Portal Login Failure

Question

When I try to access the Oracle Portal, I get the following error message:
"Proxy log On failed.
Please verify that you have specified correct connectivity information i.e.username, password & connect-string in the Database Access Descriptor
Error-Code:12541
Error TimeStamp:Tue, 03 Apr 2001 22:00:08 GMT
Database Log In Failed
TNS is unable to connect to destination. Invalid TNS address supplied or destination is not listening. This error can also occur because of underlying network transport problems.
Verify that the TNS name in the connectstring entry of the DAD for this URL is valid and the database listener is running."
Now, I've followed through the Troubleshooting section of the Configuration Guide, and it appears that everything works up until I try to access http://host.domain:port/servlet/IsItWorking. According to the documentation:
"Failure to access indicates an issue with the Apache JServ. Most
internal server errors are related to Apache JServs failure to start due to a port
conflict."
So now what do I do???

I am also having the same problem. I am running Oracle 817 and 9iAS 1.0.2.2 on Win2000 (same machine). I am unable to access the Portal Home page. I am able to login to portal_sso. Even though I can start my HTTP Server, my Jserv process keeps aborting. I have checked the wrapper.classpath, and they looks fine. Following is part of the httpd_error_log file in Apache\Apache\logs.
