Problem is when I get first response and I process it, while loop fails for the second one. How do I keep the connection open and process all events received through socket pipeline?

MDM (Mobile Device management) in J2ME

I want to implement MDM in J2ME. Whenever I update App, I am able to upload New App in Mobile, I can upload it successfully. But My Problem is that, I want to replace existing App and then want to upload new App. As of now I can add App on Device with Different name (Same App Name is not working) but cant replace App.
Here is my code for MDM:
public void getUpdateApp() {
new Thread(new Runnable() {
public void run() {
try {
DataHelper dh = new DataHelper(parent);
dh.openRecord();
String response_rms = dh.getupdateAppinfo_str();

UserInfo userInfo = getUserInfo();
String data = "AppCode=" + AppData.appCode+ "&CurrentVersion=" + AppData.currentversion
+ "&TerminalNumber=" + userInfo.getTerminalNumber()
+ "&apifunction=" + "GetAppUpdate";
httpConnect.sendPostRequest_appupdate(AppData.AppUpdateURL, data, new ConnectionListener() {
public void onRequestFailure(Object title, Object message) {
System.out.println("==>GetUpdateApp Failure\nTitle:"
+ (String) title
+ "\n Failure Message" + (String) message);
showMessageDialog((String) title, (String) message, new SettingsForm("Settings", parent), 2000);
}
public void onRequestSuccess(Object httpResponse) {
try {
System.out.println("==>On Success--of Update App");
String response = (String) httpResponse;
System.out.println("==>Login Form--Update App \nResponse:" + response);
JSONObject jsonObject = new JSONObject(response);
int responseCode = Integer.parseInt(jsonObject.getString("ResponseCode"));
switch (responseCode) {
case 000: {
String latestbuild = jsonObject.getString("LatestBuild");
String latestversion = jsonObject.getString("LatestVersion");
String downloadURL = jsonObject.getString("DownloadURL");
if (latestversion != null) {
if (!latestversion.equals(AppData.currentversion) || !latestbuild.equals(AppData.currentBuild)) {
if (Integer.parseInt(latestbuild) > Integer.parseInt(AppData.currentBuild)) {
System.out.println("Download URL--" + downloadURL);
// parent.platformRequest(downloadURL);
System.out.println("platform request boolean variable returns---"+ parent.platformRequest(downloadURL));
parent.platformRequest(downloadURL);
parent.destroyApp(true);
} else {
System.out.println("Incomapatible types");
showMessageDialog("Alert", "No new updates available", new SettingsForm("Settings", parent),2000);
}
} else {
System.out.println("App Version Number is same,No New Build Available");
showMessageDialog("Alert", "Application is already upto date", new SettingsForm("Settings", parent),2000);
}
} else {
System.out.println("App version not available on server");
showMessageDialog("Alert", "No new updates available", new SettingsForm("Settings", parent),2000);

If any 1 has any idea regarding Replacing App in J2ME then please Help me. Thanks a lot in Advance.

Shoutcast radio with J2ME

I have my application playing the radio stream which is shoutcast streaming. I have searched on the internet for 2 days but my application stills can't play this url. I don't know how to solve this.
This is my sample source code.
String url1 = "http://203.150.224.142:8003/;
HttpConnection con= (HttpConnection)Connector.open(url1);
InputStream is = con.openInputStream();
player = Manager.createPlayer(is, "audio/mpeg");
player.realize();
player.prefetch();
player.start();
I have used this code in production, it should work for you also.
HttpConnection conn = (HttpConnection) Connector.open(music.getTrack_url() + "?streamable=true", Connector.READ_WRITE);
if (conn.getResponseCode() == HttpConnection.HTTP_OK) {
is = conn.openInputStream();
player = Manager.createPlayer(is, "audio/mp3");
player.addPlayerListener(thisObj);
player.realize();
player.prefetch();
player.start();
}
Try This.
public void loadShoutcast(String url)
{
StreamConnection connection = null;
int BUFFER_SIZE = 1024;
DataOutputStream dos_ = null;
OutputStream os_ = null;
try
{
System.out.println("opening connection " + url);
//Shoutcast URL
connection = (StreamConnection) Connector.open(url);
os_ = connection.openOutputStream();
dos_ = new DataOutputStream(os_);
// send the HTTP request
String req = "GET / HTTP/1.1\r\nUser-Agent: Profile/MIDP-1.0 Configuration/CLDC-1.0\r\n\r\n";
dos_.write(req.getBytes());
is = null;
is = connection.openInputStream();
long byteDone = 0;
int byteCount;
byte[] buffer = new byte[BUFFER_SIZE];
//Connection to file where you want to save the content of shoutcast radio
//It can be skipped in case you dont want to save the contents
out = tempFilecon.openDataOutputStream();
System.out.println("starting download");
while (byteCount = is.read(buffer)) >= 0)
{
out.write(buffer, 0, byteCount);
byteDone += byteCount;
done += byteCount;
}
return;
}
catch (InterruptedIOException e)
{
System.out.println("InterruptedIOException 1" + e.getMessage());
return;
}
catch (Exception e)
{
System.out.println("ERROR - 51 " + e.getMessage());
return;
}
finally
{
if (dos_ != null)
{
dos_.close();
dos_ = null;
}
if (os_ != null)
{
os_.close();
os_ = null;
}
if (is != null)
{
is.close();
is = null;
}
if (out != null)
{
out.close();
out = null;
}
System.out.println("closing connection");
if (connection != null)
{
connection.close();
connection = null;
}
}
// return false;

Blackberry - How to consume wcf rest services

Recently i have started working on consuming wcf rest webservices in blackberry.
I have used the below two codes:

}
but with this code i am unable to obtain response as what the above wcf web service return
which is({"UserRegistrationResult":[{"OutputCode":"2","OutputDescription":"UserName Already Exists."}]})
Can anybody help me regarding its parsing in blackberry client end.
2.And the another code which i used is:
public class KSoapDemo extends MainScreen
{
private EditField userNametxt;
private PasswordEditField passwordTxt;
private ButtonField loginBtn;
String Username;
String Password;
public KSoapDemo()
{
userNametxt = new EditField("User Name : ", "hsharma#seasiaconsulting.com");
passwordTxt = new PasswordEditField("Password : ", "mind#123");
loginBtn = new ButtonField("Login");
add(userNametxt);
add(passwordTxt);
add(loginBtn);
loginBtn.setChangeListener(new FieldChangeListener()
{
public void fieldChanged(Field field, int context)
