  • 0

I am using KSOAP2 in my android application, and when I try to perform a particular webservice request, I got this “double ID” exception. Where i’am going wrong ? Please help me.

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(SOAP_ADDRESS);

        SoapPrimitive response = null;
        try {   
          androidHttpTransport.call(SOAP_ACTION, envelope); //<<--- Getting exception here
          response = (SoapPrimitive)envelope.getResponse();

        } catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(getApplicationContext(), e+"", Toast.LENGTH_LONG).show();
        }

    Here is nice example that might help you: Click Here

    Here is my quick fix to this issue:

    SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);

SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
soapEnvelope.setOutputSoapObject(Request);
soapEnvelope.dotNet = true;


List<Integer> companies =  new ArrayList<Integer>();
companies.add(65);
companies.add(66);
companies.add(67);

Request.addProperty("name", "test1");
SoapObject soapCompanies = new SoapObject(NAMESPACE, "companies");
for (Integer i : companies){
    soapCompanies.addProperty("int", i);
}
Request.addSoapObject(soapCompanies);

    Output XML:

    <n0:companies xmlns:n0 = "http://tempuri.org/">
            <int i:type = "d:int">65</int>
            <int i:type = "d:int">66</int>
            <int i:type = "d:int">67</int>
</n0:companies>
<name i:type = "d:string">test1</name>
