Re: Create a member in a given file?

[josulli4@xxxxxxx]

Hiya,
      little confused by your mail, if you already have the member name as
part of the name supplied to the class, then the member either already
exists in the file or should get created when you create the file.

If you are looking to add an extra member to the file, try the addPhyical
FileMember(String name,  String description) method. This can be found in
the documentation for the AS400File Class which is a super class of
SequentialFile.

I need to create a member in a file.

I have the full name of the member file in an IFSFile object (i.e.
/QSYS.LIB/XQ41EXI01.LIB/EDIPOMATCE.FILE/MACT9S0BYG.MBR) and I intend to
open it as a SequentialFile, create a Record per line and put in the
data I need, and write it to the SequentialFile.

Currently my code looks pretty much like:

----
        IFSFile logMember = new IFSFile(system,
logFile.getAbsolutePath() + "/" + member.getName());

        if (logMember.exists()) {
            throw new IllegalStateException("Member already exists in
error file " + logMember);
        }

        SequentialFile sequentialFile =
getSequentialFileWithRecordFormatSet(system, logMember.getAbsolutePath());
        sequentialFile.open();
        sequentialFile.positionCursorAfterLast();

        Record record1 = sequentialFile.getRecordFormat().getNewRecord();
        record1.setField(0, "UNB01PEVRETUR");
        sequentialFile.write(record1);
--.-. where getSequentialFile looks like

    private SequentialFile getSequentialFileWithRecordFormatSet(AS400
system, String absolutePath) throws AS400Exception,
AS400SecurityException, InterruptedException, IOException,
PropertyVetoException {
        AS400FileRecordDescription recordDescription = new
AS400FileRecordDescription( system, absolutePath);

        SequentialFile sequentialFile = new SequentialFile(system,
absolutePath);
        RecordFormat[] retrieveRecordFormat =
recordDescription.retrieveRecordFormat();
        if (retrieveRecordFormat.length != 1) {
            log.warn("file does not have exactly one member: " +
absolutePath);
        }
        RecordFormat recordFormat = retrieveRecordFormat[0];
        sequentialFile.setRecordFormat(recordFormat);
        return sequentialFile;
    }

------

This is very similar to what I do when reading from a member, but the
only create method I can find creates the sequentialFile, not the
member.  Apparently "create member" is not the right term to search for
either in google or the toolbox manual, so I am a bit lost now.  I don't
grok Cobol, so I have no idea what it might be called instead.

I would appreciate a gentle hint in the right direction.

Best regards,
