如何從android客戶端使用kso​​ap2調用基於java的wsdl webservice？

Question

我是android新手。 我必須使用kso​​ap2從android客戶端調用基於java的wsdl webservice。 任何人都可以幫助我嗎？ 我嘗試調用，但得到XmlPullParserException。

這裏是一個類，我用KSOAP

import java.io.IOException; 

import org.ksoap2.SoapEnvelope; 
import org.ksoap2.serialization.SoapObject; 
import org.ksoap2.serialization.SoapPrimitive; 
import org.ksoap2.serialization.SoapSerializationEnvelope; 
import org.ksoap2.transport.HttpTransportSE; 
import org.xmlpull.v1.XmlPullParserException; 

import android.os.AsyncTask; 
import android.util.Log; 
import searchparams.MetaData; 

public class RequestTools { 

    public interface ResultListener{ 

     /** 
     * 
     * @param result 
     * @param mode also used for error 
     */ 
     public void onReadable(String result, int mode); 
    } 

    private static KSOAPAsync mSearchAsync = null; 

    public static final int ERROR_UNDEFINED = -1; 
    public static final int MODE_CALCULATOR = 0; 
    public static final int MODE_WEATHER = 1; 

    public static void startGetWeatherData(ResultListener listener, String city){ 

     mSearchAsync = new KSOAPAsync(listener, MODE_WEATHER); 
     mSearchAsync.execute(city); 
    } 

    public static void startGetAddition(ResultListener listener, String x, String y){ 

     mSearchAsync = new KSOAPAsync(listener,MODE_CALCULATOR); 
     mSearchAsync.execute(x,y); 
    } 

    public static class KSOAPAsync 
     extends AsyncTask<String, Boolean, SoapPrimitive> { 

     private ResultListener resultListener = null; 

     private int modeType = -1; 

     public KSOAPAsync(ResultListener listener, int mode) { 
      resultListener = listener; 
      modeType = mode; 
     }  

     @Override 
     protected SoapPrimitive doInBackground(String... params) { 

      SoapPrimitive result = null; 

      switch(modeType){ 

       case RequestTools.MODE_CALCULATOR: 

        result = getCalculation(
          Integer.valueOf(params[0]), 
          Integer.valueOf(params[1])); 

        break; 

       case RequestTools.MODE_WEATHER: 

        result = getWeather(params[0]); 

        break; 

       default: 
      } 



      return result; 
     } 

     private SoapPrimitive getCalculation(int x, int y){ 

      SoapObject request = new SoapObject(
        MetaData.Calculator.NAMESPACE, 
        MetaData.Calculator.METHOD_NAME); 

      request.addProperty("x",x); 
      request.addProperty("y",y); 

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

      envelope.setOutputSoapObject(request); 

      HttpTransportSE androidHttptransport = new HttpTransportSE(
        MetaData.Calculator.URL); 

      SoapPrimitive result = null; 

      try { 
       androidHttptransport.call(MetaData.Calculator.SOAP_ACTION, 
         envelope); 

       result = (SoapPrimitive)envelope.getResponse(); 

       Log.i(TAG,""+result.toString()); 

      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (XmlPullParserException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

      return result; 
     } 

     private SoapPrimitive getWeather(String city){ 

      SoapObject request = new SoapObject(
        MetaData.Weather.NAMESPACE, 
        MetaData.Weather.METHOD_NAME); 

      request.addProperty("City", city); 

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

      envelope.setOutputSoapObject(request); 

      HttpTransportSE androidHttptransport = new HttpTransportSE(
        MetaData.Weather.URL); 

      SoapPrimitive result = null; 

      try { 
       androidHttptransport.call(MetaData.Weather.SOAP_ACTION, 
         envelope); 

       result = (SoapPrimitive)envelope.getResponse(); 

       Log.i(TAG,""+result.toString()); 

      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (XmlPullParserException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

      return result; 
     } 

     private static final String TAG = RequestTools.class.getSimpleName(); 

     @Override 
     protected void onPostExecute(SoapPrimitive result) { 

      if(result == null){ 
       resultListener.onReadable(null,RequestTools.ERROR_UNDEFINED); 
      }else{ 
       resultListener.onReadable(result.toString(),modeType); 
      } 
     } 
    } 

}
