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 服务开发应用程序以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，但是当我将它运行到我的手机时，什么都没有发生。甚至数据也没有发送到服务器。请帮助我并为此源代码提供一些指导。

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，直到 ht.call(soapAction,envelope);之后我没有得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从设备访问互联网和其他访问权限。

所以请帮助我，并为我提供一些步骤，以便在肥皂信封的帮助下上传数据。

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