Has anyone ever faced any prob connect to a bluetooth service using j2me?

[phpuser123]

I 've been trying to connect to a bluetooth service using j2me but I am getting a null exception..The client is able to identify devices in the nearby regions but not being able to connect to their service.I am pasting my codes and would be highly obliged if any1 could tell me the reason and if the codes are correct..

 
//Server
public  void startServer() {
 
        System.out.println("server is running...");
                UUID uuid = new UUID("1101", true);
                String connectionString = "btspp://localhost:" + uuid +";name=Server";
        try {
            // create a server connection
            StreamConnectionNotifier notifier =(StreamConnectionNotifier) Connector.open(connectionString);
            // accept client connections
            StreamConnection connection = notifier.acceptAndOpen();
 
                    LocalDevice localDevice = LocalDevice.getLocalDevice();
                    stringItem.setText(localDevice.getFriendlyName()+" : "+localDevice.getBluetoothAddress());
                    System.out.println("Address: "+localDevice.getBluetoothAddress());
 
                    System.out.println("Name: "+localDevice.getFriendlyName());
 
            // prepare to send/receive data
            byte buffer[] = new byte[100];
            String msg = "hello there, client";
            InputStream is = connection.openInputStream();
            OutputStream os = connection.openOutputStream();
            // send data to the client
            os.write(msg.getBytes());
            // read data from client
            is.read(buffer);
                    int len = is.available();
 
                    stringItem.setText(Integer.toString(len));
            connection.close();
        } catch(IOException e) {
          e.printStackTrace();
        }
 
    }
 
 
 
 
 
//Client
private void deServiceSearch(RemoteDevice device) {
        //int[] attr={10203040607040A1B1C1DE100};
    System.out.println("TEst4..");
        setError("2");
        UUID[] uuids = new UUID[1];
        uuids[0] = new UUID(1101);
 
 
        try {
 
            System.out.println("TEst6..");
 
            UUID[] uuidSet = new UUID[1];
 
            uuidSet[0]=new UUID("1101",false);
 
            System.out.println("\nSearching for service...");
            setError("3");
            agent.searchServices(null,uuidSet,device,this);
 
        } catch (BluetoothStateException ex) {
            setError("4");
        }
    }

I think you have a mistake here :

// prepare to send/receive data
byte buffer[] = new byte[100];
