Windows command line Error(SOLVED),but how to add LWJGL?

[Doubstract]

I am trying to create a runnable jar file. I am using multiple classes and packages.

Windows 7 32-bit. jdk1.7.0_17. jre7.

I am using windows prompt, because i guess there is no other way to create runnable jar file with multiple classes. Right now i am getting this:
C:\Users\Admin\LudumDareDone\bin>java -jar "ludum.jar"
Error: Could not find or load main class Main

i have this manifest:
Manifest-Version: 1.0
Created-By: <Your info>
Main-Class: Main.java


i applied it with this command:
jar cfm ludum.jar manifest.mf


What i should do? Maybe there is other way to create runnable jar file with multiple classes? I searched answer in Google, but i cant find anything usefull, please give me direct links or answer.

IDEs have the option to generate a runnable jar from Your project.
Your current issue is that You need to define a fully qualified class name: "com.my.package.Main"
Class is the the class object, the structure You are using within Your program, as such "Main.java" is not what is needed in that location.

Sorry for stupid question, but i think i am doing something wrong here. What is fully qualified class name?
Currently, i have this:
MyJavaProject
----src
--------(default package)
------------Main.java

How fully qualified class name should look like?


EDIT:
i am using eclipse

Hi

Rather put that into your manifest:

Main-Class: Main

Whatever your IDE is, try to understand what happens under the hood.

[xsvenson]

Fully qualified class name consist of package name and class name. As in my previous post "com.my.package" is package name and "Main" is the class name.
Package translates 1:1 to the folder structure, so for the given package "com.my.package" the folder structure would be like this

Project
  |_ src
      |_ com
            |_ my
                 |_package
                     |_ Main.java

In Your example, You are not using package so Your fully qualified class name is the same as the simple form "Main"
http://en.wikipedia.org/wiki/Fully_qualified_name

Why package names ? It's a form of namespace. Imagine using 7 different libraries, non using packages and everyone having a "Main" class. How would You tell Your program, which one to use ?
That's why there are packages. All libraries and programs in java world are in packages. There are also other benefits

I just meant that ".java" has nothing to do in the manifest attribute "Main-Class".

[Damocles]

try a manifest:

----
Manifest-Version: 1.0
Class-Path: .
Main-Class: Main
----

using the manifest name

MANIFEST.MF
in the folder META-INF

Now i think i have another problem:

EDIT:
What i should do? Where is problem? Or maybe there is another way to create runnable jar file with multiple classes?

[Doubstract]

I think i finaly done that, but i tried simple program with pure java. I want to add lwjgl. How i should do that?

[gouessej]

It's explained here:
http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html

Class-Path: MyUtils.jar

Edit.: Don't forget to do something for the native libraries.
