Playerlistener script doesn't work

Hi,

I've made a script a few days ago, I've got some errors out of it but it doesn't work.
I think the script don't start, but bukkit said that the plugin is working.

Could someone help me please?

Scripts:

mcexchange.java

Code:java

package net.mcexchange.auth;
 
 
import org.bukkit.plugin.java.JavaPlugin;
import java.util.logging.Logger;
import org.bukkit.plugin.PluginManager;
import org.bukkit.event.Event;
public class mcexchange extends JavaPlugin
{
   public static final Logger log = Logger.getLogger("Minecraft"); 
   private final mcexchangePlayerListener playerListener = new mcexchangePlayerListener();
 
   public void onEnable() 
   {
       getServer().getPluginManager().registerEvents(playerListener,this); 
   }
 
   public void onDisable() 
   {
 
   }
}
 

mcexchangePlayerListener.java

Code:java

 
 
package net.mcexchange.auth;
 
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerLoginEvent;
import java.net.*;
import java.io.*;
 
 
public class mcexchangePlayerListener implements Listener {
public void onPlayerPreLogin(PlayerLoginEvent event)
{
   String returnvalue = "";
   try
   {
       URLConnection connection = new URL("*cut*").openConnection();
       connection.setDoOutput(true);
       OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
       writer.write(URLEncoder.encode("username","UTF-8")+"="+URLEncoder.encode(event.getPlayer().getName(),"UTF-8"));
       writer.flush();
 
       BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
 
       String line;
       while ((line = reader.readLine()) != null)
       {
           returnvalue = returnvalue+line; 
       }
 
       writer.close();
       reader.close();
   }
   catch (Exception e)
   {
       returnvalue = "Error";
   }
   returnvalue = returnvalue.trim();
if (returnvalue.length() > 0)
{
System.out.println("Kick");
event.disallow (PlayerLoginEvent.Result.KICK_OTHER,returnvalue);
}
}
}
 

 

Add @eventhandler just above public void onPlayerPreLogin(PlayerLoginEvent event)

This article details how to use the new event system.

Thanks, it works
