Probably because the working directory is not where you expect so does not contain the 'classes' directory or the manifest file. You can define the working directory by using the exec() command that has 3 arguments (setting the second to null) or you can use the full paths to the files/directories.
If you have no done so then you should certainly read

Edit: I just looked again at your post - 'classes.class' seems a funny name for your class file or for the root directory for your class files. Have you tested the 'jar' command from the command line? if not then do so.
