In your binding element, try going directly to the service endpoint, like this:
<binding.ws
wsdlElement="http://prova.netbureau.it/#wsdl.port(provaWSService/provaWSPort)"
uri="http://localhost:8080/ProvaWS/provaWS"/>

ok,
i have modified the client:
ProvaWS provaws = ((Client)node).getService(ProvaWS.class,
"ProvaWSExtService"); <- the component name not the name of the serviceClass
but now i have a strange exception, a null pointer exception:

and so another reflection error...
WHAT's wrong now?? :( :''(
this is my composite file:
<composite xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903";
targetNamespace="http://sample";
xmlns:sample="http://sample";
xmlns:wsdli="http://www.w3.org/2004/08/wsdl-instance";
name="SCAExample">
<!-- external web service JAX-WS -->
<component name="ProvaWSExtService">
<implementation.java class="it.netbureau.prova.ProvaWSImpl"/>
<reference name="ProvaWSService">
<binding.ws
wsdlElement="http://prova.netbureau.it/#wsdl.port(provaWSService/provaWSPort)"
wsdli:wsdlLocation="http://localhost:8080/ProvaWS/provaWS?wsdl"/>
</reference>
</component>
thanks
and class that implemtent the interface of service that esposes remoted
services(ProvaWs):
@Service(ProvaWS.class)
public class ProvaWSImpl implements ProvaWS{
@Reference
public ProvaWS ProvaWSService;
public Integer addws(int num1, int num2) {
System.out.println("***ProvaWSService is " + ProvaWSService);
return ProvaWSService.addws(num1, num2);
}
}
