Java 3d object serialization problem

Hi friends....

Try to writing a program which create binary file of java 3d objects(such as sphere, colorcube...) for later use. But before doing this I have to serialize the objects, but I can't do it, error occurred.

lets see the program ----

The following class is the main class which create a ColorCube object and write to binary file

Code:

---

import com.sun.j3d.utils.geometry.ColorCube;
import java.io.*;

public class SerializeDemo
{
  public static void main(String [] args)
  {
      DoSerialize e = new DoSerialize();
      e.cc = new ColorCube(1.4);
      try
      {
        FileOutputStream fileOut = new FileOutputStream("e://employee.txt");
        ObjectOutputStream out = new ObjectOutputStream(fileOut);
        try
        {
        out.writeObject(e);
        }catch(NotSerializableException i){i.printStackTrace();}
        out.close();
          fileOut.close();
      }catch(IOException i)
      {
          i.printStackTrace();
      }
  }
}

---

This is the serializable class ---

Code:

---

import com.sun.j3d.utils.geometry.ColorCube;


public class DoSerialize implements java.io.Serializable
{
  public ColorCube cc;
}

---

And the errors are ----

Code:

---

java.io.NotSerializableException: com.sun.j3d.utils.geometry.ColorCube
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1180)
        at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1528)
        at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1493)
        at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1416)
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1174)
        at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:346)
        at SerializeDemo.main(SerializeDemo.java:25)
BUILD SUCCESSFUL (total time: 2 seconds)

So how to overcome this problem?
Please help.
Thanks......

Did you read the API doc for the error? The exception is a class that is defined in the API doc:
Java Platform SE 7

Thanks for your reply.
Yes I read the API doc, but can't understand exactly what to do? By dafult ColorCube object of java 3d is already implemented serializable interface, so do I need to serialize it again?

Yes, I did and I was wrong. So I need to implement serializable interface to the ColorCube class
