Re: problems with ProgramCall

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,
