Oracle 10g express and 11g express DB homepage is not showing up - oracle

Question

I just installed Oracle for the first time and the last step of the installer is to ask if I want to check the home page. I checked it, the browser opened a local website, but this website does not exists. So I am simply stuck here.
I tried 10g first, I uninstalled it and tried 11g. I always get a non-running webpage. I tried it because I saw in some answers that 10g was not supported by Windows 7 32 bits and that 11g was.
Each time, I checked if all the Oracle services were up and they are. I also checked if the port 8080 was used and it is not. Also, disabling the Windows firewall gives nothing.
I know nothing about Oracle so please give me some links if you are talking about Oracle specific things.
If you don't know the problem with the website, could you tell me which service is supposed to start the website and were is its logfile so that I could see the error?
Thanks
In a side note, in the project install guide, I am supposed to run "sqlplus system#xe" after Oracle is installed. When I do it, I have to enter the password and then I get "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor". Each questions about that error was about "it worked fine for a week and now no more" which is clearly not my situation, so this is not my question, just a side note.

Answer 1

One of my teammate found the answer. The problem was in the installation and here is what worked:
Warning for Windows7 only:
Oracle 10g installation on windows 7
32-bit completes without error but it is incomplete. In order to fix
the problem, before installing Oracle, shut down your PC, unplug your
network cable, boot your PC and install Oracle (not a joke), and
reconnect only after the installation of Oracle 10g.
That is weird, but it worked
NOTE----This method doesn't worked with 11g express R2 . (ofcourse i am talking of windows 7)

Answer 2

Try this:
1) First, make sure it's running. It sounds like it is from the error message you got in step 2, but double check that the Services (OracleServiceXE and OracleXETNSListener) are both started. Those are the only two services you need, and it does sound like the OracleServiceXE may not be running.
2) Make sure it's not running on a non-8080 port. From a command prompt, run netstat -an and see if anything is listening on port 8080. I've seen it get installed on alternate ports (including 9080) in the past.
3) If there's something listening on port 8080, try http://localhost:8080/ in your browser. If there's something on 9080, try that.

Answer 3

I too faced the same issue and fixed by following the below steps.
go to your Oracle XE 10g console using sqlplus. Replace mypassword with that your SYS user password (as specified during the installation process). Note that the number 2, 3, 4 at the left side is generated by the sqlplus tools prompt (you don't need to type them in).
[sourcecode lang="sql"]
C:\> sqlplus sys/mypassword#xe as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production on Thu Jun 18 17:53:47 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to:
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production
SQL> begin
2 dbms_xdb.sethttpport('8484');
3 end;
4 /
[/sourcecode]
Oracle XE should reply:
[sourcecode lang="sql"]
PL/SQL procedure successfully completed.
[/sourcecode]
After that check to ensure that the configuration has been changed properly:
[sourcecode lang="sql"]
SQL> select dbms_xdb.gethttpport as "HTTP-Port is " from dual;
[/sourcecode]
You should get a message like this:
[sourcecode lang="sql"]
HTTP-Port is
------------
8484
[/sourcecode]
Exit from sqlplus by typing "exit" at the prompt.
Now restart the PC and check.e same issue.
