BluetoothStateException:BluetoothStack not detected

[Budkudyba]

hi all,
I am starting with the RemoteDeviceDiscovery code example. I'm kinda
new to java, but when i compile with netbeans i get this list. I've
looked and tried some remedies regarding detecting the bluetooth
stack.

Exception in thread "main" javax.bluetooth.BluetoothStateException:
BluetoothStack not detected
at com.intel.bluetooth.BlueCoveImpl.detectStack
(BlueCoveImpl.java:476)
at com.intel.bluetooth.BlueCoveImpl.access$500

at blue.RemoteDeviceDiscovery.main(RemoteDeviceDiscovery.java:
48)

I am using windows 7 beta 7000. I can see the device and can pair with
my wiimote using the app that came with my iogear bluetooth (gbu421).
It uses the broadcom/widcomm stack.

I've also tried the Bluecove tester and got the same results.

19:19:15 Stated app

19:19:20 e.BluetoothStack not detected
19:19:20 e.start error BluetoothStateException:BluetoothStack not
detected

I've also run the Remote discovery with XP and everything works like a
charm.

Thanks in advance for any help or ideas.

Enable debug and see the error messages.
Are you using BlueCove version  2.1?

Thanks for the prompt response.
yes, I am using 2.1.
I enabled debug and got this...

After looking up 10050, I figured it might be the windows Firewall
(and defender), but when disabled there was no change.
I have a feeling this is a Win 7 beta 7000 problem(because of it
detecting and running with Xp), but let me know if you still have any
suggestions or need more info.
My widcomm driver is 5.1.0.4500

Thanks

I was thinking that on Vista widcomm required driver starting from version 6.

I don't see in the log attempt to load widcomm interface dll: blucove.dll

Try adding -Dbluecove.stack=widcomm

This will try to find: wbtapi.dll  on your system.
The wbtapi.dll comes with widcomm stack.
