tomcat7 unable to listen on port 80

Question

I am trying to get tomcat7 to listen on port 80 instead of 8080 on ubuntu 12. I changed the server.xml file to point to port 80 instead of port 8080 - when I restart tomcat, the service does not appear to run at all. No other service is currently binding onto port 80. Any thoughts on troubleshooting this would be appreciated.

<Connector port="80" protocol="HTTP/1.1"
           connectionTimeout="20000"
           URIEncoding="UTF-8"
           redirectPort="443" />

Have you checked, that port 80 is not in use by another (http) server? — Sirko, Feb 04 '14 at 15:30
Is there any chance the URL you are using specifies HTTPS scheme (either with or without port 80 explicitly .. for example, `https://host:80`)? The connector would try to redirect to 443. — David J. Liszewski, Feb 04 '14 at 15:43

I think this is already answered. You can't just set tomcat to listen on 80, you have to adjust iptables (there are other approaches)
