What is executable JAR file?
An executable JAR file invoke the application main class when the user performs double click. The same can be runnable by java -jar <jarfilename> command.
How to create executable JAR file by manually?
Create manifest.MF to point your main class.
Ex: Main-Class: com.epractizelabs.librarymanager.LibraryMain
Run the JAR command
jar -cvmf Manifest.MF yourapplicationname.jar *.*

Ooh, I think there is misunderstand here,
that I mean executable file, is the file or application that can be run only by click or double click,
not, I need to go to command prompt and I must write:
jar -jar <jarfilename>
or I must write or run something. (+_+)
just like an installer. . . .
I agree. Here's the link:
