Solved Cracked and Premium test?

My english is not so good, i know
Hi,
I want to create a Plugin with it you can only join with a cracked account if the name is not reserved by a premium account.

I know how to test if the name is alredy used by a premium, but I dont know how to check if the player connectet with a premium or a cracked account.

Code:

Player-Login
-> Test if the player is premium:
  ->If false: Test if name is already bought by a Premium-Player
    -> If true: Kick the Player "This name is already used by a premium-player"
    -> If false: Nothing ^^

(Ignore the println() - it's just for debuging) ^^

Code:

    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
        String n = p.getName();
        boolean prem;
        try {
        URL url = new URL("https://minecraft.net/haspaid.jsp?user=" + n );
        String isPremium = new BufferedReader(new InputStreamReader(url.openStream())).readLine().toUpperCase();
        prem = Boolean.valueOf(isPremium);
        System.out.println("1");
        System.out.println(n);
        System.out.println(prem);
            if(prem){
            e.setJoinMessage(n + " hat Premium");
            System.out.println("2");
            }
            } catch (Exception e2) {
            p.sendMessage("Invalid player!");
            System.out.println("3");
        }

How it may work:

Code:

1) Client connects with the Server
2) Client wait for the Serverid...
3) Server checks with help of haspaid.jsp, if the player is premium or cracked.
4) If yes, he will give back the true Serverid
5) If no, "-" will send back
 
And the "minecraft.net" check will be removed for the Cracked player

Maybe a useful link:

Code:

http://session.minecraft.net/game/joinserver.jsp?user=<USERNAME>&sessionId=<SESSION ID>&serverId=<SERVER ID>

AFAIK you cant check that but of course a Player with a premium account cant have the Name of another Player with a premium account so you dont Need to check that

 

DoppelRR I am 99% sure that it's possible. As far as I know there is a Server with a plugin like the Plugin I want

And I dont want a cracked player joining with a premium name... That is all ^^

 

Blender4Me I feel like this in some way would violate EULA, gotta remember Mojang owns Bukkit, so I would tread lightly.

 

@ferrango And where is the problem? There are so many cracked Servers and I dont know how this would violate EULA :/

So can somebody help me or not :C
Posting that cracked is not good is not helping me

 

Offline mode is not supported.

 

Maybe its not supported, but it works... But it seems like nobody wants to help me :/

 

Blender4Me You won't get help here as it isn't supported here.

 

You're surprised?

 

Blender4Me
When ist not supportet by bukkit you Need to go into NMS

Blender4Me
and of course just go on the Server youve seen it and ask there

Ok... Its solved :3
Solution: Nobody knows how it works ^^

 

The best way you can get people from playing as different players, is getting a password plugin.

 

Locked. We do not support offline mode.
