Try this,

UseItem.java

import net.sf.l2j.Config;
+import net.sf.l2j.gameserver.Olympiad;
import net.sf.l2j.gameserver.handler.IItemHandler;

L2ItemInstance item = activeChar.getInventory().getItemByObjectId(_objectId);

		if (item == null)
                               return;

+                      int lolz0r = item.getItem().getCrystalType();
+                      if (activeChar.isInOlympiadMode() || Olympiad.getInstance().isRegisteredInComp(activeChar) || +activeChar.getOlympiadGameId() > 0)
+                      {
+                            if (lolz0r == L2Item.CRYSTAL_S || lolz0r == L2Item.CRYSTAL_S80 || lolz0r == L2Item.CRYSTAL_S84)
+                            {
+        	                  activeChar.sendMessage("You may only use items up to Grade A in the Grand Olympiad Games.");
+                                  return;
+                            }
+                      }

Olympiad.java

public class Olympiad
{
/**
 *
 * @author  ascharot

 */
+      private int _objectId;
private class OlympiadGameTask implements Runnable
{
	public L2OlympiadGame _game = null;

if (!_inCompPeriod)
       {
           sm = new SystemMessage(SystemMessageId.THE_OLYMPIAD_GAME_IS_NOT_CURRENTLY_IN_PROGRESS);
           noble.sendPacket(sm);
           return false;
       }

+      L2ItemInstance item = noble.getInventory().getItemByObjectId(_objectId);
+      int lolz0r = item.getItem().getCrystalType();
+      if (lolz0r == L2Item.CRYSTAL_S || lolz0r == L2Item.CRYSTAL_S80 || lolz0r == L2Item.CRYSTAL_S84)
+      {
+          noble.sendMessage("You cannot use S grade equipment at the Grand Olympiad games.");
+          return false;
+      }

 

in useitem.java --->where i must add the import?? (my useitem.java)-->http://pastebin.com/5WY4ZVKs

and in olympiad.java i cant find where i must add this code

+      private int _objectId;

my olympiad.java-->http://pastebin.com/2GsdGYFR

 

and

+      L2ItemInstance item = noble.getInventory().getItemByObjectId(_objectId);

+      int lolz0r = item.getItem().getCrystalType();

Not sure about epilogue,try this:

 

import com.l2jserver.Config;

import com.l2jserver.gameserver.GameTimeController;

+import com.l2jserver.gameserver.model.olympiad.Olympiad;

has problem :S

Private int _object...you can add it here:

 

public class Olympiad
{
        private int _objectId;
protected static final Logger _log = Logger.getLogger(Olympiad.class.getName());
protected static final Logger _logResults = Logger.getLogger("olympiad");

Has problem?what do you mean?

[manos2864]

L2ItemInstance item = noble.getInventory().getItemByObjectId(_objectId);

int lolz0r = item.getItem().getCrystalType();

if (lolz0r == L2Item.CRYSTAL_S || lolz0r == L2Item.CRYSTAL_S80 || lolz0r == L2Item.CRYSTAL_S84)

{

 

It say

L2iteminstance cannot be resolve to a type

and

multiple markers at this line: l2item cannot be resolve

[DnR]

Add the import for l2iteminstance in Olympiad.java.

Multiple markerS? Oo?It works normally for me...

Add the import i told you,and check it again.

Instead of this:if (lolz0r == L2Item.CRYSTAL_S || lolz0r == L2Item.CRYSTAL_S80 || lolz0r == L2Item.CRYSTAL_S84)

try this:if (lolz0r == L2Item.CRYSTAL_S)

 

Compile,login to check if it works and i ll modify it for s80 and s84.

I put this if (lolz0r == L2Item.CRYSTAL_S) but again say L2item cannot be  resolve

lol,import for l2item doesnt exist either.import com.l2jserver.gameserver.templates.item.L2Item;

Revert my previous post and add the import.

In Olympiad.java,change the code to be like this:

      L2ItemInstance item = noble.getInventory().getItemByObjectId(_objectId);
      int lolz0r = item.getItem().getCrystalType();
      if (item != null)
      {
          if (lolz0r == L2Item.CRYSTAL_S || lolz0r == L2Item.CRYSTAL_S80 || lolz0r == L2Item.CRYSTAL_S84)
          {
              noble.sendMessage("You cannot use S grade equipment at the Grand Olympiad games.");
              return false;
          }
      }

             return false;
         }
     }

this will fix my error?

EDIT

 

     L2ItemInstance item = noble.getInventory().getItemByObjectId(_objectId);
     int lolz0r = item.getItem().getCrystalType();
     if (item != null)
     {
         if (lolz0r == L2Item.CRYSTAL_S || lolz0r == L2Item.CRYSTAL_S80 || lolz0r == L2Item.CRYSTAL_S84)
         {
             noble.sendMessage("You cannot use S grade equipment at the Grand Olympiad games.");
             return false;
         }
     }

when i put in the end the }then in if (item != null) say redudant null check:the variable item cannot be null at this location but if i delete } then everything its ok
