NotSerializable Exception

Edit: I changed HomeLocation to implement Serializable but the problem still occurs, it looks like it is coming from the bukkit vectors? Here is my exact error log:

I'm having a problem when I try and save my datatype to a file when the server closes.

My datatype is a hashmap of Strings and a double array, a vector, another double array, and another vector.

The code is as below. I use the SLAPI that it has on the plugin tutorial page, I'm not really sure how to change it so they are serializable or getting rid of that statement.

The code for my object is:

Code:java

package com.gmail.betorages.homecommand;
 
import org.bukkit.util.Vector;
 
 
public class HomeLocation{
 
private double[] position;
private Vector direction;
private double[] lastPosition;
private Vector lastDirection;
 
public HomeLocation(double[] position, Vector direction, double[] lastPosition, Vector lastDirection){
this.direction = direction;
this.position = position;
}
 
public double[] getPosition(){
return this.position;
}
 
public Vector getDirection(){
return this.direction;
}
 
public double[] getLastPosition(){
return this.lastPosition;
}
 
public Vector getLastDirection(){
return this.lastDirection;
}
 
public void setLastDirection(Vector direction){
this.lastDirection = direction;
}
 
public void setLastPosition(double[] position){
this.lastPosition = position;
}
}

And where it saves the file:

Code:java

@Override
public void onDisable() {
getLogger().info("Just Kidding! Had ya goin though right?");
try{
SLAPI.save(playerHomes,"plugins\\HomeCommand\\playerHomes.bin");
}catch(Exception e){
e.printStackTrace();
}
}

 

For SLAPI to be able to save a class (including a collection/hashmap of it), it needs to implement Serializable:

Code:

public class HomeLocation implements Serializable {

And when you get a warning asking if you want to add a variable called serialVersionUID, click yes.

 

I added what you said and I'm still getting the error, here is the new code:

Code:java

package com.gmail.betorages.homecommand;
 
import java.io.Serializable;
 
import org.bukkit.util.Vector;
 
 
public class HomeLocation implements Serializable{
 
    /**
    *
    */
    private static final long serialVersionUID = 1L;
    private double[] position;
    private Vector direction;
    private double[] lastPosition;
    private Vector lastDirection;
 
    public HomeLocation(double[] position, Vector direction, double[] lastPosition, Vector lastDirection){
        this.direction = direction;
        this.position = position;
    }
 
    public double[] getPosition(){
        return this.position;
    }
 
    public Vector getDirection(){
        return this.direction;
    }
 
    public double[] getLastPosition(){
        return this.lastPosition;
    }
 
    public Vector getLastDirection(){
        return this.lastDirection;
    }
 
    public void setLastDirection(Vector direction){
        this.lastDirection = direction;
    }
 
    public void setLastPosition(double[] position){
        this.lastPosition = position;
    }
}
 

Code:java

package com.gmail.betorages.homecommand;
 
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
 
/** SLAPI = Saving/Loading API

*/
public class SLAPI implements Serializable
{
    /**
    *
    */
    private static final long serialVersionUID = 1L;
    public static <T extends Object> void save(T obj,String path) throws Exception
    {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(path));
        oos.writeObject(obj);
        oos.flush();
        oos.close();
    }
    public static <T extends Object> T load(String path) throws Exception
    {
        ObjectInputStream ois = new ObjectInputStream(new FileInputStream(path));
        T result = (T)ois.readObject(); //This is where the warning is
        ois.close();
        return result;
    }
}
 
 

Not sure if this is causing anything but for the SLAPI I'm getting a warning:

Type safety: Unchecked cast from Object to T SLAPI.java /HomeCommand/src/com/gmail/betorages/homecommand line 30 Java Problem
