Re: How to configure to use tomcat and struts to use log4j?
Looks like Struts has a dependency on Commons Logging which is using Log4j under the hood. The commons logging jar is being loaded from a higher level classloader (common/lib or server/lib) and can't access classes only provided by a lower classloader (your webapp). Maybe try having the commons logging jar in your WEB-INF/lib. Where is the struts jar you're using? WEB-INF/lib or higher?

Howdy, Looks like Struts has a dependency on Commons Logging which is using Log4j under the hood. The commons logging jar is being loaded from a higher level classloader (common/lib or server/lib) and can't access classes only provided by a lower classloader (your webapp). Maybe try having the commons logging jar in your WEB-INF/lib. Not a bad suggestion. Remember, you should always be able to have your webapp work if you all your jars are in WEB-INF/lib and no jars are elsewhere. - Root Cause - java.lang.NoClassDefFoundError: org/apache/log4j/Layout Note the difference between NoClassDefFoundError and ClassNotFoundException. The classloader found a log4j jar, but it does not contain the Layout class. List the contents of your WEB-INF/lib.
