求救：windows环境下无法运行JAR包下的class文件
F:\>java -cp MinaTest.jar com.sony.client.test.QzjTemp.class

Exception in thread "main" java.lang.NoClassDefFoundError: com/sany/client/test/

QzjTemp/class

Caused by: java.lang.ClassNotFoundException: com.sony.client.test.QzjTemp.class

Could not find the main class: com.sony.client.test.QzjTemp.class. Program will

exit.

该class文件运行一个Main函数，弹出对话框
String path=JOptionPane.showInputDialog(null,"请输入路径:");
File file = new File(path);
[解决办法]
试试java -cp MinaTest.jar com.sony.client.test.QzjTemp
[解决办法]
执行java程序，不需要加.class的
改成
java -cp MinaTest.jar com.sony.client.test.QzjTemp
