Why does JavaFX deployment rely on javascript and connecting to sun servers

Question

I understand that there's a way to deploy javafx applets and jnlp offline by downloading the required files from sun's website.
But normally, it seems that a connection to sun servers must be made for anything to run and javascript has to be enabled to use applets.
Why is connecting to sun servers necessary? especially, when the client already has the javafx runtime.
What if the client loses internet connection or disables javascript, how can one run the JavaFX application/applet then?

Answer 1

it seems that a connection to sun servers must be made for anything to runYes, it is (unfortunately) in the license, which doesn't allow to distribute the JavaFX software.
See also two (at least) related threads: [Interaction between Swing and JavaFX?|http://forums.sun.com/thread.jspa?forumID=932&threadID=5362457] and [Distribution JavaFX application without web start|http://forums.sun.com/thread.jspa?threadID=5367483] with a kind of official answer.
javascript has to be enabled to use appletsIt is a quite common requirement, people ready to run Java shouldn't be afraid to enable JavaScript... :-)
Why is connecting to sun servers necessary?I suppose it is to ensure the latest runtime is used, for a better experience...
What if the client loses internet connection or disables javascript, how can one run the JavaFX application/applet then?Well, if they don't have an Internet connection, I suppose they can't reach the page where the applet is... :-)
Not necessarily true, the applet can be on a network and the Internet access can be deactivated.
I haven't tried, but I think if the runtime is in cache, the applet can be run. Although the applet loading code or the JNLP can attempt to check for a new version, I don't know what happen when they cannot.
