Type code out of range, is -84

Posted by Senthoor on December 08, 2001 at 10:30 PM

import java.io.*;

class test implements java.io.Serializable
{
public String x = null;
public int i = 0;

public test(String y, int x)
{
this.x = y;
this.i = x;
}
}

public class FileIO {

public FileIO() {
}
public static void main(String[] args) {

try
{
// writing to the file
FileOutputStream fo = new FileOutputStream("x.dat");
ObjectOutputStream oo = new ObjectOutputStream(fo);

test x = new test("Senthoor",5);
oo.writeObject(x);
oo.flush();
oo.close();
fo.close();

// writing again to the file
fo = new FileOutputStream("x.dat", true);
oo = new ObjectOutputStream(fo);

test y = new test("Luxman",10);
oo.writeObject(y);
oo.flush();
oo.close();
fo.close();

//reading from the file

FileInputStream fi = new FileInputStream("x.dat");
ObjectInputStream oi = new ObjectInputStream(fi);
oi.readObject();
test z = (test)oi.readObject();
System.out.println("String : " + z.x);
System.out.print("int : " + z.i);
fi.close();
}
catch(Exception e)
{
System.out.println("ERROR : " + e.toString());
}
}
}

Whats wrong with this code... I am getting Type code out of range, is -84 when I execute this code. I can write objects for the first time and close the stream and read them back. However when I open the file in append mode and add some more objects and try to read them I am getting Type code out of range, is -84... Please help me...
