Oracle HTTP server - Page canot be displayed

[renu richard]

I am not able to visit the server page by using URL 'http://localhost:8000'. It gives error 'Page can not be displayed'. I tried with port No 7777 and 7778 also but got the same error.
In 'httpd.conf' file in location ORACLE_HOME\Apache\Apache\conf also the port is mentioned as 7778.
I got this server with database installed I am using it for the first time.
While we start the server we are getting following error:

[Wed Dec 17 13:14:32 2008] [error] forcing termination of child #0 (handle 792)

Can anybody help us in getting this resolved, please.

I don't have a lot of experience with OAS... but here is a link to the default ports and their associated components.

I would also make sure the wdbsvr file is where OAS thinks it is and that it is a valid configuration file.
