Hey Thomas,
You are registering your Web Provider with Oracle Portal. When Portal attempts to register your provider, it attempts to contact the listener that serves your web portlets. If you have already accessed the sample page: http://host.domain:port/servlet/sample according to the installation instructions, the Portal may not recognize your machine. Make sure the machine where Portal resides can access your Web Provider listener. If you Web Provider server is not part of the DNS, then add an entry in the Portal Server's host file.
Tyr this and good luck
