Serialisation problem: invalid stream header

[Jared Cope]

Hi,

I have a wierd error at the moment and not sure how to deal with it. I have some code that writes 3 objects to a file on the local file system and then some code to read back the first 2 of those objects later on.

This works perfectly fine for myself and many other people in my London office, but fails for one person in an Oslo office.

Serialisation code is:

  
FileOutputStream fos = new FileOutputStream(storeDirectory
+ File.separator + filename);
ObjectOutputStream oo = new ObjectOutputStream(fos);
oo.writeObject(afx.getHeadline());
oo.writeObject(new Date());
oo.writeObject(afx);
oo.flush();
fos.close();
oo.close();

De-serialisation code is (where storyDetails is an Object array):

  
FileInputStream fis = new FileInputStream(storeDirectory
      + File.separator + fileName);
ObjectInputStream oi = new ObjectInputStream(fis);
storyDetails[0] = (String) oi.readObject();
storyDetails[1] = oi.readObject(); //date
fis.close();

I get an java.io.StreamCorruptedException: invalid stream header error in the de-serialisation code. I am at a bit of a loss at how to proceed because this works for most other people.

Has anyone had a similar problem before?
Could it possibly have something to do with different JRE's or O/S's?

Any help would be appreciated.

Cheers, Jared.
