Question

I am saving Data into a .dat file using this Piece of Code:

void saveFile () {

    try {
        FileOutputStream fos = new FileOutputStream ("File.dat", true);
        DataOutputStream dos = new DataOutputStream (fos);
        dos.writeUTF (saves[count][0]);
        dos.writeUTF (saves[count][1]);
        dos.writeUTF (saves[count][2]);
        dos.writeUTF (saves[count][3]);
        dos.writeUTF (saves[count][4]);
        dos.writeUTF (saves[count][5]);
        JOptionPane.showMessageDialog (this, "The Record has been Saved Successfully",
                    "Record Saved", JOptionPane.PLAIN_MESSAGE);
        txtClear ();
        dos.close();
        fos.close();
    }
    catch (IOException ioe) {
        JOptionPane.showMessageDialog (this, "There are Some Problem with File",
                    "Problem", JOptionPane.PLAIN_MESSAGE);
    }

}

I need to have the .dat File Hosted on some Online Domain Say http://Domain.com/File.dat
What would I need to do to the Piece of code In Order to be able to Accomplish the Save?

Answer 1

1- Either the “domain” is managed on the same server, then you just put the file at the correct place (usually under ‘www’ folder, check your web server configuration)

2- It’s another computer, then you’ll have to transfer the file there (FTP? Another Java piece of code using sockets? API given by the host? …)

Unrelated but you should close your Streams in a finally block

xxxxxxxStream s = null;
try {
  s = new xxxxxxxStream();
} catch (WhateverException we) {
  ...
} finally {
  s.close();
}
