That's the firewall on the server side, depends on what kind of iptables management software is used, you may found iptable rules in /etc/sysconfig/iptables, just add a similar line for port 7080 like that of port 80. then do "service iptables restart", if /etc/sysconfig/iptables is not there, you are on your own to figure it out, Google is your friend.
