Hi,

I make an application in java ME (client) that connects to a PC application (server) using OBEX protocol. Connection goes well but I don't understand why I can use the stream to send JUST one message
frmo the client and after that I must close the stream to see the message at the server.
I have these codes:
SERVER (PC)

public void startServer() throws IOException{
             LocalDevice.getLocalDevice().setDiscoverable(DiscoveryAgent.GIAC);

        

            serverConnection = (SessionNotifier) Connector.open("btgoep://localhost:"
                + serverUUID + ";name=ObexExample");


        
            handler = new RequestHandler();
            System.out.println("waiting for clients...");
            serverConnection.acceptAndOpen(handler);
            System.out.println("Received OBEX connection ");
        
        }


String serverUUID = "123";
    Operation operation;
    DataInputStream dis;
    InputStream is;


    private class RequestHandler extends ServerRequestHandler {

        @Override
        public int onPut(Operation op) {
            try {
                HeaderSet hs = op.getReceivedHeaders();
                String name = (String) hs.getHeader(HeaderSet.NAME);
                if (name != null) {
                    System.out.println("put name:" + name);
                }

             
                dis = op.openDataInputStream();
                int a = 0;
//just show me incoming mesages as they arrive
                while((a=dis.readInt())!=-1000);// I RECEIVE THE MESSAGE HERE ONLY ONE TIME
                   System.out.println(a);


                return ResponseCodes.OBEX_HTTP_OK;
            } catch (IOException e) {
                e.printStackTrace();
                return ResponseCodes.OBEX_HTTP_UNAVAILABLE;
            }
        }
    }

CLIENT (Mobile Phone)

public void startObexClient(){
        
        if (serverURL == null) {
            String[] searchArgs = null;
            try {
               
                 searchArgs = new String[] { "123" };
                 System.out.println(LocalDevice.getLocalDevice().getBluetoothAddress());
                ServicesSearch.main(searchArgs);
            } catch (IOException ex) {
                ex.printStackTrace();
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
            if (ServicesSearch.serviceFound.size() == 0) {
                System.out.println("OBEX service not found");
                return;
            }
            // Select the first service found
            serverURL = (String)ServicesSearch.serviceFound.elementAt(0);
        }

        System.out.println("Connecting to " + serverURL);

      
        
            try {
                clientSession = (ClientSession) Connector.open(serverURL);
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        HeaderSet hsConnectReply = null;
            try {
                hsConnectReply = clientSession.connect(null);
            } catch (IOException ex) {
                ex.printStackTrace();
            }
            try {
                if (hsConnectReply.getResponseCode() != ResponseCodes.OBEX_HTTP_OK) {
                    System.out.println("Failed to connect");
                    return;
                }
            } catch (IOException ex) {
                ex.printStackTrace();
            }

        HeaderSet hsOperation = clientSession.createHeaderSet();
        hsOperation.setHeader(HeaderSet.NAME, "Hello.txt");
        hsOperation.setHeader(HeaderSet.TYPE, "text");

        //Create PUT Operation
        //Operation putOperation = null;
            try {
                putOperation = clientSession.put(hsOperation);
            } catch (IOException ex) {
                ex.printStackTrace();
            }
}

Now... from the client I send messages like this:

try {
                        DataOutputStream    das = putOperation.openDataOutputStream();
                        } catch (IOException ex) {
                            ex.printStackTrace();
                        }


                        try {
                            das.writeInt(12);
                            das.close();
                        } catch (IOException ex) {
                            ex.printStackTrace();
                        }

it only works ONE time :(. Why? I also tried to open the stream just one time and after that just do:

das.writeInt(12);
das.flush();//just as a Socket object...

but nothing happens until I close the stream :(...

my question is: HOW CAN I SEND MESSAGES CONTINOUSLY? (using the same stream)

hi friend i am also doing the same project i am connecting with the mobile from pc but i did,t know how to send a message from pc to mobile.because ACCEPTANDOPEN() FUNCTION IS NOT WORKING.THERE R FEW DAYS TO COMPLETE MY PROJECT. SNIP

THANKS IN ADVANCE
