If you are using a numeric field from RPG most likely it is AS400ZonedDecimal or AS400PackedDecimal. From your description of the characters, I'd bank on packed. Probably 3/0 (three positions, zero decimal positions). Something like this
BigDecimal result = (BigDecimal)new AS400PackedDecimal(3,0).toObject(parmList[0].getOutputData());
I'm working from memory here, but I believe the java object returned by the toObject of AS400PackedDecimal is BigDecimal.

Subject: Retrieving integer parameter after JT400 ProgramCall?
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: "└?" "
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( txt5.toBytes(VanguardLocation),5);
parmList[1] = new ProgramParameter( txt4.toBytes(Integer.toString(NextSequence)),4);
// Set up program call and run.
ProgramCall pgm = new ProgramCall(sys, "/QSYS.LIB/LG.LIB/INCGLJSEQ.PGM", parmList);
if (pgm.run() != 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() ) );
sys.disconnectService(AS400.COMMAND);
}
The output:
Output Data 0: WV
Output Data 1: └?
I am expecting a number around 25658 (that would be the next sequence number 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!
Thanks,
Loyd
