在android中使用KSoap时出错？

我正在使用以下代码来调用webservice。我对在android中使用Ksoap非常陌生。我已经设法调用了1个webservice并解析了数据。但是，当我使用相同的代码（我更改了参数soapaction，命名空间…）来解析另一个webservice时，我得到了以下错误。我设置soapaction的参数，名称空间..都设置正确。 我创建了一个调用webservice的方法

public void showdetails()
    {

        String result = "";
        SoapObject resultRequestSOAP = null;
        SoapObject resultRequestSOAPbody =null;

        SoapObject request = new SoapObject(NAMESPACE_Transaction, METHOD_NAME_Transaction);

        request.addProperty("TransactionType","payment");
        request.addProperty("MerchantId","543");
        request.addProperty("amount","0.02");
        request.addProperty("CCNo","4111111111111111");
        request.addProperty("CCExpMonth","11");
        request.addProperty("CCExpYear","22");
        request.addProperty("Source","aa");
        request.addProperty("profileId","788");
        //request.addProperty("ClientIPAddress","120.138.99.2");
       //request.addProperty("GEOCode","0.000000,0.000000");

            //Some more fields that are not mandatory


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

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL_Transaction);
        androidHttpTransport.debug = true;

        try
        {
            androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding= \"UTF-8\"?>");
            androidHttpTransport.call(SOAP_ACTION_Transaction, envelope);
            String requestDumpString = androidHttpTransport.requestDump;
            System.out.println("requestDump : " + requestDumpString);

            resultRequestSOAP = (SoapObject) envelope.bodyIn;
            //  resultRequestSOAP = (SoapObject) envelope.getResponse(); // Output received
            result = resultRequestSOAP.toString(); // Result string
            System.out.println("OUTPUT : " + result);


            if (envelope.bodyIn instanceof SoapFault) 
            {
                String str= ((SoapFault) envelope.bodyIn).faultstring;
                Log.i("TAG", str);
            } else {
                SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
                Log.d("WS", String.valueOf(resultsRequestSOAP));
            }


        } catch (Exception e) {
            e.printStackTrace();
        }

    }

错误如下：

java.lang.ClassCastException: org.ksoap2.SoapFault cannot be cast to org.ksoap2.serialization.SoapObject

有人能帮我解决这个问题吗？我已经搜索了很多，但还没有解决。当我呼叫其他Web服务时，它会将信封返回给我。bodyIn。

我编辑了你的代码，请像这样尝试

SoapObject request = new SoapObject(NAMESPACE_Transaction,
            METHOD_NAME_Transaction); // set up request
    request.addProperty("TransactionType","payment");
    request.addProperty("MerchantId","543");
    request.addProperty("amount","0.02");
    request.addProperty("CCNo","4111111111111111");
    request.addProperty("CCExpMonth","11");
    request.addProperty("CCExpYear","22");
    request.addProperty("Source","aa");
    request.addProperty("profileId","788");
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11); // put all required data into a soap
    // envelope
    // envelope.dotNet = true; This is needed else gives error - 42,
    // parameter is not recognised!!
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request); // prepare request
    AndroidHttpTransport httpTransport = new AndroidHttpTransport(
            URL_Transaction);
    httpTransport.call(SOAP_ACTION_Transaction, envelope);

    SoapObject result = (SoapObject) envelope.getResponse();
      System.out.println(result.toString());

SoapFault表示您的信封。bodyIn是错误的描述。我也知道，当我尝试执行resultRequestSOAP.toString时，错误就在那一行。我得到以下错误SoapFault-faultcode:'soap:Server'faultstring:'System.Web.Services.Protocols.SoapException:服务器无法处理请求。-->System.NullReferenceException:对象引用未设置为对象的实例。您能告诉我需要做什么更改吗？您能检查您的服务器需要什么类型的请求参数吗？您的服务器需要xml标记中的请求吗。嵌入在xml标记中的请求？？检查您的请求应采用何种形式。可能这将帮助您解决此问题仍然是同一个错误@Amit.get错误。实际问题是我没有传递所有参数。其他字段必须在android代码中传递。虽然如果没有在浏览器中输入，它将调用Web服务。谢谢大家。我告诉过您检查请求参数，您也提出了同样的要求昨天的问题将其作为另一个问题发布

SoapObject request = new SoapObject(NAMESPACE_Transaction,
            METHOD_NAME_Transaction); // set up request
    request.addProperty("TransactionType","payment");
    request.addProperty("MerchantId","543");
    request.addProperty("amount","0.02");
    request.addProperty("CCNo","4111111111111111");
    request.addProperty("CCExpMonth","11");
    request.addProperty("CCExpYear","22");
    request.addProperty("Source","aa");
    request.addProperty("profileId","788");
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11); // put all required data into a soap
    // envelope
    // envelope.dotNet = true; This is needed else gives error - 42,
    // parameter is not recognised!!
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request); // prepare request
    AndroidHttpTransport httpTransport = new AndroidHttpTransport(
            URL_Transaction);
    httpTransport.call(SOAP_ACTION_Transaction, envelope);

    SoapObject result = (SoapObject) envelope.getResponse();
      System.out.println(result.toString());
