Solved onPlayerJoin Problem

i know it,im again here :-(
it might be not the biggest problem but its weird that its not running and also does not give any errors this is what i got :

Code:

package me.peterxonwiixx.nightvision;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class OnJoin extends JavaPlugin implements Listener {

    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event) {
        Player p = event.getPlayer();
        p.sendMessage(ChatColor.AQUA + "this" + ChatColor.BLACK + "server" + ChatColor.BLUE + "use" + ChatColor.BOLD
                + "your" + ChatColor.DARK_AQUA + "plugin" + ChatColor.DARK_BLUE + "NightVision");

    }
}

 

@timtower shame on me,thanks anyway.i just didnt think about that but it now works tho <3
