I'm using NB 6 Daily build dated Mar 2, 2007. I created a Web service and then
added an operation to it. The operation takes one parameter and I changed the
default parameter name from "parameter" to "name". The generated method is:

-- cut here --
// Web service operation

   @WebMethod
   public String sayHello(@WebParam(name = "parameter")
                          String parameter) {
       return null;
   } 
-- cut here --

Notice the non-default parameter is not picked up.
