[axis] NullPointer przy deserializacji

[Tomasz Minkowski]

Witam.
Odpaliłem w axisie usługę sieciową .jws (pobiera i zwraca zwraca
stringa). Wszystko od strony serwera jest ok (sprawdzone TCPMonem)

Klient usługi wygląda tak jak przykład na ws.apache.org:

public class WsClient {

public String callService() throws Exception {

String target = "http://localhost:8080/axis/Fws.jws";

Service service = new Service();

Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new URL(target));
call.setOperationName(new QName("http://siala.la/", "doIt"));

String ret = (String) call.invoke(new Object[] { "Pupa" });
return ret;
}

public static void main(String[] args) throws Exception {
// TODO code application logic here
WsClient w = new WsClient();
System.out.println(w.callService());
}

}

I po odpaleniu wywala się (z klienta):
