomcat's "conf" directory. It
"has" to be in the classpath.
Second, for individual logging of your apps, you have not made clear where they
are finding the Log4j config file. Again, for auto-configuration, the config file
*has* to be somewhere in the classpath; either in the global server classpath or
the webapp's classpath, such as WEB-INF/classes.
Try running the server with "java -Dlog4j.debug=true ...". This will tell you
where Log4j is picking up (or not picking up) its config file.

RE: multiple apps single log4j.xml
Posted by ravindra <ra...@btpsoft.com>.
Thanks for the reply Jake,
Let me explain clearly about my configuration. I have placed
log4j.xml file in Tomcat's conf folder and log4j.jar is in lib directory of
Tomcat. And I have another log4j.jar in each of the 3 applications in
webapps.In Tomcat's conf directory servers log4j.properties file is also
there.
The 4 log files of 3 applications are getting generated but, data is
Logging into only root logger, others is empty. And Tomcat's server logging
is not working.

I'm surprised that the log files are being created unless you rigged
Tomcat's
startup scripts to include Tomcat's "conf" directory in the classpath.
Log4j has
no way of knowing where log4j.xml is unless it is in a directory (or root of
a jar
file) that is in the classpath... or you performed manual configuration.
Are you
sure you haven't deployed another copy of log4j.xml along with one of your
jar files?
