using webservices transparent

[Martin Thoma]

Hello,

I am trying to integrate an external web service(represented by WSDL) in a SCA 
component within the Tuscany platform (Version 1.3.1). The web services is 
specified as reference in the component composite, as well as annotated in 
implementation code(see below). The example that I implemented was similar to 
the xml-bigbank example in the tuscany 1.3.1 version. With the examples (see 
code below), I got different results. But I want to use a transplant solution 
provided by the tuscany framework, where I don't have to use generated stub 
code(e.g. from axis2 wsdl2java) in the implementation(client) code.    

As a first step  I developed a external test webservice operated on axis2 
server(outside the tuscany framework).

To use this web service in the tuscany platform, I declared this interface, 
which represents external web service(inside tuscany framework):

 
        @Remotable
        public interface TestService{
                Result foo(Request r);
        }



with Result and Request as normal POJO classes.

The binding in client.composite:
        <reference name="testService">
                <binding.ws 
wsdlElement="http://targetnamespace/#wsdl.port(TestService/TestServiceSoap)" />
        </reference>

the corresponding wsdl
        <?xml version="1.0" encoding="utf-8"?>
                <wsdl:definitions targetNamespace="http://targetnamespace/";
                        xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";>
                <wsdl:import namespace="http://targetnamespace/";
                        location="http://localhost/testservice?wsdl"; />
                </wsdl:definitions>

                
the TestClient (implementation of remotable interface):

        @Reference 
        protected TestService testService;
        ...
        Request r = new Request();
        Result rs = testService.foo(r);

        
and everything works fine (no axis,axis2, etc. stuff in client code) ;-)


Now I tried to integrate a foreign external webservice 

(URI: http://www.webservicex.net/WeatherForecast.asmx?wsdl):

The interface:
        @Remotable
        public interface WeatherService  {
        GetWeatherByPlaceNameResult GetWeatherByPlaceName(String placeName) 
throws java.rmi.RemoteException;
        }

and again with GetWeatherByPlaceNameResult as POJO class.

The binding 
      <reference name="weather">
            <binding.ws 
wsdlElement="http://www.webservicex.net#wsdl.port(WeatherForecast/WeatherForecastSoap)"
 />
            </reference>

the corresponding wsdl
        <?xml version="1.0" encoding="utf-8"?>

                <wsdl:definitions targetNamespace="http://www.webservicex.net";
                        xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";>
                <wsdl:import namespace="http://www.webservicex.net";
                        
location="http://www.webservicex.net/WeatherForecast.asmx?wsdl"; />
                </wsdl:definitions>
                
and the TestClient:

        @Reference
        protected WeatherService weather;
        ...
        GetWeatherByPlaceNameResult result = weather.GetWeatherByPlaceName("New 
York");
        System.out.println(result.getPlaceName());

but this time the POJO is always empty !

If I changed the interface WeatherService to

        @Remotable
        public interface WeatherService  {
             OMElement GetWeatherByPlaceName(String placeName) throws 
java.rmi.RemoteException;
        }
        
I got the data but this is not transparent anymore!

Any ideas why the GetWeatherByPlaceNameResult object is always empty ?
