Here's a common problem that is difficult to figure out. This began happenning early in the Release of Webserver around 1.0 and still happens in 4.0. I suspect the problem exists on all platorms as well. It usually happens after installation:
If you receive the following when trying to load a webserver package.procedure in your web browser (try one of the options):
The request did not specify a valid virtual host
Option 1 - Administration Web:
You should go the the Administration Panel of the webserver and
select (4.0 example / but similar in older versions)
HTTP Listeners ->
Server:listener ->
Network (section):
Add the DNS hostname of your server
Add the IP address of your server (if you don't have DNS)
Now restart the Application Server and things should work!!!
Option 2 - Manually update the Config File:
Stop the Application Server.
Edit the \orant\ows\admin\website40\httpd_SERVERNAME\admin\svlistname.cfg file with your DNS Name (and IP address).
[MultiPort]
ANY 80 NORM www.myserver.com / c:\dir\ NONE
ANY 80 NORM 111.11.11.111 / c:\dir\ NONE
Now restart the Application Server and things should work!!!
NOTE: It's perfectly OK to have the DNS name and the IP address
