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

Hi Patrick,

You didn't say, but I assume that you got one record containing

"I want this to be record 1I want this to be record 2I want this to be
record 3"

   Stream files just see and read one byte after another ( more or less -
chars for Reader/Writers ).  I haven't had a need to write directly to a
physical file this way, but I would expect that the only way your code could
work would be to ensure that you write 132 bytes ( the record length ) each
time.  And that may not work with straight stream files.  In general, Java
uses java.io.RandomAccessFile to work with fixed-length records.

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

Hello

Does anyone know how I could force a new record to be written to an
AS/400 physical file in the test code below (without using any toolbox
classes)?

I used the following command to create the physical file on the AS/400:

crtpf trash/test rcdlen(132)

I end up with one record instead of 3.

Here is the Java test code:



import java.io.FileOutputStream;

public class TestWriteAS400File {

public static void main(String[] args) throws Exception {

   FileOutputStream fileOutputStream =
     new FileOutputStream("/qsys.lib/trash.lib/test.file/test.mbr");

fileOutputStream.write("I want this to be record

1".getBytes("Cp037"));

fileOutputStream.write("I want this to be record

2".getBytes("Cp037"));

fileOutputStream.write("I want this to be record

3".getBytes("Cp037"));

fileOutputStream.close();

}

}


Thanx, PLA
