Creating jar from command prompt giving error

Question

I have tried the example as the same as written as answer from this link'How to create a .jar file using the terminal' to create a jar file from command prompt. But I am getting an error 'no main manifest attribute , in Helloworld.jar'. What will be the problem? Please help.I done the same as explained in that method.

@wrongAnswer I am building my project from simple way no IDEs used!! — androidGenX, Oct 17 '14 at 14:02
I strongly suspect you *haven't* done exactly the same thing. What does your manifest file look like before jarring? If you extract the jar file, what does the manifest from it look like? — Jon Skeet, Oct 17 '14 at 14:02
Does the class HelloWorld exist in the source you're compiling? — C. Ross, Oct 17 '14 at 14:03
And has that successfully been included in the jar file? (This is all information that should be in your question.) — Jon Skeet, Oct 17 '14 at 14:03
@JonSkeet my question is when I do the step 'java -jar HelloWorld.jar' I am getting 'no main manifest attribute , in Helloworld.jar', instead of printing my result — androidGenX, Oct 17 '14 at 14:06
and the manifest file is ended by a new line? This is important. — Plux, Oct 17 '14 at 14:10
We're *trying* to help, but you're not giving us the information that we've asked for. — Jon Skeet, Oct 17 '14 at 14:14
try editing your question tell the procedure how you created the jar and necessary information like if it contains some package definition if it contains some other class definition — SparkOn, Oct 17 '14 at 15:07
