Re: Writing to an AS/400 physical file with fileOutputStream

Hi Patrick,

tried using java.io.RandomAccessFile...
but got the orginal undesired results.

Hmm, I'm surprised. Something resembling:

import java.io.*;

public class TestWriteAS400File
{
 public static void main(String[] args) throws Exception
 {
   RandomAccessFile raf =
     new RandomAccessFile("myFileName", "rw");

   raf.seek( 0 );
   raf.writeChars( "I want this to be record 1" );
   raf.seek( 132 );
   raf.writeChars( "I want this to be record 2" );
   raf.seek( 264 );
   raf.writeChars( "I want this to be record 3" );

   raf.close();
 }  // end main

} // end


should work. Worst case, I would think, writing 132 byte arrays again.

   Sorry, can't test until tomorrow, if then.  Got to head out to a local
JUG meeting.

Joe Sam,

You are correct on all points.


I changed the class so that it space-padded the data to 132 and it wrote

three records like I wanted.

I changed the class again and tried using java.io.RandomAccessFile and
even did java.io.RandomAccessFile.setLength(132) on the file but got the
orginal undesired results.

Thanx for the suggestions, PLA
