RE: Java to RPG question -- JAVA400-L

If you want to send multiple data items (a structure) in a single parameter
you have a couple ways to go using Toolbox objects.  First, you can use the
Toolbox converters to convert the items one at a time, sticking them into
the same byte array.  Your code would is responsible for making sure the
byte array is correctly formed.  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
http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzahh/javadoc/DQProducerExample.html.

 A third choice is PCML.  This is an XML language for calling programs.  In
XML you describe the format of the parameter, then PCML does the work of
calling the program.  See the PCML section of the Toolbox pub
(http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzahh/pcml.htm)

for more information.

Dave, Thanks for your reply. I think, I have to further describe my
question. I've been able to send a few parameters to the RPG and get them
back. What I'm trying to do is to send data structure of fields with
different attributes, maybe even externally described DS(is that possible
at all?).

Thanks again, Oleg.

I can help a little.  Conversion classes in the IBM Toolbox for Java can
help convert between Java and iSeries formats.  For example, you use the
AS400PackedDecimal class to convert between a Java double and an iSeries
packed decimal number.  The following converts a Java double number into
iSeries packed decimal format and stuff them into a byte array.  It then
reverses the process.  It grabs the numbers out of the bytes byte array and
converts them back into Java numbers.
