org.xmlpull.v1.XmlPullParserException: expected: START_TAG using ksoap2-android

[Pedro]

Hello, i'm trying to access a WebService and i keep getting this
error.
The error is in the line:


androidHttpTransport.call(SOAP_ACTION,envelope);

Someone knows why?

Do you have a null response? Debug as described in the wiki and
checkout the responsedump.

[Pedro]

sorry, but I don't find how to debug :/
Meanwhile, in the url that i was passing i removed the "?wsdl" in the
end of the file and it seems that it makes the request (no error is
given) but when i try to print the response i get an error.

try {

androidHttpTransport.call(SOAP_ACTION, envelope);

SoapObject result = (SoapObject) envelope.getResponse();
Log.v(TAG, "REQUEST RESULT: " + result.toString());

and i get

04-27 20:26:55.129: WARN/System.err(956): SoapFault - faultcode:
'soap:Server' faultstring: 'argument type mismatch while invoking
public abstract
com.criticalsoftware.wiccore.wise.entities.resources.Equipment
com.criticalsoftware.wiccore.wise.business.webservice.SharedWebService.getEquipment(int)
with params [192].' faultactor: 'null' detail: null

[Manfred Moser]

Thats the error message from the server..

[Pedro]

Yes , i know that's an error from the server.
I changed the response method to:

try {

androidHttpTransport.call(SOAP_ACTION, envelope);

SoapObject response = (SoapObject)envelope.bodyIn;

and now the error is 04-28 01:56:05.332: WARN/System.err(305):
java.lang.ClassCastException: org.ksoap2.SoapFault

The requestdump is:
<v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://
schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://
schemas.xmlsoap.org/soap/envelope/"><v:Header /
><v:Body><n0:getEquipment id="o0" c:root="1" xmlns:n0="http://
webservice.business.wise.wiccore.criticalsoftware.com/"><arg0
i:type="d:string">192</arg0></n0:getEquipment></v:Body></v:Envelope>

and the response comes with error. I'm calling the method getEquipment
and i add a property using: request.addProperty("arg0",
"192");

Don't know why i get this SoapFault ..

It's just the standard message of ClassCastException, the name of the class that could not be casted. If the server returns an error for your request, envelope.bodyIn will be a SoapFault instance, not a SoapObject. So you get an exception on the line where you cast bodyIn to SoapObject.

[Manfred Moser]

A good approach is to just do something along these lines (pseudo code)

Object response = envelope.getResponse();

if (response instanceof SoapFault) {

} else if (response instanceof SoapPrimitive) {
// some webservices just return this..
} else if (response instanceof SoapObject) {
// do the normal parsing.
}

Also... dont use bodyIn directly .. call getResponse().
