Comment obtenir des données du serveur localhost en utilisant Blackberry Simulator

Question

Je veux obtenir des données du serveur localhost en utilisant le simulateur Blackberry. Mon serveur donne des données dans un fichier JSON. Comment je peux afficher les données dans le simulateur Blackberry et comment analyser JSON en String. Je souhaite que quelqu'un m'aide.

Ceci est mon code source pour le serveur.

<?php 
    require('db.php'); 
    $query="select*from penarikan"; 
    $hasil=mysql_query($query); 
    if(mysql_num_rows($hasil)>0) 
    { 
     while($data=mysql_fetch_array($hasil)) 
     { 
      $x[]=$data; 
     } 

    } 
    echo(json_encode($x)); 
?> 

et voici mon code source pour Blackberry

package com.irwan.bb.pa; 

import java.io.InputStream; 
import java.io.InputStreamReader; 

import javax.microedition.io.Connector; 
import javax.microedition.io.HttpConnection; 

import org.json.me.JSONObject; 

import net.rim.device.api.ui.component.LabelField; 
import net.rim.device.api.ui.container.MainScreen; 

public class ScreenViewPenarikan extends MainScreen { 
    HttpConnection httpconnection; 
    InputStream inputStream; 


    public ScreenViewPenarikan() { 
     super(MainScreen.VERTICAL_SCROLL | MainScreen.VERTICAL_SCROLLBAR); 
     runJson(); 
    } 

    public void runJson() 
    { 
     try { 

      String url="http://127.0.0.1:80/proyek_akhir/view_penarikan.php;deviceside=true"; 
      System.out.println(url); 

      //connect to server 
      httpconnection=(HttpConnection)Connector.open(url); 
      inputStream=httpconnection.openDataInputStream(); 

      if(httpconnection.getResponseCode()==HttpConnection.HTTP_OK) 
      { 
       //add(new LabelField("Ada konesksi")); 
       InputStreamReader reader= new InputStreamReader(inputStream,"UTF-8"); 
       int readCharacter; 
       StringBuffer responseBuffer = new StringBuffer(); 
       while ((readCharacter = reader.read()) != -1) { 
        responseBuffer.append((char) readCharacter); 
        httpconnection.close(); 
        inputStream.close(); 
        reader.close(); 
        String responseMessage = new String(responseBuffer); 
        JSONObject object = new JSONObject(responseMessage); 
        add(new LabelField(object)); 


       } 
      } 
      else{ 
       //add(new LabelField("Koneksi tidak ada")); 
      } 

     } catch (Exception e) { 
      // TODO: handle exception 
     } 
    } 

}

essayer ce -

[ 
    { 
     "0": "1", 
     "1": "2", 
     "2": "2013-06-30", 
     "3": "30110089", 
     "id_penarikan": "1", 
     "jlh_nominal": "2", 
     "tanggal‌": "2013-06-30", 
     "no_rekening": "30110089" 
    } 
] 

et

while ((readCharacter = reader.read()) != -1) { 
    responseBuffer.append((char) readCharacter); 
    } 

    String val=""; 
    String responseMessage = new String(responseBuffer); 
    JSONArray j=new JSONArray(responseMessage); 
    JSONObject j0=j.getJSONObject(0); 
    val=j0.getString("id_penarikan"); 
    add(new LabelField(val));
