then code in 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 = "";         try {             androidhttptransport.call(soap_action_1, envelope);             soapprimitive  response = (soapprimitive) envelope.getresponse();             = 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 menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }  } 

anyone can me solve this?

i have updated code

webserviceinterface.java

package com.med.dic.ws;  import javax.jws.webmethod; import javax.jws.webservice; import javax.jws.soap.soapbinding; import javax.jws.soap.soapbinding.style;  @webservice @soapbinding(style = style.rpc) public interface webserviceinterface {      @webmethod string getmed(int id);     @webmethod string gethelloworld(string a); } 

webservice.java

package com.med.dic.ws;  import javax.jws.webmethod; import javax.jws.webservice;  import com.med.dic.dao.medicinedao;  @webservice(endpointinterface = "com.med.dic.ws.webserviceinterface") public class webservice implements webserviceinterface {      private medicinedao medicinedao;     @webmethod(exclude=true)     public void setmedicinedao(medicinedao medicinedao) {         this.medicinedao = medicinedao;     }      @override     @webmethod(operationname="getmed")     public string getmed(int id) {         string medname = medicinedao.searchbyid(id).getmedname();         return medname;     }      @override     @webmethod(operationname="gethelloworld")     public string gethelloworld(string a){         return "jax-ws + spring! " + a;     } }
