Portconfig error for http listen port

Question

I know that this has been posted alot, I tried to do whatever following all the suggestion in other threads, still no luck.
I installed 10gas (10.1.2) infrastructure 10.1.2 on Solaris 9, and everything was running well. When I tried to change the http listen port from 7777 to 80 following the instruction in the administrator's guide (ch4 Manage port),
log in as root, execute the following command
# cd $ORACLE_HOME/Apache/Apache/bin
# chown root:root .apachectl
# chmod 6750 .apachectl
log in as the installation user (oracle) and execute the following command to configure ...
bash-2.05$ $ORACLE_HOME/jdk/bin/java oracle.sysman.ias.sta.tools.PortConfigCmdLine -oracleHome OARCLE_HOME -oldPort 7777 -newPort 80 -sso -url http://tmsoracle6.tms-hq.com -user root
Error: Invalid newPort value: 80
Changing the HTTP Server Listen port to a value < 1024 on Unix systems requires that the HTTP Server be changed to run as root. As specified in the the Managing Ports chapter of the Oracle Application Server Adminstrator's Guide, this can be done as follows:
cd $ORACLE_HOME/Apache/Apache/bin
chown root .apachectl
chmod 6750 .apachectl
Can anybod help me please? Thanks.

There is only one port for listening, the listen port.
The Port entry is what OHS returns to the browser.
Example:
Webcache runs on port 80, OHS runs on 7778.
Then Listen is set to 7778, and Port is set to 80.
This will ensure that all URLs constructed for the browser are not pointing to port 7778 even though OHS is internally listening on 7778.
