It is up to you to write to and read from a data queue in a consistent format -
it is not structured data.

The calls you are looking for are to QSNDDTAQ and QRCVDTAQ.

Subject:  Data Queues




I have a question about Data Queues.  I have been experimenting with the
Java tool box and have been able to successfully write to and read from the
AS/400 data queue.  I would like to be able to write to the data queue with
a CL program, and then have the Java Client read from it.  Is there a
special format for writing to the data queue that the CL must use in order
for the Client to be able to read it correctly.  I would thing not, but
after looking at the sample code below, which describes the data in the
queue, I began to wonder.

// First create the base data types.
CharacterFieldDescription userId =
   new CharacterFieldDescription(new AS400Text(8),  "USER_ID");
CharacterFieldDescription userName =
   new CharacterFieldDescription(new AS400Text(20), "USER_NAME");

// Build a record format and fill it with the base data types.
RecordFormat dataFormat = new RecordFormat();
dataFormat.addFieldDescription(userId);
dataFormat.addFieldDescription(userName);

Would I just write out 28 bytes with the first 8 bytes being User Id and the
last 20 being User Name.  Or is there some kind of identification that I
have to give to the two fields like I did above in the Java program(USER_ID,
USER_NAME),  Also does anyone know the CL calls to write to/read from the
data queue.
