1. If there is "logging.properties" file in classpath of your application, it takes precedence over conf/logging.properties There was a case once when some 3-rd party jar file had its own "logging.properties" file that enabled debug logging by default. 2. Log messages are filtered twice: first by logger (whether they are created), second by handler (whether they are printed out by this particular handler). In default configuration 1catalina.org.apache.juli.AsyncFileHandler.level = FINE so you should have seen your messages 3. Beware of typos. Your configuration looks sane. I do not see any obvious errors in it. 4. If nothing else helps, run Tomcat with a debugger https://wiki.apache.org/tomcat/FAQ/Developing#Debugging Best regards, Konstantin Kolinko --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
