All right, so we assume, there are no log4j things lying around in your Tomcat apart from your webapp. Also please check, that the running Tomcat process has no -Dlog4j.configuration in its commandline.

It could be, that you have a servlet initialization, that configures log4j via its API, but let's assume this is not the case.

Then even without the context-param, the log4j.properties in your WEB-INF/classes should be found as the default configuration. Maybe the context-param is an indicator, that there is explicit log4j initialization code in your webapp and you are not using autoconfiguration.

In both cases we assume it really picks up the WEB-INF/classes/log4j.properties.

So if a file gets created but nothing gets logged into it, we should have a look at the contents of the log4j.properties file. You should post it.

Also: which messages would you expect there?

I deploy a war file with the following content.
WEB-INF:

one        exists.
        lib:
           contains the log4j-1.2.9.jar not in any other directory

my web.xml contains

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:log4j.properties</param-value>
  </context-param>

I hope that's the information you ask for!
thanks

How do you deploy the log4j Jar? Which place? Several places?

Where do you keep your log4j configuration file? One file, several ones?

Which mechanism did you choose to publish the files to log4j?

The questions concerning "several" always mean: are those things only in your webapp, or also added to the container installation?

Depending on the answers, it's relatively easy (after understanding tomcat class loaders and log4j default configuration mechanisms) to explain, which config gets evaluated and why.

Hi

I have a problem with tomcat 5.5.20. My application uses log4j 1.2.9 and I
am sure that all my implementation is correct because I uses JUnit and the
logging works fine with it. However, Tomcat loads my log4j.properties so
the
configuration of the web.xml should be right. I know that because the log file is created but it contains no entries.
Moreover my log4j.properties is used in other projects without tomcat and
works file. Is there a special configuration of the tomcat?

Thanks
marc
