ClassCastException on response

[Anagnostes]

My Ksoap version is 2.6.3.

Hi, i'm trying to cast a response as an object and there is no way i
can't achieve it. I post my code:

first i've created the KvmSerializable class for testing a simple
object with one string.

public class TRespostaArticle implements KvmSerializable
{
public String Caducitat;

public TRespostaArticle(SoapObject obj){
Caducitat = "";
}

public TRespostaArticle(){
Caducitat = "";
}


public TRespostaArticle(String p_Caducitat,String p_Error,
String p_Missatge) {
Caducitat = p_Caducitat;
}

public Object getProperty(int arg0) {

switch(arg0)
{
case 0:
return "";
}
return null;
}

public int getPropertyCount() {
return 1;
}

public void getPropertyInfo(int index, Hashtable arg1,
PropertyInfo arg2) {
switch(index)
{
case 0:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Caducitat";
break;
default:break;
}
}

public void setProperty(int index, Object value) {
switch(index) {
case 0:
Caducitat = value.toString();
break;
default: break;
}
}

}


Then i make the call like this.. the call is correct and i get the
response, but no way i can parse it:

SoapObject request = new SoapObject(NAMESPACE,
METHOD_NAME); //set up request
request.addProperty("p_empresa_guid", "{E5BD15A1-C3FA-413D-
A8E1-31EC60E30BD8}");
request.addProperty("p_cadena", "7013");
request.addProperty("p_Magatzem_Id", "5");
SoapSerializationEnvelope soapEnvelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
soapEnvelope.setOutputSoapObject(request);

HttpTransportSE httpTransport = new HttpTransportSE(URL);
httpTransport.debug = true;
try {
httpTransport.call(SOAP_ACTION, soapEnvelope);
SoapObject response = (SoapObject)soapEnvelope.bodyIn; //get
response
TRespostaArticle t_s1 = (TRespostaArticle)
response.getProperty("TRespostaArticle");
String t1b = t_s1.toString();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

The httpTransport requestDump is :

<v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://

p_cadena><p_Magatzem_Id>5</p_Magatzem_Id></
n0:Get_Article_Inventari_Cadena></v:Body></v:Envelope>\r\n

And responseDump is:

<?xml version="1.0"?>\r\n<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://
schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/

Caducitat></NS2:TRespostaArticle><return href="#1"/></
NS1:Get_Article_Inventari_CadenaResponse></SOAP-ENV:Body></SOAP-
ENV:Envelope>\r\n

and the response object i recive is:

Get_Article_Inventari_CadenaResponse{TRespostaArticle=TRespostaArticle{Caducitat=hola; };
return=TRespostaArticle{Caducitat=hola; }; }

I get all class of when i test it
Caused by: java.lang.ClassCastException:
org.ksoap2.serialization.SoapObject
or ..
Caused by: java.lang.ClassCastException: java.lang.String

Is there anyone who can tell me what i'm doing wrong.

Thank you very much

You got some more details where the problem happens? My observations would be that you are using bodyIn instead of getRepsonse().

Try that and report back with more details..

Ok, i've tried getResponse with same results.

I paste the code again and debug strings, with a temporal URL for you
if you want to see the WSDL.

private static final String METHOD_NAME =
"Get_Article_Inventari_Cadena";
private static final String SOAP_ACTION = "urn:InventarisIntf-
IInventaris#Get_Article_Inventari_Cadena";
private static final String NAMESPACE = "urn:InventarisIntf-
IInventaris";
private static final String URL = "http://lab.activainfo.net/
PDAWebServicesISAPI.dll/soap/IInventaris";
.....

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); //set up
request
request.addProperty("p_empresa_guid", "{E5BD15A1-C3FA-413D-
A8E1-31EC60E30BD8}");
request.addProperty("p_cadena", "7013");
request.addProperty("p_Magatzem_Id", "5");
SoapSerializationEnvelope soapEnvelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
soapEnvelope.setOutputSoapObject(request);

soapEnvelope.addMapping(NAMESPACE,
TRespostaArticle.class.getSimpleName(), new
TRespostaArticle().getClass());

HttpTransportSE httpTransport = new HttpTransportSE(URL);

httpTransport.debug = true; //this is optional, use it if
you don't want to use a packet sniffer to check what the sent message
was

try {
httpTransport.call(SOAP_ACTION, soapEnvelope);
TRespostaArticle response = (TRespostaArticle)
soapEnvelope.getResponse(); //get response
.....
The exception is in this last line:

It's a Delphi 2010 dll webservice made with soap.

My intuation says it's a namespace problem, so i've tried:

soapEnvelope.addMapping("urn:utils_inventaris",
TRespostaArticle.class.getSimpleName(), new
TRespostaArticle().getClass());

But this throws another exception in the line
httpTransport.call(SOAP_ACTION, soapEnvelope);

help more sorry.

THank you very much.

Debug right where it says the problem occurs and take it from there ..
also confirm that the response is what you expected it to be. Seems
like something is wrong when it tries to instantiate your
TRespostaArticle object..

[Manfred Moser]

Sorry... I misread the stack trace.. must be something else it is
trying to instantiate. You will have to debug this into the framework
code to see what is going on.

Just hook the library source code into your project and debug it.

manfred

[Anagnostes]

Sorry, i send my last email wrong.

What do you mean debug from there?

I've debugged many times with many variations and allways throws that
two class exceptions . But i can't debug your code because i think
there is no source code only jars.So i can't see what's happening
behind the scene.

Caused by:
java.lang.ClassCastException: org.ksoap2.serialization.SoapObject

Caused by:
java.lang.RuntimeException: java.lang.InstantiationException:
testAndroid.namespace.TestAndroidActivity$TRespostaArticle

How can i attach the source code to the jar? I have ksoap2-android-
assembly-2.6.3-jar-with-dependencies.jar but it ask for source code...
where is it?

What object is it when this cast fails?

Same here... what is it trying to instantiate? Where?

That depends on the IDE and your tool chain. If you build your app
with Android Maven Plugin it does it all automatically with m2eclipse
or intellij. Otherwise you have to manually hook it in. The source is
on github in source format or on google code as sources jars for the
different sub libraries.. yes.. with ant this is painful ..

Thank you very much, i'll try to fix my error.
