Hi,

We have been written a small application that saves our data using ObjectOutputStream. We saved our object with writeObject(palet). Palet is an array of data 'Palet[] palet = new Palet[25]'. We seem to beable to save the data but reading it back we get an Exception error.

Our code for reading it back looks like this:


    public void PaletInit() throws IOException, ClassNotFoundException
    {
        boolean blnTemp = true;
        try
        {
            File data = new File("palet.obj");
            ObjectInputStream in = new ObjectInputStream(new FileInputStream(data));

            while(blnTemp == true)
            {
                index = 0;
                palet[index] = (Palet) in.readObject();
            }
            in.close();
        }
        catch (Exception e)
        {
            System.out.println("Error during input");
        }
    }

We currently rewrote our program using binary stream and that works but would like to figure out why we couldn't get the object reading to work.

Read up on serialization.
The class you try to load probably has non-serializable data that isn't properly initialised when loaded.

Took a while but that did it.

Thanks.
