another method to achieve this that may be interesting for you is to
use mod_jk to redirect requests coming in on your priv'd port 80
apache daemon to your tomcat processes on an unpriv'd port:

http://tomcat.apache.org/connectors-doc/

I won't go into the whole configuration here - but going this route
may give you more flexibility than using a packetfilter ruleset and
will allow you take advantage of load balancing etc. with mod_jk as
well.  i currently use this setup for a site that serves both static
content from httpd and .jsp pages from tomcat all on the same box.
