Serialization Error- EOFException

[Arjun Shastry]

Hi All,
This question might have been asked many times before but was not able to find the solution.!!
On user selection of rows from JTable, I am writing the records to a file using Serialization like this-

try{
        FileOutputStream fos = new FileOutputStream(file,true);
        ObjectOutputStream oos = new ObjectOutputStream(fos);
        for(int k=0;k<messages.length;k++){
        oos.writeObject(messages[k]);
           }
           oos.flush();
        oos.close();
    

Program is able to write the data successfully. While reading the data, when user selects the file,I am trying to deseralize it using follwing code-

 
FileInputStream fis = new FileInputStream("C:\\India\\R22\\User\\e1.dat");
        ObjectInputStream ois = new ObjectInputStream(fis);
        while((message=(AEMessage)ois.readObject())!=null){
          System.out.println(message.getPrefixList());
   

At the end, I am getting EOFException(which from the docuentation is obivious:subclass of IOException).
My question is how to avoid this exception in such cases?Is there any way?
Thanks alot.>

Do it the way most Collection classes do it: write the number of objects first. Then in the reading, you first read back that number, then read exactly that many objects.
