I am running Tomcat 5 on XP and after deploying a new war file, which worked, and was the only change I made, the next time I rebooted the machine (after all it is XP) this is what I get:

156593 INFO [main] core.StandardHostDeployer - Processing Context configuration file URL file:C:\Program Files\Apache Software Foundation\Tomcat 5.0\conf\Catalina\localhost\balancer.xml
