Problems with web services generated code.

Hi All,

In IntelliJ 10.0.3

I use the menu option "new web service" and this generates a class file and adds to sun-jaxws.xml - this is fine - it's working.

Now if I try to write a Java client for this web service I get IllegalArgumentException TestWebService is not an interface

Here's my client code:

public class WebServiceTest {

    public static void main(String[] args) throws Exception {

        URL url = new URL("http://localhost/services/TestWebService?wsdl");

        //1st argument service URI, refer to wsdl document above
        //2nd argument is service name, refer to wsdl document above
        QName qname = new QName("http://ws.mydomain.com/", "TestWebServiceService");

        Service service = Service.create(url, qname);

        TestWebService test = service.getPort(TestWebService.class); // fails here


        System.out.println(test.sayHelloWorldFrom("TESTING...."));

    }

}

How should I implement this? Should I have an interface and a class?  Is there a good example? Best practice?
