ORA-12541: TNS:no listener when using utl_http.request

I am trying to execute the simple command which returns the contents of a URL:

utl_http.request('https://server.domainname.com/test.htm', '', 'file:C:\OracleWallet', 'WalletPwd');

and when I execute it I always get "ORA-12541: TNS:no listener" as an error. This occurs if I use https:// or http://.

Any ideas would be much appreciated! Received on Wed Oct 25 2006 - 11:45:41 CDT
