  SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
  envelope.bodyOut = request;
  String serviceURL = "http://192.168.0.169:1433/axis2/services/HospitalProServer";
  AndroidHttpTransport transport = new AndroidHttpTransport(serviceURL);
  transport.debug = true;
  transport.call(serviceName, envelope);//这里发生异常

服务端代码：public class HospitalProServer {

      public HospitalProServer(){}

                public Object sayHello(){
return "hello";
      }
