在黑莓中使用 ksoap 开发应用程序

Question

我是黑莓开发的新手。我的任务是使用 Web 服务开发应用程序来查找位置并将数据发送到服务器。

我已经为肥皂请求开发了以下代码，但是当我将其运行到我的手机时，什么也没有发生。甚至数据也没有发送到服务器。请帮助我并提供一些有关此源代码的指南。

final class MyScreen extends SplashScreen  {

    private String serviceUrl = "myurl/GPStracker.asmx";
    private String serviceNamespace = "http://tempuri.org/";
    private String soapAction = "http://tempuri.org/GPSUnikeylogin";
    private String methodName = "GPSUnikeylogin";

    private String imei = GPRSInfo.imeiToString(GPRSInfo.getIMEI(), false);

    private BasicEditField roundedBorderEdit = null;
    private ButtonField bf;
    private String responseBody;
    Hashtable persistentHashtable; 
    PersistentObject persistentObject;
    static final long KEY = 0x9df9f961bc6d6baL;

    public MyScreen(Bitmap popup, int seconds) {
            super(Bitmap.getBitmapResource("bg.png"), 5);

                //persistentObject = PersistentStore.getPersistentObject(KEY);
                 roundedBorderEdit = new BasicEditField();
                 roundedBorderEdit = new BasicEditField("","",50,EditField.EDITABLE | EditField.FILTER_NUMERIC | EditField.FIELD_HCENTER) {
                     public void paint(Graphics g) {
                         super.paint(g);
                         g.drawRect(0, 0, getWidth(), getHeight());
                     }
                 };
                 add(roundedBorderEdit);

                 bf = new ButtonField ("Register", Field.FOCUSABLE);
                 bf.setChangeListener(new FieldChangeListener(){
                     public void fieldChanged(Field field, int context) {

                         callWebService();

                     }
                 });
                 add (bf);

    }   
    private void callWebService()
    {
        String e =  "123";//MyScreen.this.roundedBorderEdit.getText();
        //Dialog.alert(e.toString());

        SoapObject rpc = new SoapObject(serviceNamespace, methodName);
        //Dialog.alert(rpc.toString());

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        rpc.addProperty("vUnikey",e.toString());
        rpc.addProperty("vImei_No",imei.toString());

        //Dialog.alert(rpc.toString());
        envelope.setOutputSoapObject(rpc);
        envelope.bodyOut = rpc;
        envelope.dotNet = true;
        envelope.encodingStyle = SoapSerializationEnvelope.XSI;

        HttpTransport ht = new HttpTransport(serviceUrl);//+ ";deviceside=true;apn=blackberry.net");

        Dialog.alert(ht.toString());

        //HttpTransport ht = new HttpTransport(serviceUrl);
        ht.debug = true;
        ht.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
        //Dialog.alert("set to xml");
        String result= null;

        try{

            ht.call(soapAction, envelope);
            Dialog.alert(ht.toString());
            result = (envelope.toString());
            Dialog.alert(result.toString());
        }

        catch (org.xmlpull.v1.XmlPullParserException ex2) {
        }

        catch (Exception ex) {
             String bah = ex.toString();
             System.out.println(bah);
        }
    }
} 

在上面的代码中，我接到电话直到 ht.call(soapAction, 信封);之后我没有收到服务器的任何响应。而且我也没有获得正确的方法来授予互联网访问权限和设备的其他访问权限。

因此，请帮助我并为我提供一些借助肥皂信封上传数据的步骤。

您可能想查看 ksoap2-android 项目。它的代码仍然兼容 Java 1.3/Java ME，并且应该可以在黑莓设备上正常工作。
