if it runs in Eclipse, there is a valid run configuration.  Make sure the one you choose when making the .jar file is the same one you use to run the code in Eclipse.

yeah, but the class is not showing in the launch configuration. 

I created this jar file, but when I run it in command prompt, it says this

no main manifest attribute, in Lab8.jar

what should i do?

are you sure you chose "runnable jar file" as opposed to just "jar file" in the first dialog box?

yeah, i'm choosing runnable jar file.

In my class I have this main method

--------------------

public static void maint(String[] args) {

launch(args);

}

=========

is it correct?

yes, that looks right, assuming maint is a typo for main.  Ask Sumanth for help in the lab today
