First you'll need to declare your packets+size inside WPD:
 

    private final static int ITEM_ON_FLOOR_EXAMINE = 102;

Then add this under processPackets method:

        } else if (packetId == ITEM_ON_FLOOR_EXAMINE) {
            int y = stream.readUnsignedShort(); //CLIENT SENDS THEM BACKWARDS ON PURPOSE
            int x = stream.readUnsignedShortLE();
            int id = stream.readUnsignedShort();
            boolean forceRun = stream.readUnsigned128Byte() == 1;
            player.getPackets().sendItemMessage(0, 15263739, id, x, y, ItemExamines.getExamine(new Item(id))); // ChatboxMessage

Inside WPE:

	public void sendItemMessage(int border, int colour, int id, int x, int y, String message) {
        sendGameMessage(message);
        sendGlobalString(306, message);
        sendGlobalConfig(1699, colour); //"color" - Default; 1 - Black
        sendGlobalConfig(1700, border); //"border" - Default; 0 - White; 1 - Red; 2 - No Border
        sendGlobalConfig(1695, 1);
        sendItemInterface(new Item(id), new WorldTile(x, y, player.getPlane()), true, 746, 0, 1177);
    }
	    public void sendItemInterface(Item item, WorldTile tile, boolean noclipped, int windowId, int windowComponentId, int interfaceId) {
        int[] xteas = new int[4];
        OutputStream stream = new OutputStream(30);
        stream.writePacket(player, 36);
        stream.writeByte128(noclipped ? 1 : 0);
        stream.writeIntV2(xteas[0]);
        stream.writeIntLE((windowId << 16) | windowComponentId);
        stream.writeIntV1(xteas[1]);
        stream.writeShort(item.getId());
        stream.writeIntV1(xteas[2]);
        stream.writeInt(xteas[3]);
        stream.writeShortLE(interfaceId);
        stream.writeInt((tile.getPlane() << 28) | (tile.getX() << 14) | tile.getY());
        session.write(stream);
    }

Actually needed this, thanks man.

i don't have this yet, thanks a lot!
