applet java e web service Axis

[thegirl]

Salve, ho un Applet Java che richiama un web service Axis ma quando la mando in esecuzione mi dà questo errore

AxisFault

c'è qualcuno che mi sa dire da cosa potrebbe dipendere?
Grazie

Così si evince solamente che la connessione non viene effettuata perchè il server verso cui ci si sta collegando ha rifiutato la connessione.

Ad ogni modo, senza avere il codice dell'applet, né del WebService, risulta impossibile risalire ad una causa più specifica.


Ciao.

La chiamata al WebService è stata generata in maniera automatica da WSDL2 Java ne riporto il codice:

public class ProfileControllerServiceLocator extends org.apache.axis.client.Service implements
it.uniba.serlab.clientTabula.clientProfile.Profile ControllerService {

...

private java.lang.String ProfileTabulaWS_address = "http://localhost:8080/axis/services/ProfileTabulaWS";

public it.uniba.serlab.clientTabula.clientProfile.Profile Controller getProfileTabulaWS() throws

javax.xml.rpc.ServiceException {
java.net.URL endpoint;
try {
endpoint = new java.net.URL(ProfileTabulaWS_address);
}
catch (java.net.MalformedURLException e) {
throw new javax.xml.rpc.ServiceException(e);
}
return getProfileTabulaWS(endpoint);
}


public it.uniba.serlab.clientTabula.clientProfile.Profile Controller getProfileTabulaWS(java.net.URL

portAddress) throws javax.xml.rpc.ServiceException {
try {
it.uniba.serlab.clientTabula.clientProfile.Profile TabulaWSSoapBindingStub _stub = new

it.uniba.serlab.clientTabula.clientProfile.Profile TabulaWSSoapBindingStub(portAddress, this);
_stub.setPortName(getProfileTabulaWSWSDDServiceNam e());
return _stub;
}
catch (org.apache.axis.AxisFault e) {
return null;
}
}

...

}

public class ProfileTabulaWSSoapBindingStub extends org.apache.axis.client.Stub implements

it.uniba.serlab.clientTabula.clientProfile.Profile Controller {

private java.util.Vector cachedSerClasses = new java.util.Vector();
private java.util.Vector cachedSerQNames = new java.util.Vector();
private java.util.Vector cachedSerFactories = new java.util.Vector();
private java.util.Vector cachedDeserFactories = new java.util.Vector();

static org.apache.axis.description.OperationDesc [] _operations;

static {
_operations = new org.apache.axis.description.OperationDesc[11];
_initOperationDesc1();
_initOperationDesc2();
}

...

public void startConnection(java.lang.String database, java.lang.String host, java.lang.String port,

java.lang.String user, java.lang.String password) throws java.rmi.RemoteException {
if (super.cachedEndpoint == null) {
throw new org.apache.axis.NoEndPointException();
}
org.apache.axis.client.Call _call = createCall();
_call.setOperation(_operations[0]);
_call.setUseSOAPAction(true);
_call.setSOAPActionURI("");
_call.setSOAPVersion(org.apache.axis.soap.SOAPCons tants.SOAP11_CONSTANTS);
_call.setOperationName(new javax.xml.namespace.QName("http://profile.business", "startConnection"));

setRequestHeaders(_call);
setAttachments(_call);
try { java.lang.Object _resp = _call.invoke(new java.lang.Object[] {database, host, port, user,

password});

if (_resp instanceof java.rmi.RemoteException) {
throw (java.rmi.RemoteException)_resp;
}
extractAttachments(_call);
} catch (org.apache.axis.AxisFault axisFaultException) {
throw axisFaultException;
}
}

...

}

eseguendo il debug si nota che già quando esegue:

it.uniba.serlab.clientTabula.clientProfile.Profile TabulaWSSoapBindingStub _stub = new

it.uniba.serlab.clientTabula.clientProfile.Profile TabulaWSSoapBindingStub(portAddress, this);

genera l'eccezione ClassNotFoundException ma continua l'esecuzione

N.B.
Sono nuova sia alla tecnologia dei WebService sia a quella delle applet, questo è codice ereditato,spero di essere stata più chiara.

Ti dovresti innanzitutto assicurare che il web service sia correttamente disponibile.
Sicuro che il web server sia in esecuzione ?

Prova a fare una chiamata fuori dall'applet scrivendoti una classe al volo in modo da assicurartente

[thegirl]

Gli stessi WS li utilizzo in un'altra applicazione web e lì non mi danno alcun problema, cmq ho anche provato a testare i WS e sono attivi.

[isAlreadyInUse]

Puo essere un problema legato alla security?

[thegirl]

Cosa dovrei fare? Certificare l'applet?

[isAlreadyInUse]

firmarla

[thegirl]

grazie mille...proverò questa soluzione
