You need to modify the MANIFEST.MF file present in the META-INF directory and give the name of the class containing the main method.
Check this tutorial

Alternatively, You can Run it using a .bat file. Type in a notepad:



The save as all files with a .bat extension in the same folder as the .jar file. Then double click the .bat file......Just a thought
