Issue appears to be w/ the wsc file, as noted on the google code site.

Looks like the blog at http://blog.cloudwhiz.com/2009/09/invoking-web-service-in-app-engine.html is no longer available, and I'm running into the same issue. Can someone provide the blog comment that had the solution? Thank you!
