Answer 1

Use this link to add the name of the main-class to the manifest.

You may want to write a java program to browse a jar file and display the contents of the Manifest so that you can check that it is correct.

Answer 3

The Manifest is the file in an executable jar file that tells java which class to run on startup. Maybe your jar file isn't really an executable jar file? You can look in the jar with winzip. Finally, if you made the jar yourself, check the manifest for proper fomatting, it has a strict word wrapping that is enforced.
