configure isqlplus

I have difficulty in configuring isqlplus(9i) on linux I tried the following

1) cd $ORACLE_HOME/Appache/Appache/bin
2) ./apachectl configtest

> OK .... (This worked fine)

3) ./apachectl start

> started .... (httpd seems to have started)

but when i try the following from my client IE web browser

http://192.168.1.1:7777/isqlplus I get page not found

I checked the above port in httpd.conf ...$ORACLE_HOME/Apache/Appache/conf file .. and it has the command
port 77777
but when I try netstat -a port 7777 does not seem to be active , also isqlplus.sql does not seem to be present in the document root of the web server.
I did not configure my client to the proxy setting as mentioned in the configuration document, as I am on a private network and my database server is within . ... OR I need to do it ? ..
have i missed something ? Please help ... I am on ORACLE 9i

I solved this problem after realising that httpd listens on port 3339 for isqlplus by default.

can any one tell me how to change this port .. ie i want to know which files to change.
the file in ..Apache/Apache/conf/httpd.conf has a command port 7778 but it takes default port 3339 , I dont know from which file it takes the same .. can any one help ?
