I had unwanted Debugging-Output from org.apache.commons.Digester and org.apache.commons.Digester.sax that made it impossible to continue to work. Everytime i started Tomcat i had to wait 10 minutes for the initialization of a tag library, because of that crap debug output.

This was the solution indeed. Thanks.
