Yes, something looks very fishy regarding case sensitivity with the 
log4j support in commons-logging. You might want to file a bug against 
commons-logging and because class naming is inconsistent, and can cause 
user errors (for example, there's a o.a.c.l.impl.Log4jFactory class 
along with a o.a.c.l.impl.Log4JLogger class).

That being said, I've only seen that error occur if the webapp is 
privileged (ie, there's a Context element with a privileged="true" 
attribute). If you don't know what privileged does, and put it there 
because it sounds better, I suggest you remove it (and read the docs) :)
