Logging im Tomcat

[Olli]

Hallo,

meine Applikation erzeugt unerwartet viel logging:

[DEBUG] ManagerBase - Registering Catalina:type=Manager,path=/myappl,host=localhost
[DEBUG] ManagerBase - Force random number initialization starting
[DEBUG] ManagerBase - Getting message digest component for algorithm MD5
[DEBUG] ManagerBase - Completed getting message digest component
[DEBUG] ManagerBase - getDigest() 0
[DEBUG] ManagerBase - Force random number initialization completed
[DEBUG] ManagerBase - Start: Loading persisted sessions
[DEBUG] ManagerBase - Loading persisted sessions from SESSIONS.ser
[DEBUG] ManagerBase - Creating custom object input stream for class loader
[DEBUG] ManagerBase - Loading 0 persisted sessions
[DEBUG] ManagerBase - Finish: Loading persisted sessions
[DEBUG] Auswertung] - Sending application start events
[DEBUG] Auswertung] - Starting filters
[INFO] PropertyMessageResources - I

wo kann ich das abstellen?
web.xml und server.xml führen nicht zum Ergebis

Danke
