And how, exactly is Apache supposed to figure this out? ;-)

The simplest way to work around this is to create a minimalist directory
structure on the Apache box with dummy (e.g. zero length) index.jsp files.
Apache can then figure out that it needs to serve 'index.jsp', and send the
request to the Tomcat box to serve the actual page.
