in the log4j.xml file the mango log file is specified as ../logs/mango.log.
On windows instances this creates a 'c:\program files\apache software foundation\logs' directory when tomcat is installed in 'c:\program files\apache software foundation\tomcat 6.0'
Should the log file be specified just as 'logs/mango.log' ?
The problem here is there is a difference in behaviour between Windows and *nix. The latter uses the dir with respect to where the process was started, which is usually <tomcat>/bin, so it would use the existing tomcat logs directory.
