Blackberry Push Integration Client Sample Code - blackberry

I need a sample application code for push integration in my blackberry application. I have registered my application for the push credentials and have received them.
please help,
Kind Regards,

Vaadin upload with PipedInputStream & PipedOutputStream example

I just started learning Vaadin 8 and my first example is Upload button. I was stuck with an issue where I could not solve the problem for many hours and hours.
Here it is,
I am returning PipedOutputStream in the receiveUpload method,
Here is the code for receiveUpload method,
public OutputStream receiveUpload(String filename, String mimeType) {
this.fileName = filename;
this.mimeType = mimeType;
try {
pipedOutputStream = new PipedOutputStream();
pipedInputStream = new PipedInputStream(pipedOutputStream);
if (filename == null || filename.trim().length() == 0) {
upload.interruptUpload();
} else {
}
} catch (Exception e) {
e.printStackTrace();
}
return pipedOutputStream;
}
In the uploadSucceeded method, I need to take the pipedinputstream and send it another method to load the stream into the database
public void uploadSucceeded(SucceededEvent event) {
try {
fileUploadOperation.upload(pipedInputStream); --> I need to push all the stream data in one go into a method to generate a file at the business layer
} catch (Exception e) {
e.printStackTrace();
}
}
When I was running the application, it hangs out for a long time and I could not figure out where it is. Later I could notice that both piped input and piped output streams should be created in separate threads or at least one of them in a separate thread but don't know how to handle it.
Any help

The problem in your example is that you need to do the actual file handling in a separate thread. The Viritin add-on contains a component called UploadFileHandler that simplifies this kind of usage a lot. It will provide you InputStream to consume. The integration test for the component contains this kind of usage example.
Also, my recent blog entry about the subject might help.

Blackberry java show recieved push message

After referring tons of tutorials finally somehow I managed to develop java push client for Blackberry OS 7.0 (registering in RIM and server side are completely ok, this is the server script). Now the program running on the device and when new push massage revived there is a little arrow blinking on right up corner of the device, but I haven't that much knowledge to show that message in a label field or any other UI component. Please tell me how to show the revived push message in a screen. I'm beginner in programming so I haven't that much of knowledge need your help. Here I post all the codes that I have used.

What I have to add for the main screen to show in coming message ??
Thank you in advance.

BlackBerry Push Notifications , OS < 7.X

I am working on developing a BB OS<7.X application, that implements push notifications. I finally ended up with some working code that is able to receive push.
However, the push notifications DONT work the first time i deploy the application on the phone. If i try to send a push on the device, after i just deployed it, when i send the push from my server, i can see on the right up corner of my device a little arrow loading , but no push message is displayed on the screen.
If i restart the device, the push notifications work properly!! Now whenever i send a push, i see the little arrow again on up right screen and the push message displayed corrected.
The code looks like this(the parts i consider important):
MyApp.java
public class MyApp extends UiApplication
{
public static void main(String[] args)
{
//every time we start the application we register to BIS for push
if (args.length > 0 && args[0].equals("BlackBerryCity")) {
System.out.println("!!!!!!!!!!!!!!I am inside if");
//registering for push
push_main.registerBpas();
MyApp app = new MyApp();
app.enterEventDispatcher();
}
//every time we restart the phone , we call this background process that is responsible for listening for push
else {
System.out.println("!!!!!!!!!!!!!!I am inside else");
//should put the background classes for listening to pushed msgs :D
BackgroundApplication backApp=new BackgroundApplication();
backApp.setupBackgroundApplication();
backApp.enterEventDispatcher();
}
}

On the main class , MyApp.java , as you can see everytime the application is launched, i register for push. Every time the device restarts, i start a background process to listen for push. Or at least, this is what i believe i am doing here.
Why should i do that?
I thought that by registering for push, the background listener would somehow start too... But i guess it doesn't.. That's why probably when i restart the phone, this code is executed and the push starts coming in.
How could i fix this problem so that i could start the background listener:
the first time the app is deployed
every time i restart the device
but NOT on every launch of the app.

