What version of Log4j are you using now? You spoke about 1.2.9 in the past
tense and 1.2.11 only just came out. I'm guessing you are using
1.3alpha? Seems like a classloader issue where two different versions of
Log4j are being seen by two different classloaders. Check that you only
have one version of Log4j in your classpath.
