我创建了一个简单的Web服务来连接Android设备。我已经使用了JAX-WS，请遵循以下指南：http://www.mkyong.com/webservices/jax-ws/jax-ws-spring-integration-example/
当我在客户端上运行时，它是正常的，但在设备上，我有一个错误。它是“SoapFault - faultcode：“S：服务器”错误字符串：“java.lang.非法参数异常”错误指示符：'null'详细信息：******
存在WSDL文件

然后是我的代码在android

package com.example.smdtestwebservice;

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.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.os.StrictMode;
import android.view.Menu;
import android.widget.Toast;

public class MainActivity extends Activity {

    private String METHOD_NAME_1 = "getMed";
    private String NAME_SPACE = "http://ws.dic.med.com/";
    private String SOAP_ACTION_1 = NAME_SPACE + METHOD_NAME_1;
    private static final String URL = "http://192.168.248.1:8080/Webservice1/smd?wsdl";

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (android.os.Build.VERSION.SDK_INT > 9) {
            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
            StrictMode.setThreadPolicy(policy);
        }

        SoapObject request = new SoapObject(NAME_SPACE, METHOD_NAME_1);
        request.addProperty("arg0", 1);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        String a = "";
        try {
            androidHttpTransport.call(SOAP_ACTION_1, envelope);
            SoapPrimitive  response = (SoapPrimitive) envelope.getResponse();
            a = response.toString();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        }
        Toast.makeText(this, a, Toast.LENGTH_SHORT).show();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

有谁能帮我解决这个问题吗？
我已更新代码
