Java 蓝牙不在Windows PC中运行

嗨，我写了一个关于蓝牙的java应用程序 当我在eclipse控制台中运行时，它运行正常 但当我在命令行中运行时，会出现错误 导入javax.bluetooth.BluetoothStateException； 导入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");
}

}

出错

C:\Users\HUNGSON\workspace\Java_Test\bin>java main
Exception in thread "main" java.lang.NoClassDefFoundError: main

请帮帮我

您的目录结构是什么样的？你的问题甚至比蓝牙还严重。你的Main.class是否在一个包中？试着用java mypackage.Main调用它“试着用java mypackage.Main调用它”当我尝试java javabluetooth.Main时你可以说得更清楚，但它有错误“错误：找不到或加载主类javabluetooth.Main“请帮助我！！！这是我的全部项目
