Ich hoffe ihr könnt mir helfen. Wenn ihr noch mehr Code braucht dann sagt bitte Bescheid. :)

Danke.

I'm StackTrace steht eindeutig, dass die Tabelle, in der deine Nicknames gespeichert sind nicht existiert. (erste Zeile im Stacktrace: "Table... does not exist"
Tabellen kannst du mit dem SQL Statement CREATE TABLE IF NOT EXISTS erstellen. Eine Anleitung dazu gibt es auf google.
Desweiteren empfehle ich dir dringendst, dir noch einmal die Grundlagen der Objektorientierten Programmierung anzueignen. Ich weise da nur auf deine SQL Klasse hin. ^^

Ok. Danke. Werde ich nochmal machen. Hab sowieso noch ein Buch über Java.

Ja, das ist nicht meine Klasse, aber ich hatte halt einen Fehler gemacht....
Und habe das erste mal etwas mit MySQL programmiert und das erste mal ein NickSystem programmiert.

Damit der Spieler sich nicht bewegen kann.
Java: 
player.setWalkSpeed(0); // laufgeschwindigkeit des Spielers wird auf 0 gesetzt
player.setFlySpeed(0);
player.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, Integer.MAX_VALUE, -11)); // Negativer JumpBoost Effekt für kein Springen
players.add(player.getUniqueId());
Damit der Spieler Teleportiert wird:
Java: 
new BukkitRunnable() {
  @Override
    public void run() {
      players.stream().filter(uuid -> Bukkit.getPlayer(uuid) != null).forEach(uuid -> { // Durch eine Liste mit Java 8 Lambda iterieren

Code?

Code: 
[17:11:46 WARN]: Caused by: java.net.UnknownHostException: null: unknown error
Ist die DB IP vlt. null?
 
Wie kann ich es machen das das Plugin z.b.Homes eines Spielers zählt und bei zu vielen eine Fehlermeldung an den Spieler schickt?
 
PHP: 
config.setInt("Homes.Player.Total", int);

Sollte so funktionieren. Habe seit mehr als nem halben Jahr keine config mehr verwendet. Kann evtl. falsch sein (MySQL is 4 the win)

Ich gebe dir eine Lösung, du setzt sie Objektorientiert um ;)

Spieler Objekt -> HashMap<String,HomeObjekt> -> OnCommand -> Home wird in der Config gesaved und zur HashMap mit dem Namen geaddet, wenn map.length < deine maximallänge ist. Beim Joinen lädt er die Homes aus der Config (per ConfigurationSection)
