Hi,
some time ago I asked for a TCP listener on Blackberry (TCP Listener). This Topic was closed, so I have to start a new one.

The last Post is about pushing some data over http to the BB. The Example link sounds interesting, but I have no idea about the parameters http://server:port/push?DESTINATION={dest}&PORT=7874&

Are there any changes for the BES?
Which port do I have to use for Index of / ?
Which value should {dest} have, the pin of the device?

Maybe someone can answer my questions and help me

thanks

I don't know what you are asking here.

Which port do I have to use for Index of / ?

This is the port of the MDS server associated with the BES, usually 8080 IIRC

Which value should {dest} have, the pin of the device?

This is the PIN of the device or the email address associated with the device on the BES.

Maybe someone can answer my questions and help me

thanks

I will try it. Thanks for your help.

If I have more questions I will come back

Hi,
OK, it works
But I still have one problem and one question left:

First the problem: I have used your Code from the other Post. That works fine, but the StreamConnection is always null. Maybe it can be solved with my other question:

I want to push some Data onto my BB, so that I get a String in my Application. What do I have to push to the Device? Are there more Parameters (i couldn't find some more) or which Headers do I have to use?

Thanks again

Who's code, from which post?

[hibbert]

I have used the Example of my Last Post (TCP Listener).

I start the push within the internet explorer or with a simple httprequest from VB.net.

Hi,
ok, with this function i can receive Data on my BB.

/**
     * The listener thread, listens for push data from the MDS.
     * it is usually better to do TCP communications in a separate thread
     */
    static class ListenerThread extends Thread
    {
        private boolean stopThread;
        private StreamConnectionNotifier notify;
        private StreamConnection stream;
        private InputStream input;
        
        ListenerThread()
        {
            super();
            stopThread = false;
            notify = null;
            stream = null;
            input = null;
        }
        
        public void stop()
        {
            synchronized(this)
            {
                stopThread = true;  // set the flag to stop the thread.
                
                // if the stream is null (no input happening) but notify isn't

                if (stream == null && notify != null)
                {
                    try
                    {
                        notify.close(); // close the listening socket
                    }
                    catch (Exception e)
                    {
                        System.err.println(e.toString());
                    }
                }
            }
            
            try
            {
                join(); // wait until the thread completes.
            }
            catch (Exception e) {}
            
        }
        
        public void run()
        {
            synchronized(this)
            {
                // this sleep shouldn't be necessary, but it helps to stagger 
                // threads if you start lots in an auto run application
                try
                {
                    sleep(1000L);
                }
                catch (Exception e)
                {
                }
                
                System.out.println("background thread -- running");
            }
            
            try
            {
                // Create a stream connection notifier on http protocol (for push)
                // and the port we want to use.
                notify = (StreamConnectionNotifier)Connector.open("http://:555");
                
                
                
                while (!stopThread)
                {
                    // block until data is received
                    stream = notify.acceptAndOpen();

                    synchronized(this)
                    {
                        if (stopThread)
                            break;
                        input = stream.openInputStream();
                    }
                    
                    someFunctionToProcess(input);
                    stream.close();
                    stream = null;
                    input = null;
                }
            }
            catch (Exception e)
            {
                System.err.println(e.toString());
            }
        }
    }

Now I have tried to send back a String, like this:

try {
                    OutputStream os = stream.openOutputStream();
                    byte[] theByteArray = ((String)"ACK").getBytes("UTF-8");
                    os.write(theByteArray);
                    os.flush();
                    os.close();
                    os = null;
                } catch (Exception ex) {
                    System.out.println(ex.toString());
                }

How Can I send back a Message to the sender, e.g. an "ACK"?

thanks hibbert
