BT and Java - Btl2Cap Connection (Mobile phone and Digital Pen)

Question

Hi!
First a short Introduction:
For a project I have to stream data from Maxell Penit DP201(4.1) to a mobile device (over a midlet). Data Connection is built up over Bluetooth.
My Questions are: Is btl2cap the right method for connecting digital pen and mobile phone?
If yes, is the btl2cap string correct?
The pens device adress is 00-07-CF-56-05-5D
Does anyone know a sample application like this I want to program?
Structure;
package /
Midlet
Class extending thread
Here's the code:
public void run() {
    //Bluetooth
    //String connString = "btspp://0007808303AA:1;master=false";
    String connString = "btl2cap://localhost:0007cf56055d;ReceiveMTU=512;TransmitMTU=512";
    System.out.println(connString);
    try {
            LocalDevice local = LocalDevice.getLocalDevice( ) ;
// build ServiceRecord
            local.setDiscoverable(DiscoveryAgent.GIAC);
L2CAPConnectionNotifier service = (L2CAPConnectionNotifier)
Connector.open(connString);
ServiceRecord sr = local.getRecord(service);
// accept Connection
L2CAPConnection connection = (L2CAPConnection ) service.acceptAndOpen( );
        } catch (Exception e) {
            e.printStackTrace();
        }Thanks to all who can help me to reach the next step in my project.
Best regards

Hi,
The reason for the compilation error is that the IDE is not able to find the jar file where bluetooth api is packed. try to put the jar file in lib directory of the project. Some IDE generates class files even though there are some compilation errors in java file.
So it is better to resolve compilation errors before putting it in the device.
The reason why the app freezes in the device is that you have not used a seperate thread to do the inquiry, try to use a thread where the inquiry will be done so that the apps main thread will respond to the user input.
Hope this help you.
