BlueCove library bluecove not available - Error using Bluecove/Java

Question

How do I install Bluecove in Ubuntu 11/Eclipse IDE?

As far as i was aware, all I had to do was add the bluecove.jar and bluecove-gpl.jar to the Build-Path of the project within Eclipse.

I'm using some sample Bluecove code found here: http://bluecove.sourceforge.net/bluecove/apidocs/overview-summary.html#DeviceDiscovery

When I compile it, I'm getting an error: Native Library bluecove_x64 not available Exception in thread "main" javax.bluetooth.BluetoothStateException: BlueCove library bluecove not available

Obviously, my Bluetooth USB dongle is plugged in when I do this... I definitely have BlueZ protocol stack installed.

What am I doing wrong? Is Bluecove supported by 64-bit Linux? I've also been trying to get it installed on a CentOS 5.5 machine as well, but with no luck.

Any help would be greatly appreciated. Thank-you
