Hi, I have an app that runs on websphere. log4J works perectly fine on my WSAD environment. But when I deploy the app to WAS, I get that annoying "No appenders could be found for logger .." error.

my log4j jar resides in the WAS_ROOT>AppServer>App.Ear folder and the log4j.xml file sits in WAS_ROOT>AppServer>App.ear>app.war>web-inf>classes along with the application-resources.properties file, log4j.dtd etc.

Does anyone have any idea what I am missing.

Thanks.

MR

Our team faced the same difficulty using log4j on our WAS 4 server (AIX). After searching around I ended up reading the article:

http://www-306.ibm.com/software/webservers/appserv/doc/v40/ae/infocenter/was/rnclassholders.html

We made sure that the log4j-1-2-8.jar file was in the $WAS_HOME/lib/app directory as well as in the module classpaths. I switched the "Module Visibility" of the application server from "Module" to "Server" and now log4j operates properly.

Hope this helps...
