Problem viewing web service in wsnavigator

I have a portal project with a working portal service and component (for testing the portal service). I've followed the documentation Creating" target="_blank">http://help.sap.com/saphelp_erp2005/helpdata/en/43/037446dcc721ace10000000a1553f6/frameset.htm">Creating a Web Service from a Portal Service to create a web service and deploy it. The problem I'm having is that I can't find any indication that my web service exists on the portal. It doesn't appear in wsnavigator and I can't access the WSDL via URL. Any ideas on what I might be missing?
