Login with Facebook in java From Desktop Removing Permission box

Question

After a lot of doing searching of login with facebook from desktop application i made my my self using DJ Native swing browser.

but still i have one problem that i need to change something.

I am using login with facebook using Enabled Browser Swing. When I logged into Facebook I am getting one permission box which is asking for user permission. but I don't want to show that box. is it possible to grant permission auto in Facebook.

I just want to remove this warning dialog and want to grant Permission auto so how could I do that?

any Suggestion is Welcomed.

Answer 1

Well i solved it by just removing some parameters like i make URL of

 public static String firstRequest = "https://graph.facebook.com/oauth/authorize?"
            + "client_id="
            + API_KEY
            + "&redirect_uri=http://www.facebook.com/connect/login_success.html&"
            + "scope=email,offline_access";

its just asking only once as i want :)

well here the example for the same.
