Hi all,

To discover the devices using a J2SE program i am finding errors for it.

My code is as

Code:
System.out.println("Button for Discover Devices");
try
{
System.out.println("Try block entered");
LocalDevice localDevice = null;
localDevice = LocalDevice.getLocalDevice();
System.out.println("getLocalDevice");
discoveryAgent = localDevice.getDiscoveryAgent();
System.out.println("getDiscoveryAgent called");
updateStatus("[client:] LocalDevice properties: " +
localDevice.getFriendlyName() + " (" + localDevice.getBluetoothAddress() + ")");
updateStatus("[client:]Searching for Bluetooth devices in the vicinity...");
discoveryAgent.startInquiry(DiscoveryAgent.GIAC, this);
}
catch(Exception e)
{
e.printStackTrace();
}

When i run this program, i get the following error.

Button for Discover Devices
Try block entered

Can anyone pl tell me why is the getLocalDevice() method causing problems? I have included JSR-82 from Wireless Toolkit library also.

Also can anyone provide me with the code for transferring a file from PC(or laptop) to mobile through Bluetooth?

Is your Bluetooth on?

Hey maozet,

Thanks for the quick reply. Yes the bluetooth is on and still the same exception. Surprisingly, almost the same thing works on the mobile phone in a normal way. I feel it's something to do with some bluetooth configurations of a laptop, may be. Please let me know if you want any more info about code snippet or the exception.

Don't get surprised, me and vijusan are doing the project together.

Has the localdevice.getlocaldevice() got anything to do with the way a bluetooth has been configured? We are using a Bluetooth dongle connected through USB. I traced the program and encounters an error exactly on this statement

localDevice = LocalDevice.getLocalDevice();

We got the BluetoothStateExcption error. javax.bluetooth.BluetoothStateException: java.lang.NoClassDefFoundError: com/sun/kvem/jsr082/bluetooth/DiscoveryAgentImpl

If anyone has any ideas or suggestions then pl help. We r adding JSR82.jar externally through Configuring Buildpath in Eclipse imported from Sun Wireless Toolkit Library.

The same program with some minor changes made is running perfectly fine on the mobile.
