Hi, I noticed when a Filter (probably pre-loaded Servlets too) throws RuntimeException it's logged, but not displayed, and then it makes an WebApp entirely unavailable (503 error). While not display an error summarizing exception name, message, optionally stack trace in stdout? Normally (Tomcat running as a deamon) stdout is ignored, but if such info would be displayed it would speed up error tracing in development environment. Looks like it could be easily fixed by a small addition between lines 3000-3100 in StandardContext, at least for filters. Something like displaying: Starting Tomcat... [...] Exception while initializing Filter for context "hostname": Exception name: RuntimeException Exception msg: error reading xml configuration from file "/WEB-INF/filter-config.xml" WebApp "hostname" unavailable because of errors in Listeners initializers. I'd say stack trace isn't necessary here because it's availabe in logs, and writing in would probably scroll exception name and message off-screen (not all environments have scrolling on command line) which would defeat its purpose on making this info available instantly. Greetings, deacon Marcus p.s. I'm using Tomcat 4.0 b6
