蓝牙无法在窗口PC中运行

Question

你好我写了一个关于蓝牙的java应用程序 当我在eclipse控制台中运行它运行正常 但是当我在命令行中运行它会发生错误 import javax.bluetooth.BluetoothStateException; import javax.bluetooth.LocalDevice;

public class main {

/**
 * @param args
 * @throws BluetoothStateException 
 */
public static void main(String[] args) throws BluetoothStateException {
    // TODO Auto-generated method stub
    LocalDevice local=null;
    local = LocalDevice.getLocalDevice();
    System.out.printf("this is some text");
}

}

发生错误

C:\Users\HUNGSON\workspace\Java_Test\bin>java main
