I've reproduced the issue and run it with a debugger. The above scenario misses step "create 404.jsp". Actually it is more severe. After reload the Mapper$ContextVersion object does not contain information on wrappers (the *wrappers fields in it contain empty lists). Thus after reload *any* page in the examples webapp is inaccessible and results in error 404. (In case of a custom error page "servletContext.getRequestDispatcher(errorPage.getLocation());" call in StandardHostValve.custom() returns null ). Unfortunately, it is [x] Broken - do not release Best regards, Konstantin Kolinko --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
