I am now trying to deploy my Rails application to Torquebox 2.0.3 on Ubuntu Server 11.04. Now it's correctly deployed , I could visit the application on port 8080. but I could not configure the server to listen to port 80.

I tried to set the port to listen in $TORQUEBOX_HOME/jboss/standalone/configuration/standalone.xml :

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">


    <socket-binding name="http" port="80"/>


After that when I start Torquebox by calling torquebox run, and I get the following error:

15:47:07,804 ERROR [org.apache.coyote.http11.Http11Protocol] (MSC service thread 1-1) Error initializing endpoint: Permission denied /
    at [jbossweb-7.0.13.Final.jar:]

But I find no process is holding port 80:

$ sudo lsof -i :80
$ sudo netstat -tulpn | grep :80

How could I solve this problem and configure jboss server to listen to port 80?

Lower numbered ports - lower than 1024 tend to be restricted to root users - the best/simplest way to get around this is to forward port 80 to 8080 internally at iptables or at the network's firewall, rather than at the application level.
