    you could also just use

    Code:java
    1. Player player = (Player) sender;
    2. sender.sendMessage( //text you want + player.getExp + " " + player.getLevel)

    I'd reccomend making the plugin save the player's XP using a command instead of on join. This method can be called and will store player XP to the config.
    Code:java
    1. public void storeXP(String username)
    2. {
    3.     Player player = Bukkit.getPlayer(username);
    4.     int xp = player.getLevel();
    5.     this.getConfig().set("xp."+username+".lvl");
    6.     player.setLevel(0); // Reset XP after storing
    7. }

    That's what I planned to do, but the problem is, I can't tell players how many xp they have on their bank...

    Well, it's as simple as this;
    Code:java
    1. public int getBankXP(String username)
    2. {
    3. return this.getConfig().getInt("xp."+username+".lvl");
    4. }
    Then somewhere in your onCommand, add this;
    Code:java
    1. sender.sendMessage("Your Bank XP is "+this.getBankXP(sender.getName()));

    How you can't tell? you just use:

    Code:java
    1. sender.sendMessage("You have "+this.getConfig().get("xp."+sender.getName().+".lvl")+" levels!");

    You are using args[0] on line 50, and the args variable is empty, therefore [0] is out of bounds. Just remove the whole if statement that includes args[0].

    Check the length of args with "if args.length == 1" for example, before accessing the index.
    (depending how much arguments you are expecting for a command.)
