heap size -xms and -xmx definition on a per-app basis in manifest file?

With JNLP it's even simpler - just tell users to click on link (with jnlp file) on your web page. Application will be downloaded by Java Web Start and then started.
There is no need to find place on user's filesystem where to store appname.jar and then clicking on it, or creating shortcut on desktop.

BTW, what are benefits of having single jar file? Why do you believe that this is the right way?
