What I've done so far:
I wanted to add facebook support to my native Java application (Java Web Start application). To get a valid access token for a new user, I forward the user to a web page where he can do the authentication (I don't think there is way doing the authentication directly from the native Java application because I don't use SWT to embed a browser). I'm saving the access token and now I have access from my native Java application to facebook.
The problem:
When the access token expires or becomes invalid for any reason, I have to repeat the whole proces to get a new, valid token. Isn't there a way to get a new access token silently, without user interaction?
Thanks in advance!
