Subject RE: Logging Problem on Upgrade to Tomcat 6
Date Wed, 22 Aug 2007 18:58:00 GMT
What is confusing me is that I never had to catch the exception and
log it from within my application in Tomcat 4, 5 or 5.5 - it just appeared
in the web app log automatically.

Is there no way to configure Log4J/Tomcat 6 to do the same thing without
having to do as you suggest?

it will only log to the webapp.log if your application catches the
exception, then issues a log.error("msg",exception) (tomcat will do the same
assuming it was correctly configured)

if you provide a sample war, I can validate it for you
