Let's say that all your project file's are in folder named MyApp

then

open command prompt
navigate to directory where MyApp is placed using cd
execute command jar cvf MyApp.jar MyApp

EDIT (To make this jar executable:)

create a file named MANIFEST.MF and put it in META-INF folder

META-INF/MANIFEST.MF

Manifest-Version: 1.0
Main-Class: com.somepackage.MyApp

OR you can simply use Launch4j to wrap up your program into an executable: http://launch4j.sourceforge.net/
