Solved Events and Listeners

hello,
i am making a plugin with multiple events and classes
i register the events in the Main class
But i get an error in the console when i use:
getServer().dispatchCommand(getServer().getConsoleSender(), "pex user " + player.getName() + " group set member");
in any others class as Main.

Whats wrong?
- Sheep (sorry for bad English)

Main Class:

package me.theholysheepnl.TheSheepGames;

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

public class Main extends JavaPlugin implements Listener {

@Override
public void onEnable() {
Bukkit.getServer().getPluginManager().registerEvents(new BlockListener(),this);
Bukkit.getServer().getPluginManager().registerEvents(new JoinListener(),this);
Bukkit.getServer().getPluginManager().registerEvents(new NobreakNoob(),this);
Bukkit.getServer().getPluginManager().registerEvents(new SafeNoob(),this);
Bukkit.getServer().getPluginManager().registerEvents(new SpongeProtect(),this);
Bukkit.getServer().getPluginManager().registerEvents(new SignEvent(),this);
Bukkit.getServer().getPluginManager().registerEvents(new NoobMember(),this);
Bukkit.getServer().getPluginManager().registerEvents(this,this);
}
}

NoobMember Class:

package me.theholysheepnl.TheSheepGames;

import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class NoobMember extends JavaPlugin implements Listener {

@EventHandler(priority = EventPriority.NORMAL)
public void onClick(PlayerInteractEvent event){
Player player = event.getPlayer();
if(event.getAction() == Action.RIGHT_CLICK_BLOCK || event.getAction() == Action.LEFT_CLICK_BLOCK){
if(event.getClickedBlock().getType() == Material.NOTE_BLOCK)
if(player.getItemInHand().getType() == Material.NAME_TAG){
getServer().dispatchCommand(getServer().getConsoleSender(), "pex user " + player.getName() + " group set member");
player.sendMessage(ChatColor.GREEN + "Congratulations you are now a Member!");



}
}

}
}
