JSON Parsing on BlackBerry - json

Question

I'm working on parsing JSON on BlackBerry using org.json.me, but I can't parsing the result. Simulator Console says: No Stack Trace
Here's my code to parsing JSON after receiving JSON string from my restclient
try {
JSONObject outer=new JSONObject(data);
JSONArray ja = outer.getJSONArray("status");
JSONArray arr=ja.getJSONArray(0);
System.out.println(arr);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
And here's the piece code to get JSON from the server
public PromoThread(final String url, final ResponseCallback callback){
Thread t = new Thread(new Runnable(){
public void run() {
waitScreen = new WaitPopupScreen();
System.out.println("Log >> Promo thread run...");
synchronized (UiApplication.getEventLock()){
UiApplication.getUiApplication().pushScreen(waitScreen);
}
//network call
try {
conn = (HttpConnection) new ConnectionFactory().getConnection(url).getConnection();
conn.setRequestMethod(HttpConnection.GET);
conn.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Confirguration/CLDC-1.0");
if (conn.getResponseCode() == HttpConnection.HTTP_OK) {
in = conn.openInputStream();
// parser.parse(in, handler);
//buff.append(IOUtilities.streamToBytes(in));
//result = buff.toString();
results = new String(IOUtilities.streamToBytes(in));
//System.out.println("Log >> Result: " + results);
UiApplication.getUiApplication().invokeLater(
new Runnable() {
public void run() {
//UiApplication.getUiApplication().popScreen(waitScreen);
callback.callback(results, waitScreen);
}
});
}
} catch (Exception ex) {
ex.printStackTrace();
} finally {
try {
if (in != null) {
in.close();
}
conn.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
});
//start thread
t.start();
}
Thanks for your help
