RE: Java to RPG question

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
