apache proxy listening on multiple ports

I'm using apache to proxy my tomcat instance, and I would like apache to listen on both ports 80 and 8080. I have the given configuration. But when I try to start up I get the following error:

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down

Listen 8080
NameVirtualHost *:8080

Listen 80
NameVirtualHost *:80

<VirtualHost *:8080 *:80>

   <Proxy *>
     AddDefaultCharset Off
     Order deny,allow
     Allow from all
   </Proxy>

   ProxyPass / ajp://localhost:8009/
   ProxyPassReverse / ajp://localhost:8009/

</VirtualHost>

Is there a way to get apache to basically proxy all requests on 80 and 8080?

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down

This error message means that there is something already listening on the port. On linux, the following command can give you the data as to what is listening.

netstat -lnptu
