RE: problems with ProgramCall -- JAVA400-L

I would suggest that you use PCML, it makes things a lot simpler.

If you are not familiar with PCML you can go to
 http://www-3.ibm.com/services/learning/spotlight/dl/free.html

where there is a free online course titled
IK081 - Using PCML to call AS/400 Programs that covers
PCML. They cover a few samples and explain all the
concepts required to help yourself.

(Also, you can just sit back and listen you do not have to
read every slide).

It could be the way the parameters are declared.  You are defining the
first two parameters as an input/output parameters since you pass in both a
byte array and an int.  The second parameter (the int) is the amount of
output data returned in the parm.  In your case you say 2 bytes are
returned in the first parm and 3 bytes are returned in the second parm.
Try skipping the second parameter and see if that helps.  It would be
        pList[0] = new ProgramParameter(coNo);
        pList[1] = new ProgramParameter(cycleNo);
        pList[2] = new ProgramParameter(7);

Also, ProgramParameter accepts only byte arrays.  If you need to pass a
number to your RPG program use one of the Toolbox converters to convert
your number into a byte array.  Converters are available for most AS/400
numeric types.  For example, if you have a bin 4, use:
          AS400Bin4 bin4 = new AS400Bin4();
          byte AS400Data = bin4.toBytes(myInt);

I'm not sure what I need to so to get this working.  I'm trying to call an
rpg program that takes 3 parms, the first 2 input the 3rd output.  All 3
fields are numeric, the only way I could get it to work without compile
errors was to pass all parms as strings.  I just convert them in the rpg.

When I call the rpg from a green screen passing the same parms it gives the
correct output but when I call from the java app it returns an error code
for the 3rd parm.

I'm guess what I'm looking for would be how to define the java and/or for
the following code?

Here is the java code:
        byte coNo = getKeyCoNo.byteValue();
        byte cycleNo = getKeyCycleNo().byteValue();

        ProgramParameter[] pList = new ProgramParameter[3];
        pList[0] = new ProgramParameter(coNo, 2);
        pList[1] = new ProgramParameter(cycleNo, 3);
        pList[2] = new ProgramParameter(7);

        ProgramCall pgm = new ProgramCall(system,
"/QSYS.LIB/PSSTGUI.LIB/CE1099.PGM", pLis);

.
.
.
            byte[] data = pList[2].getOutputData();
            AS400Text textConverter = new AS400Text(data.length,
getSystem());
            bAcctNo = new BigDecimal((String)
textConverter.toObject(data)).setScale(0);


Here is the RPG:
C           *ENTRY    PLIST
C                     PARM           ECO#    20
C                     PARM           ECYC    30
C                     PARM           EACC    7
C                     MOVE ECO#      CO#
C                     MOVE ECYC      CYCLE#  30


I need some help,
