HTTP Listener Problem

Question

i write this post also Apex forum but i couldnt get any answer for weeks. I guess this is a hard question.
Re: i can't reach the remote host
as i posted above url, i cannot reach the remote host via typing host address in browser. I can connect in sqlplus, plsql, there is no browser. But i cannot reach that remote host from browser.
I did:
installed the apex 3.1.1 successfully and i validate it.
i also run the apex_epg_config file.
set the http port with dbms_xdb.sethttpport functionso, browser said to me "cannot find server". I am posting result of "lsnrctl status", so it might guide you.

The command completed successfully
i think that a line that includes http listening is missing. Because i have another machine, i can connect it from sqlplus,plsql,browser. And i typed "lsnrctl status" in its terminal the http listener line is seeming as this :
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=XXXHOST.tcelldomain)(PORT=8082))(Presentation=HTTP)(Session=RAW))
As i said, above line is not seeming first machine.
What do you think about it?
thanks for responses.

In general, APEX can be accessed either by using the Listener/DBMS_XDB or the Apache HTTP server access.
It appears that you want to use the Listener/DBMS_XDB access. In which case, the theory is:
User requests connection to host:port
Listener on 'host' listens on port, as directed by DBMS_XDB
Listener passes request to DBMS_XDB (using shared server technique) which passes it to DBMS_EPGTo get listener to monitor the port, you need to use DBMS_XDB to register the http (or ftp) port to the listener. That is done using the dbms_xdb.gethttpport and verified using dbms_xed.gethttpport
Refer to the DBMS_XDB docs for details. http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_xdb.htm#sthref8053
Check the output of
select dbms_xdb.gethttpport() from dual;
