Regarding the WebObjectsLog directive in the WOAdaptor and Apache 2.2, there's a 'feature' where only the initial messages are logged to the file and the subsequent messages for each R/R are not. The problem happens when the log file is created by the parent apache process (usually running as a privileged user) and the subsequent R/R are handled by child processes (usually not privileged.) One fix for this is to change the ownership or permissions on the log file so that the child processes can append to the file!
Due to a longstanding mismatch of case, the more serious error messages which were supposed to be logged to the apache logs were unintentionally squelched. A fix for that and a notice when the child process is unable to append to the log file are on their way to the Wonder repository. ;-)
