Jar file problem

Hey guys, im having some trouble with making a jar file.

In the command line i type

jar cvfm MyApp.jar MyApp.mf *.class

and it makes the jar file for me, but when I try to run the file by typing:

java -jar MyApp.jar

i get an error saying

Failed to load Main-Class manifest attribute from

A1.jar

my manifest file looks like this:

Manifest-Version: 1.0

Main-Class: driver

any suggestions?