Suspended (exception IlegalStateException) blackberry 6.0

Following is the code which is showing the above exception on debugging :
Firstly I am trying to call a class HTTPConnection from the below menu item.
protected MenuItem _SelectDealerItem = new MenuItem("Select Dealer",100,10)

};
In HTTPConnection Class I am checking the connection type and calling another Class TSelectDealerScreen:
public class HTTPConnection {
ConnectionFactory _factory = new ConnectionFactory();
public HTTPConnection()
{
int[] _intTransports = {
TransportInfo.TRANSPORT_TCP_WIFI,
TransportInfo.TRANSPORT_WAP2,

};
for(int i=0;i<_intTransports.length;i++)
{
int transport = _intTransports[i];
if(!TransportInfo.isTransportTypeAvailable(transport)||!TransportInfo.hasSufficientCoverage(transport))
{
Arrays.removeAt(_intTransports,i);
}
}
TcpCellularOptions tcpOptions = new TcpCellularOptions();
if(!TcpCellularOptions.isDefaultAPNSet())
{
tcpOptions.setApn("My APN");
tcpOptions.setTunnelAuthUsername("user");
tcpOptions.setTunnelAuthPassword("password");
}
if(_intTransports.length>0)
{
_factory.setPreferredTransportTypes(_intTransports);
}
_factory.setTransportTypeOptions(TransportInfo.TRANSPORT_TCP_CELLULAR, tcpOptions);
_factory.setAttemptsLimit(5);
Thread t = new Thread(new Runnable()
{
public void run()

displayContent(c);
}
}
});
t.start();
}
private void displayContent(final Connection conn)
{
UiApplication.getUiApplication().pushScreen(new TSelectDealerScreen(conn));
}
}
In TSelectDealerScreen class i am simply trying to read the stream, but it is showing illegal state exception whenever i try to debug, I am not much familiar to blackberry programming, kindly advice.

public void showContents(final String result)
{
UiApplication.getUiApplication().invokeLater(new Runnable()

}
}
In your HTTPConnection class, you do:
Thread t = new Thread(new Runnable()
{
public void run()
{
ConnectionDescriptor cd = _factory.getConnection("http://excellentrealtors.info/Smart-Trace/get_dealer.php");
if(cd!=null)
{
Connection c = cd.getConnection();
displayContent(c);
}
}
});
t.start();
That runs everything inside run() on a background thread. But, inside displayContent(c), you do:
UiApplication.getUiApplication().pushScreen(new TSelectDealerScreen(conn));
which is a UI operation.
Trying to modify the UI from a background thread normally causes an IllegalStateException.
I believe you just need to wrap the call to pushScreen() with this:
private void displayContent(final Connection conn) {
final UiApplication app = UiApplication.getUiApplication();
app.invokeLater(new Runnable() {
public void run() {
// this code is run on the UI thread
app.pushScreen(new TSelectDealerScreen(conn));
}
});
}
Also, if you're an Android developer, and you want help doing normal background/UI thread stuff, you might check out this other answer I wrote on "porting" AsyncTask to BlackBerry Java

In this project, I checked Auto-run on startup so that this background app listener will run all the time and set the start tier to 7 in the BB App Descriptor.
However, it cannot display the popup Dialog, but I can see the device has received the push notification.
After the dialog popup and user click OK will start the OrientalDailyBB project and display the particular MainScreen.
FYI: The listener priority is higher than the OrientalDailyBB project because it is a background application. So when I install OrientalDailyBB, it will install this listener too. It happened because this listener is not in the OrientalDailyBB project folder, but is in a different folder. I did separate them to avoid the background application being terminated when the user quits from OrientalDailyBB.
I believe that this is a threading problem. pushGlobalScreen is a message you could try to use with invokeLater.
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
ui.pushGlobalScreen(screen, 1, UiEngine.GLOBAL_QUEUE);
}
});
you could try to push the application to the foreground too.
