    OK, so I've been making a plugin for a private server, and I had all the code squeezed into one class, and it gave an error when you did the commands, but other than that it worked. But I took the tab completer and added that and the command to other classes. I have it set in the onEnable(), but now it just won't work, and it gives a big long error and I obviously don't know what to do.
    Main:
    Code:
    package me.ldsessions;

import java.util.List;

import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin {
    public static int TimpCity;
    public static int ldsessions;
    public static int Spiesmonkey;
    public static int PokemonHero;
    public static int Broville;
    public static int Eaglehead;
    public static int blackhead;
    public static int whoville;
    public static List<String> hasVoted;

    @SuppressWarnings("deprecation")
    public void onEnable() {
        saveDefaultConfig();
        getConfig().options().copyDefaults(true);
        saveConfig();
        getCommand("vote").setExecutor(new Vote());
        getCommand("vote").setTabCompleter(new TabContrustor());
        TimpCity = 0;
        ldsessions = 0;
        Spiesmonkey = 0;
        PokemonHero = 0;
        Broville = 0;
        Eaglehead = 0;
        blackhead = 0;
        whoville = 0;
        if (this.getConfig().getBoolean("refresh") == true) {
            Bukkit.getScheduler().scheduleAsyncRepeatingTask(this,
                    new Runnable() {
                        public void run() {
                            TimpCity = 0;

    Why do you have 2 classes that extend javaplugin ?

    Oh, @CrystallFTW , it's so I can access the config file, because I'm a n00b and don't know how to access it without extending it.

    @Leviticalpixel10 only your main class should extend JavaPlugin. Also to acces your main class just add a new line before onEnable()
    Code:
    static JavaPlugin instance;
    and in your onEnable() add
    Code:
    this = instance;
    and in your other classes use
    Main.instance.whatever
    for example
    Code:
    Main.instance.getConfig().getString(someString);
    I know this isn't the best way to do that but, it works.
    And remove the "extends JavaPlugin" from all the classes besides your main class.

    Code:
    if (args[0].equalsIgnoreCase("Whoville")) {
                int votecount;
                votecount = 1;
                Main.whoville = Main.whoville + votecount;
                player.sendMessage(plugin.getConfig().getString("votemessage"));
            }
    this is where the problem is, it's a nullPointerExeption, but I don't see whats wrong. It's not specific to just this argument though. and BTW it's the line that has votecount = 1 @CrystallFTW @teej107

    @Leviticalpixel10 You can replace
    Code:
    int votecount;
votecount = 1;
    with
    Code:
    int votecount = 1;
    And
    Code:
    Main.whoville = Main.whoville + votecount;
    with
    Code:
    Main.whoville += votecount;
    But I don't think that's your problem, could we see the stack trace?
    It might not be that line/file.

    I can tell you already that is not the line where the exception is thrown. Primitives can never be null.

    @Leviticalpixel10 I guess you initialized your Main, so did you create a config.yml?

    @Leviticalpixel10
    Code:
    if (args.length == 0) {
    player.sendMessage("Usage: /Vote <City>");
}
    Add "return false;" after the sendMessage to prevent your command from executing the rest (and possibly causing errors).

    Also, use "else if" rather than plenty of "if" statements, you'll get slightly better performances.

    PS: You can use the edit button not to double-post.
