RE: Java to RPG question

["Dave Wall" <dawall@xxxxxxxxxx>]

This code comes from the DQ example in the pub but shows what you need to
do.  The interesting stuff is the last three lines.  ProgramProgram returns
you a byte array.  You stuff that byte array into a Record object via the
RecordFormat object.  Then you pull individual data items out of the Record
object.
   BinaryFieldDescription customerNumber =
            new BinaryFieldDescription(new AS400Bin4(), "CUSTOMER_NUMBER");

   BinaryFieldDescription partNumber =
            new BinaryFieldDescription(new AS400Bin4(), "PART_NUMBER");

   CharacterFieldDescription partName =
            new CharacterFieldDescription(new AS400Text(20, as400),
"PART_NAME");
   // etc.

   RecordFormat dataFormat = new RecordFormat();
   dataFormat.addFieldDescription(customerNumber);
   dataFormat.addFieldDescription(partNumber);
   dataFormat.addFieldDescription(partName);
   // etc.

   byte[] returnedData = DataQueueData.getData();
   Record data = dataFormat.getNewRecord(returnedData);
   Integer amountOrdered = (Integer) data.getField("QUANTITY");
   String  partOrdered   = (String)  data.getField("PART_NAME");

Dave, I have only one question left.
I created ProgramParameter with a length of entire DS(Output only).
Call RPG.
Converted parameter to byte array.
Now, how do I convert this array back to the RecordFormat???

Thank's for your help.
Oleg.

  Second, you could use a Toolbox RecordFormat object.  That object is a
collection of converters.  You stick the proper types in the record format,
then tell the object to dump out a byte array that your code sends to the
server.  An example is at
