How to run a jar file

[KALIDA]

I created a small jar file called HelloWorld using Matlab Java Builder tool. But although creating the jar file so good, I could not run it. What is the exact command to use? On internet, it said to use this:

% java -classpath D:\Matlab\toolbox\javabuilder\jar\javabuilder.jar;hello.jar examples.hello

but this does not work!

It gave me the error as:

'%' is not recognized as internal or external command, operable program or batch file.

If I remove the %, the error is:

Failed to load Main-Class manifest attribute from D:\Matlab\toolbox\javabuilder\jar\hello.jar

Can you help me please?

Try the following from MS-DOS console:

java-jar hello. jar

Thank you for your response, DOS returns an error of Manifest:

Failed to load Main-Class manifest attribute from 
hello. jar

This is the event in question (open with Eclipse):

Manifest-Version: 1.0
Created-By: 1.6.0_16 (Sun Microsystems Inc.)

you can extract the contents of your file with the command hello.jar

jar xvf hello.jar

Your manifest must be of type

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

Hello is the main class (containing the method "main")
