[jdom-interest] XMLOutputter clipping text ... a bug?

[William Krick]

I modified my sample code to fill a buffer directly from the FileInputStream
and then write it directly to the FileOutputStream, eliminating the
XMLOutputter from the equasion.  It works correctly.  So the problem has
something to do with the way XMLOutputter talks to FileOutputStream...


    String fileName = "test.xml";
    File f = null;
    int c;
    int[] buffer = new int[4096];
    int size = 0;

    //load the data from the xml file
    FileInputStream fis = null;
    try {
      f = new File(fileName);
      fis = new FileInputStream(f);

      int i=0;
      while ((c = fis.read()) != -1) {
        buffer[i] = c;
        i++;
      }
      size = i;
    }
    catch (Exception ex) {
    }
    finally {
      try { fis.close(); } catch (Exception ex) {}
    }

    // write the data back out to the file
    FileOutputStream fos = null;
    try {
      f = new File(fileName);
      fos = new FileOutputStream(f);

      int i=0;
      while (size-i > 0) {
        fos.write(buffer[i]);
        i++;
      }
    }
    catch (Exception ex) {
    }
    finally {
      try { fos.close(); } catch (Exception ex) {}
    }

It comes out fine in system out but not in the file.

If I send the output to a different file instead of the same file, it works
correctly.

I would think that as long as I close the FileInputStream before I open the
FileOutputStream, it should be okay using the same file.

I'm at a loss as to what the heck is happening here.

I've never heard of this before.  I'm going to guess it has to do with
your stream.  Dump it to System.out for another view.
