I have placed a new version of the logging to files patch at http://web1.chicagonet.net/~dmfarb/Apache/Geronimo/index.html
The new patch supports multiple instances per machine, and dated files. If some one wants to commit it to the Apache/Geronimo CVS source base, feel free. I have never built or submitted a patch, so while it works for me your millage may vary. Feedback on improving my processes would be welcome. Thanks David Farb
