ContextLoader No log appenders found in Tomcat

[Joe Harry]

Guys,

I would like to enable logging in my Spring application and Tomcat. But when I tried to bring up the server which is Tomcat 6, I get the following message:

Nov 22, 2009 4:14:17 PM org.apache.catalina.core.AprLifecycleListener init

Of interest is the warning message. How to get rid of that?

[Joe Harry]

Just managed to get rid of this. Added the Log4JConfigListener and added it as the first listener in my web.xml and this solved my issue. Something like below in my web.xml...

    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>    
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<listener>
		<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
	</listener>

The order of the listeners seems to be important.
