 The digester class that tomcat uses to process its config files output an unholy amount of debug information through log4j. I am guessing that you enabled log4j debugging for your webapps and are now seeing the internal logs for Tomcat. You have two options:

• First, you can move log4j into your webapp. Since this will be loaded as part of its own classloader, it should not get the Tomcat internal stuff. If you want a global log4j config for all webapps, you can probably put the jar in shared/lib.
• Second, you can disable debug logging for specific categories(or globally) that are causing you grief. To disable debug logging globablly, in your log4j config file (specified with -Dlof4j.configuration=file:log4j.properties or the log4j.properties file on the classpath), add the line
    log4j.threshold=info
  To disable it for a specific category:
    log4j.logger.org.apache.commons.digester.Digester=info
  If you are using an old version of log4j, the property names change a bit. I think that log4j.logger is changed to log4j.category and log4j.threshold is changed to log4j.priority, but I can't quite remember.
