Writing files to disk.....

Question

Hi, any ideas why this code to read in an array of bytes (a file) from a server and then write the file to a user chosen directory does not work??
Should I be using a fileObject and not just a fileoutputstream?? I am using an example from a book that just reads in the array of bytes, creates a fileoutputstream and uses its write method to save the file....
Any ideas??
Thanks!
byte[] theDocument = (byte[])objectIn.readObject();
if (theDocument.length > 0)
     //Let user choose where to put this file
     JFileChooser fileChooser = new JFileChooser();
     fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
     fileChooser.setApproveButtonText("Save");
     fileChooser.setApproveButtonToolTipText("Click to save the document in this directory");
     selection = fileChooser.showOpenDialog(null);
     if (selection == JFileChooser.APPROVE_OPTION)
           //Get the address to the folder they chose
           String thePath = fileChooser.getSelectedFile().toString();
           thePath = thePath + fileName;     //FILENAME CREATED & INITIALISED ELSEWHERE AND IS ALWAYS SOMETHING LIKE MYFILE.TXT  FILE NAME MAY HAVE SPACES SOMETIMES, PROBLEM???
           //now write the file out to the folder chosen by the user
           try
                      FileOutputStream fileOut = new FileOutputStream(thePath);
      fileOut.write(theDocument);//Write the array of bytes to disk to save the file!               fileOut.close();                                        System.out.println("We saved the file to disk!"); //THIS IS DISPLAYED WHEN CODE IS RUN!!
           catch (FileNotFoundException FNF)
                      clientLogin.showUserMessage("Could not save the document.  Check that you have permission to write to the chosen destination directory.");
else
           clientLogin.showUserMessage("No document was sent back from the server.");
}

Yes, I am using a serialised byte array to send the file accross the network from server to client. It just seemed a neat way to do it.....
All communication between my server and client is done using objectoutput and objetcinputstreams because i had problems using printwriters, buffered readers and objectstreams on the same socket....
my server has to receive, populate and send back custom user objects so it made sense (to me anyway) to send all communication like that.....
Is there a better way?
Thanks for speedy replies.
