    Hello, (sorry for bad english) I have a problem with loading inventories from the config file. I have already seen several forum posts with the similar problem, but did not help ...

    Code:
    public static void getInventory(Player player, WorldGroup worldGroup) {
        String configarmor = "WorldGroups." + worldGroup.getName() + "." + player.getUniqueId() + ".Inventory.Armor";
        String configcontent = "WorldGroups." + worldGroup.getName() + "." + player.getUniqueId() + ".Inventory.Armor";
        try {
            player.getInventory().clear();
            ItemStack[] armorcontent = (ItemStack[]) config.get(configarmor);
            player.getInventory().setArmorContents(armorcontent);
            ItemStack[] content = (ItemStack[]) config.get(configcontent);
            player.getInventory().setContents(content);
        } catch (NullPointerException e) {
            saveInventory(player, worldGroup);
        }
    }
    (The path is definitely correct ) When I reload the server, I get a ClassCastException on the first execution in the line where the variable "configarmor" is declared (Line41) ...

    Code:
    org.bukkit.command.CommandException: Unhandled exception executing command 'world' in plugin ServerSystem v1.1

    @Der_Zauberer You can do getItemStack()
    And I am assuming that you have a list of ItemStacks, not a single one. Think that that is the issue.

    @timtower Ok, but how can I get the ItemStack from a list?

    This is my config, with the saved inventories:

    @Der_Zauberer What I do in situations like this is storing the index as well. Then you can call getItemStack.

    It works! Thank you very much ;-)

    Code:
    public static void saveInventory(Player player, WorldGroup worldGroup) {
        String configarmor = "WorldGroups." + worldGroup.getName() + "." + player.getUniqueId() + ".Inventory.Armor";
        String configcontent = "WorldGroups." + worldGroup.getName() + "." + player.getUniqueId() + ".Inventory.Content";
        for (int i = 0; i < player.getInventory().getArmorContents().length; i++) {
            config.set(configarmor + "." + i, player.getInventory().getArmorContents()[i]);
        }
        for (int i = 0; i < player.getInventory().getContents().length; i++) {
            config.set(configcontent + "." + i, player.getInventory().getContents()[i]);
        }
        player.getInventory().clear();
        saveConfig();
    }
   
    public static void getInventory(Player player, WorldGroup worldGroup) {
        String configarmor = "WorldGroups." + worldGroup.getName() + "." + player.getUniqueId() + ".Inventory.Armor";
        String configcontent = "WorldGroups." + worldGroup.getName() + "." + player.getUniqueId() + ".Inventory.Content";
        player.getInventory().clear();
        ItemStack[] content = new ItemStack[4];
        for (int i = 0; i < 4; i++) {
            if(config.getItemStack(configarmor + "." + i) != null) {
                content[i] = config.getItemStack(configarmor + "." + i);
            }
        }
        player.getInventory().setArmorContents(content);
        content = new ItemStack[41];
        for (int i = 0; i < 41; i++) {
            content[i] = config.getItemStack(configcontent + "." + i);
        }
        player.getInventory().setContents(content);   
    }
