Hm... I had the same problem once, and I figured it was because Tapestry doesn't use the log level configured for the "org.apache.tapestry5" category, but the level you define for your components.
As it is said on http://tapestry.apache.org/tapestry5/guide/logging.html : When a component's logger is configured at the DEBUG level, you will also see added output when the class is first accessed identifying how Tapestry is modifying the bytecode of the class. That is something I find quite annoying and don't see much use in, by the way. Anyway, for me it worked using a log4j filter, as described in an earlier conversation on this list, see http://www.nabble.com/T5%3A-How-to-configure-T5-not-to-display-unwanted-log-td16024408.html I don't think it makes a difference if you use logger or category in your log4j.xml. Actually, I think category has been renamed to logger at some point, so you might actually want to stick with logger. Hth, Lutz On Tue, Aug 12, 2008 at 12:24 AM, Filip S.
