The XML configuration file for the Log4j logging utility is in the <CCF HOME>/lib directory. If you are using CollabNet Connector Framework version 1.2 or later, it is important that the log4j.xml.rename_me file in your installation be renamed to log4j.xml before you start using the connector. Email notifications are sent to the user configured in the log4j.xml file.
