Set coordinates?

Hey guys, my plugin DisconnectReset is about to update and one of the new features is that you can set reset position through a command, but, i get an error.

I have no idea what i should do.

New command code:

Code:

public boolean onCommand(CommandSender sender, Command command,
            String label, String[] args) {
        if(label.equalsIgnoreCase("dr")){
            if(args[0].equalsIgnoreCase("setspawn")){
                Player p = (Player) sender;
                if(p.hasPermission("dr.setspawn")){
            Location l = p.getLocation();
            double x = l.getX();
            double y = l.getY();
            double z = l.getZ();
            World w = l.getWorld();
            String ws = w.toString();
            String wse = ws.replace("CraftWorld{name=", "");
            String wst = wse.replace("}", "");
            this.getConfig().set(path + ".x", x);
             this.getConfig().set(path + ".y", y);
             this.getConfig().set(path + ".z", z);
             this.getConfig().set("Spawn world", ws);
             this.saveConfig();

                p.sendMessage(ChatColor.GREEN + "New spawn set.");

                }else{
                    p.sendMessage(ChatColor.RED + "Sorry, you ain't got permissions to do that.");
                  
                }
              
            }else{
              
              
            }
          
          
        }

      
      
      
        return false;
    }

The code that reads the config:

Code:

      @EventHandler
        public void onPlayerDisconnect(PlayerQuitEvent event) {
          Player p = event.getPlayer();
        if(!p.hasPermission("dr.bypass")) {
          PlayerInventory pi = p.getInventory();
          int x = this.getConfig().getInt(path + ".x");
          int y = this.getConfig().getInt(path + ".y");
          int z = this.getConfig().getInt(path + ".z");
          World w = Bukkit.getWorld(this.getConfig().getString("Spawn world"));
          Location loc = new Location(w, x, y, z);
          p.teleport(loc);

          pi.clear();
          pi.setHelmet(new ItemStack(Material.AIR));
          pi.setChestplate(new ItemStack(Material.AIR));
          pi.setLeggings(new ItemStack(Material.AIR));
          pi.setBoots(new ItemStack(Material.AIR));
    
        }

The config:

Code:

Spawn coordinates:
  x: 456
  y: 115
  z: 443
Spawn world: world

The error:

Code:

Please help!
Thank you in advance!

Where is 'path' defined?

 

Path is a string defined in the beginning of the class,

Code:

public class DR extends JavaPlugin implements Listener{
    String path = "Spawn coordinates";

@Fillefixsweden
Doubt anyone would go through your code to see what wrong but l can try to give it a go
Have to tried to find the source of the problem - like disabling certain parts of the plugin till you get what the problem is?

 

@Ruptur

Yes, i have tried debugging it but i could'nt get it working, that's why i posted it here.

I think it's something about the world, it saves as CraftWorld etc. and then can't read it because of that. That's why i have tried to replace the surrounding with nothing.

 

The use of PlayerJoinEvent

 

@Fillefixsweden Not a whole lot of people actually use the error to its fullest extent:

Go find line 91 in your DR class. That is what is causing the error.

 

@Dudemister1999 Yes i'm fully aware of that, the problem is what in that line is causing the error.
