Anyone have any ideas on this? This is 100% trivially reproducible: when an app is used with a virtual host parameter, not a single log message relating to that app appears anywhere, and nothing you can change in log4j.xml changes that. This is fragile, broken junk. Logging systems exist for the purpose of logging. Surely there is some way to have both virtual hosts AND logging at the same time? I know that in Apache httpd this is easy to do. Debugging a complicated app without any log output at all is like back to the old days of guessing where the problem is, change something, try it again.
