Erik published his sample Web Services online today:

I didn't do much to help, but I sure learned a lot by Erik's examples. I didn't realize, for example, that you could produce a WSDL document using the Axis JWS stuff just by passing the page a parameter. That's pretty awesome. THEN there's this cool dynamic test client online which you can give the WSDL to and watch it come up with a form to play with the methods. All around it's a very cool demo of Web Services in action.
