You have a number of options. You can write batch file which incudes the "java -jar jarFile.jar" command. You could write a piece of naive code to do the same and create a .exe. Or you can tweak the OS to do something simmilar (associate .jar files wit ha more general batch file).

Create the archive and include the manifest addition with a command like this which archives two class files into an executable Foo.jar:
