I develop a Vaadin project in Eclipse that I start through Tomcat 6 which gets started directly by Eclipse. Tomcat prints an enormous amount of log messages though on each start which makes it hard to see the output of my own Application. I have already replaced all log levels in tomcat6/conf/logging.properties by WARNING (e.g. java.util.logging.ConsoleHandler.level = WARNING) but I still get many INFO messages. How can I turn this off or restrict the log messages to WARNING?

An example of the messages
