jar文件未执行

Question

I'm trying to execute jar file of netbeans swing small project. The file isn't executing. I need to make it work by double clicking on the jar file that is located in:

C:\Users\armyTik\Documents\NetBeansProjects\Notepad\dist\Notepad.jar

extra details:

properties -> Build -> Packaging -> "Build JAR after compiling" and "Copy Dependent Libraries" are checked.

properties -> run -> Main class: "notepad.NotepadComponent"

In the cmd, by manually executing the jar file I get the following error:

cd C:\Users\armyTik\Documents\NetBeansProjects\Notepad\dist
java -jar Notepad.jar
"Error: Could not find or load main class notepad.Notepad"

What should I do, specifically?

---

EDIT:

I extracted the jar file and got:

META-INF/MANIFEST.MF
notepad/FileManager.class
notepad/icon.gif
notepad/NotepadComponent$1.class
notepad/NotepadComponent$2.class
notepad/NotepadComponent$3.class
notepad/NotepadComponent$4.class
notepad/NotepadComponent$5.class
notepad/NotepadComponent$6.class
notepad/NotepadComponent$7.class
notepad/NotepadComponent.class
notepad/Thumbs.db

META-INF/MANIFEST.MF content:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.4
Created-By: 1.8.0_102-b14 (Oracle Corporation)
Class-Path: 
X-COMMENT: Main-Class will be added automatically by build
Main-Class: notepad.NotepadComponent

Update2:

I got new exception while trying to open the jar from the cmd:

While opening the project from netbeans, the icon is shown with no exception. *****When I remove the icons , The jar is working! but I need to keep the icons in the application.

This is because your classpath is not correct. Try it like this:

java -cp "<PATH>/Notepad.jar" notepad.Notepad

If this does not work then unpack the jar file and confirm the package and class name is correct, Print CLASSPATH env variable or check java and javac versions.
