maxStack is about how many times you want to share this item!since you put only 1 item (itemId=7569) for share you just need to put how many times you want to share it at maxStack.so delete {1, 1, 1} cuz this is equal for 3 items and add only one value! it would be like private final int[] maxStack = { 9999 } in this way you share your item 9999 times.Try this one and if you have problem message me to give you the whole code...or you can find it at l2j server forum..
