log4j in shared hosting environment

[cjhowland]

I am trying to use log4j to provide logging in a shared Tomcat hosting environment. I am running Tomcat4.1.29 on a Red Hat Linux/Apache server with the EnsimPro web appliance control panel.

I have uploaded the log4j jar file to /vat/tomcat4/common/lib and placed a log4j.xml file in /var/tomcat4/common/classes and this works to generate a log file for the server.

My log4j.xml looks like this :

<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; ?>
<!DOCTYPE log4j:configuration SYSTEM &quot;log4j.dtd&quot;>

<log4j:configuration xmlns:log4j=&quot;

http://jakarta.apache.org/log4j/&quot;>

<appender name=&quot;appender&quot; class=&quot;org.apache.log4j.RollingFileAppender&quot;>
<param name=&quot;File&quot; value=&quot;/var/tomcat4/logs/log4j.log&quot;/>
<param name=&quot;Append&quot; value=&quot;false&quot;/>
<layout class=&quot;org.apache.log4j.PatternLayout&quot;>
<param name=&quot;ConversionPattern&quot; value=&quot;[%d{HH:mm:ss}] [%-12C] [%p] - %m%n&quot;/>
</layout>
</appender>

<root>
<priority value =&quot;info&quot;/>
<appender-ref ref=&quot;appender&quot;/>
</root>

</log4j:configuration>

What I want to do now is to set up additional configuraton files to allow my customers to generate logs within their own virtual hosting environments and applications. I have tried uploading a log4j.xml file like that shown below to the WEB-INF/classes directory of an application that I know is generating errors in catalina.out, but I get no logs generated.

Does anyone know how to set up log4j in a virtual hosting environment, as I can't find information on how to do this anywhere.

This is my application level log4j.xml :

<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; ?>
<!DOCTYPE log4j:configuration SYSTEM &quot;log4j.dtd&quot;>

<log4j:configuration xmlns:log4j=&quot;

http://jakarta.apache.org/log4j/&quot;>

<appender name=&quot;wasugAppender&quot; class=&quot;org.apache.log4j.RollingFileAppender&quot;>
<param name=&quot;File&quot; value=&quot;/home/virtual/websphereusergroup.org.uk/var/log/log4j.log&quot;/>
<param name=&quot;Append&quot; value=&quot;false&quot;/>
<layout class=&quot;org.apache.log4j.PatternLayout&quot;>
<param name=&quot;ConversionPattern&quot; value=&quot;[%d{HH:mm:ss}] [%-12C] [%p] - %m%n&quot;/>
</layout>
</appender>

<root>
<priority value =&quot;info&quot;/>
<appender-ref ref=&quot;appender&quot;/>
</root>

</log4j:configuration>

Thanks
