ksoap : 인수 예외가있는 서비스 호출

Question

String을 인수로 사용하는 SOAP 서비스가 있으며이를 내 andrid 코드에서 호출합니다. 내 예제 코드에서는, 내가 그것을 위해 AsyncTask를 사용합니다. doInBackground 메서드에서 나는 두 개의 서비스를 호출한다 : 첫 번째 것은 args가없는 데이터를 검색하고, 두 번째는 argument를 String으로 취하고 void를 반환한다.

무슨 일이야 : 내가 두 번째 서비스를 호출 할 때

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
     SoapEnvelope.VER11); 
envelope.setOutputSoapObject(request); 
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
androidHttpTransport.call(SOAP_ACTION, envelope); 
Vector<SoapObject> result = (Vector<SoapObject>) envelope 
     .getResponse(); 
request = new SoapObject(NAMESPACE, METHOD_NAME2); 
PropertyInfo property=new PropertyInfo(); 
property.setName("lastDate"); 
property.setValue("2013/09/10 14:51:08"); 
property.setValue(java.lang.String.class); 
request.addProperty(property); 
envelope.setOutputSoapObject(request); 
androidHttpTransport.call(SOAP_ACTION, envelope); 

하지만 (METHOD_NAME2는) 나는 필연의 오류를 얻기?

Answer 1

난 당신 문제가 HttpTransportSE 그래서 첫 번째 연결을 종료되지 않는 것입니다 생각 :

HttpTransportSE http = new HttpTransportSE(URL); 
System.setProperty("http.keepAlive", "false"); 
http.call(SOAP_ACTION, envelope); 

내가 테스트하고 작동! 감사합니다.
