commons-logging has a habit of being able to find Log4j using classloader tricks, but then not being able to actually use it afterwards because they don't exist in classloaders that are normally visible to each other except via classloader tricks. I think there needs to be two way communication between commons-logging and log4j. The reason I think so is that I remember using Weblogic 8.1 which uses Log4j itself, so it is in the server classpath and having commons-logging in WEB-INF/lib caused similar errors to what you are seeing. I had to put commons-logging in Weblogic's server classpath alongside Log4j, just like Alison did. Seemed to work after that.
Note: I only used commons-logging because we were building a Struts-based webapp. Struts requies commons-logging. I'd *never* use it otherwise, to avoid these ridiculous classloader issues.
