One of my developers found this very interesting paper on the problems using commons-logging (like Axis 1.x does) while trying to upgrade ColdFusion's log4j implementation from 1.1 to 1.2.
http://www.qos.ch/logging/classloader.jsp We might want to consider converting Axis 1.x to use the SLF4J: http://www.slf4j.org/ We encountered several of the problems mentioned in the paper specifically because Axis uses commons-logging instead of log4j directly. -- Tom Jordahl Adobe ColdFusion Team
