Hallo,
Ich habe heute mal wieder ein kleines Problem die Methode getWorldguard() stößt eine NullPointerException aus.
Hier einmal der Server log:
Hier einmal den WorldguardHandler:
ReturnClass, welche die Location aus der Datenbank holt.
Vielen Dank für Hilfe im Voraus !

}ReturnClass, welche die Location aus der Datenbank holt.
Code:

public String url = "jdbc:mysql://localhost:3306/Datenbank";
public Location getVectorLeft(String pn, World w) throws SQLException {
Location loc = null;
Statement stmt = null;
ResultSet rs = null;
Connection con = DriverManager.getConnection(url, user, pass);
stmt = con.createStatement();
rs = stmt.executeQuery("SELECT x, y, z FROM users WHERE name='"+pn+"';");
while(rs.next()) {
double x = rs.getDouble(1) + 222;
double y = rs.getDouble(2);
double z = rs.getDouble(3) + 222;
loc = new Location(w,x,y,z);
}
return loc;
}
