Hi Eddie, Have you tried accessing Tomcat directly and not going through Apache? I was having too much trouble using mod_webapp together with Apache and Tomcat due to that form-based authentication didn't work through Apache but it did directly with Tomcat.
Maybe we should all use mod_jk instead. Is anybody running it on Mac OS X BTW?
