Hi, i'm trying to access a deployed group of services, which are shown as active, and i can see their wsld(s) (with axis2-1.3 in three different versions: bin. war. nightly build); however, every client i've written until now throws this kind of error (as follows), so what am i doing wrong?
thank you.
error message:

one of the implementation classes; this
one exposes only the getEtichetta method:
public final class Protocollatore implements ProtocolService {
private static Protocollo protocollo;
private static boolean set = false;
public Protocollatore() {
if(!set) {
protocollo = new Protocollo();
set = true;
}
}

if(set){
protocollo.AddOne();
Protocollo p = new Protocollo(protocollo.getValue());
return p;
} else return null;
}
public synchronized OMElement getEtichetta (OMElement _null) {
OMElement method = null;
try {
OMFactory fac = OMAbstractFactory.getOMFactory();
if(set){
protocollo.AddOne();
Etichetta e = new Etichetta(protocollo.getValue());
method = e.getOMElement();
} else {
OMNamespace ens =
fac.createOMNamespace("http://soap-shop.com/error","error";);
method = fac.createOMElement("InitFault", ens);
method.addChild(fac.createOMText(method, "Errore :
Protocollatore non
inizializzato"));
}
} catch (XMLStreamException xse) {
System.out.println("Protocollatore.getEtichetta() :
"+xse.toString());
}
return method;
}
protected synchronized Etichetta Etichetta ( ) {
if(set){
protocollo.AddOne();
Etichetta e = new Etichetta(protocollo.getValue());
return e;
} else return null;
}
}
The client class for this service:
public class ProtocolClient {
public static OMElement getEtichetta() throws AxisFault {
OMElement payload = getNewOMElement("Etichetta");
OMElement result = doIt(payload, "getEtichetta");
return result;
}
private static EndpointReference targetEPR =

"http://localhost:8180/axis2/services/ProtocolService";);
public static void main(String[] args) {
try {
OMElement payload = getNewOMElement("Vuoto");
OMElement result = getEtichetta();
String response = result.getFirstElement().getText();
} catch (Exception e) {
e.printStackTrace();
}
}
private static OMElement doIt(OMElement payload, String action) throws
AxisFault {
Options options = new Options();
options.setTo(targetEPR);
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setAction("urn:"+action);
ServiceClient sender = new ServiceClient();
sender.setOptions(options);
OMElement result = sender.sendReceive(payload);
return result;
}
private static OMElement getNewOMElement(String tag) {
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs =
fac.createOMNamespace("http://soap-shop.com/ProtocolService";,
"ProtocolServiceNS");
OMElement result = fac.createOMElement(tag,omNs);
return result;
