Tuscany and Web Services newbie question

[Dan Becker]

I've been looking at the Tuscany sample helloworld-ws-service. Could 
someone answer how the WSDL helloworld.wsdl was generated?

Manually? If so, what's the best way to generate it from the files in 
src/main/java/helloworld? I've tried various wsdlgen commands on the 
classes in target/classes, and wsdlgen always seems to have trouble 
finding the service end point (A web service endpoint could not be 
found()). I've also tried adding some @WebService and @WebMethod 
annotations, but with no insight.
