Problems with loading my config.yml

I've been having problems with saving/loading a serializable class of mine to the config.yml. Saving to seems to work fine but when I load it, I get an exception when reading - !!com.gmail.craptik.containerclasses.Forge

So here is my class

Code:

package com.gmail.craptik.containerclasses;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.block.Block;
import org.bukkit.configuration.serialization.ConfigurationSerializable;
import org.bukkit.enchantments.Enchantment;

import com.gmail.craptik.Properties;

public class Forge implements ConfigurationSerializable
{
    private int x = 0, y = 0, z = 0;
    private int diamondStrength = 0, goldStrength = 0, ironStrength = 0;
    private String worldName = "UnitializedString";
    private String owner = "UnitializedString";
    private List<String> users = new ArrayList<String>();
    private Map<Enchantment, Integer> itemEnchantment = new HashMap<Enchantment, Integer>();

    public Forge()
    {

    }

    public Forge(Block block)
    {
        x = block.getX();
        y = block.getY();
        z = block.getZ();
        worldName = block.getWorld().getName();
    }

    public Forge(Location location)
    {
        x = location.getBlockX();
        y = location.getBlockY();
        z = location.getBlockZ();
        worldName = location.getWorld().getName();
    }

    @SuppressWarnings("unchecked")
    public Forge(Map <String,Object> map)
    {
        setX((Integer)map.get("x"));
        setY((Integer)map.get("y"));
        setZ((Integer)map.get("z"));

        setDiamondStrength((Integer)map.get("diamondStrength"));
        setGoldStrength((Integer)map.get("goldStrength"));
        setIronStrength((Integer)map.get("ironStrength"));

        setWorldName((String)map.get("world"));

        setOwner((String)map.get("owner"));
        setUsers((List<String>)map.get("users"));

        setItemEnchantment((Map<Enchantment, Integer>)map.get("enchant"));
    }

    public Map<String, Object> serialize()
    {
        Map<String, Object> map = new HashMap<String, Object>();

        map.put("x", getX());
        map.put("y", getY());
        map.put("z", getZ());
        map.put("diamondStrength", getDiamondStrength());
        map.put("goldStrength", getGoldStrength());
        map.put("ironStrength", getIronStrength());
        map.put("world", getWorldName());
        map.put("owner", getOwner());
        map.put("users", getUsers());
        map.put("enchant", getItemEnchantment());

        return map;
    }

    public static Forge deserialize(Map <String,Object> map)
    {
        Forge forge = new Forge(map);
        return forge;
    }
}

here is my config.yml

Code:

AllowJoining: false
Forges:
- !!com.gmail.craptik.containerclasses.Forge #get the error here
  diamondStrength: 0
  goldStrength: 0
  ironStrength: 0
  itemEnchantment: {}
  owner: PeteyPii
  users: []
  worldName: world
  x: 131
  y: 78
  z: 173
- !!com.gmail.craptik.containerclasses.Forge
  diamondStrength: 0
  goldStrength: 0
  ironStrength: 0
  itemEnchantment: {}
  owner: PeteyPii
  users: []
  worldName: world
  x: 131
  y: 78
  z: 168

also, when there is an item enchantment, i get the same type of string starting with !!, so I probably need to fix that as well

 

@Patrick Wrobel
rewrite the constructors for your forge class, to be actual constructors

For instance here is the source code to one of my plugins, http://www.ccs.neu.edu/home/edpoon/SimplyHome/
look under the DelegateLocation class for an example of a configuration serilizable class.

 

ALright, I assume you're talking about my constructors that don't set all of the values. I fixed them, so that they set all the default values, however, it still doesn't work. I'm saving and loading the same way as your plugin, but I'm saving a List<Forge>. Any other ideas?

EDIT: heres the error:

Code:

2011-12-18 19:56:50 [SEVERE] Error occurred while enabling ForgeRepair v0.1 (Is it up to date?): null; could not determine a constructor for the tag tag:yaml.org,2002:com.gmail.craptik.containerclasses.Forge

@Patrick Wrobel
DId you register the class in your main class file?
