log4j trouble getting 1.2.6 running

Hi All,

I'm having trouble getting 1.2.6 running. I'm getting the following 
error in the Tomcat log:

Process
Running on RedHat 9 with Sun version 1.4.2_02
1. unzip Barracuda and cd to src directory
2. Ran "ant war" and it failed as couldn't find log4j. I downloaded 
log4j-1.2.8 and put it in the WEB-INF/lib-cvs folder where the build 
script was looking for it.
3. copy Barracuda.war to webapps folder of tomcat-4.1.24
4. Start tomcat and get the error above.

Summary
I can see from the log snippet above that the log4j jar is loading.
I had a look in the source of log4j and there doesn't seem to be a class 
called org.apache.log4j.servlet.InitContextListener

If someone could point me in the right direction that would be much 
appreciated.

Thanks

Stephen
