You might want to take a look at PCML and using the It's MUCH better to deal with.

It's been a while, but I'm pretty sure you can't use AS400Text for an
integer parameter. You have to use AS400Bin4.

AS400Bin4 bin4 = new AS400Bin4();
byte[] b = bin4.toBytes(nextSequence);
parmList[1] = new ProgramParameter(b);

On a side note, in Java variables should always begin with a lowercase

String vanguardLocation = "WV";
Integer nextSequence = new Integer(0);

I am not a Java programmer so please be kind. :)

I have a simple Java program which calls a RPGLE program using ProgramCall
in JT400.jar. The call works (it increments a sequence number in a file),
but I am unsure how to retrieve the integer parameter after the call. The
program returns two DOS looking characters like a box corner and a diamond
or question mark. Using parseInt does not work, with error
"java.lang.NumberFormatException: For input String: "â?" "

Is this an EBCDIC ASCII translation issue? The character parameter shows
correctly in both the RPG and Java (testing in Windows). Am I even passing
(and receiving) the integer correctly? The called RPG program does run
because I see the sequence number increasing.

Java snippet:

String VanguardLocation;
Integer NextSequence;
VanguardLocation = "WV ";
NextSequence = 0;

// Create field types for parameters.
AS400Text txt5 = new AS400Text(5);
AS400Text txt4 = new AS400Text(4);

// Create parameter array and populate.
ProgramParameter[] parmList = new ProgramParameter[2];
parmList[0] = new ProgramParameter(
parmList[1] = new ProgramParameter(

// Set up program call and run.
ProgramCall pgm = new ProgramCall(sys,
if ( != true) {
AS400Message[] messageList = pgm.getMessageList();
} else {
System.out.println("Output Data 0: " +
(String)txt5.toObject( parmList[0].getOutputData() ) );
System.out.println("Output Data 1: " +
(String)txt4.toObject( parmList[1].getOutputData() ) );

The output:

Output Data 0: WV
Output Data 1: â?

I am expecting a number around 25658 (that would be the next sequence
from the file).

The RPG prototype:

d incgljseq pr extpgm('INCGLJSEQ')
d inlocation 5a const
d outuseseq 10i 0

Any info to help this Java newbie out is appreciated!
