i have to build an iso 8583 message and for that i used the jpos library which is, according to my researches, the best libray to handle iso 8583 communications. I succeeded to build and send iso 8583 messages with fields in range 0-128 as you can see in this code :
public class SimpleClient {
public ISOMsg sendData() throws ISOException, IOException, org.jpos.iso.ISOException {
ISOPackager packager = new GenericPackager("packager/iso93ascii.xml");
ISOMsg isoMsg = new ISOMsg();
isoMsg.setPackager(packager);
isoMsg.set(new ISOField(0, "1200"));
isoMsg.set(new ISOField(3, "920000"));
isoMsg.set(new ISOField(4, "100000005000"));
isoMsg.set(new ISOField(11, "000001"));
isoMsg.set(new ISOField(12, "144306"));
isoMsg.set(new ISOField(13, "0202"));
isoMsg.set(new ISOField(14, "3012"));
isoMsg.set(new ISOField(15, "1205"));
isoMsg.set(new ISOField(18, "5961"));
isoMsg.set(new ISOField(22, "020"));
isoMsg.set(new ISOField(23, "000"));
isoMsg.set(new ISOField(25, "00"));
isoMsg.set(new ISOField(26, "53"));
// isoMsg.set(new ISOField(28, "000000000"));
isoMsg.set(new ISOField(32, "27610000001"));
isoMsg.set(new ISOField(35, "9876500000306082"));
isoMsg.set(new ISOField(37, "43063829"));
isoMsg.set(new ISOField(41, "20390059"));
isoMsg.set(new ISOField(42, "111120000012"));
isoMsg.set("43", "support@hologram.com");
isoMsg.set("48.1", "12");
ASCIIChannel channel = new ASCIIChannel("127.0.0.1",
5000, packager);
channel.connect();
channel.send(isoMsg);
ISOMsg resIsoMsg = channel.receive();
byte[] msg = resIsoMsg.pack();
// channel.send(msg);
System.out.println("========================================================================================");
String res = ISOUtil.byte2hex(msg);
System.out.println(res);
System.out.println("========================================================================================");
System.out.println(Arrays.toString(msg));
System.out.println("========================================================================================");
byte[] bytes = ISOUtil.hex2byte(res);
System.out.println(Arrays.toString(bytes));
System.out.println("========================================================================================");
printISOMessage(resIsoMsg);
System.out.println("========================================================================================");
ISOMsg iso = new ISOMsg();
iso.setPackager(packager);
iso.unpack(bytes);
iso.dump(System.out, "");
System.out.println("========================================================================================");
return isoMsg;
}
private void printISOMessage(ISOMsg isoMsg) throws org.jpos.iso.ISOException {
System.out.printf("MTI = %s%n", isoMsg.getMTI());
for (int i = 1; i <= isoMsg.getMaxField(); i++) {
if (isoMsg.hasField(i)) {
System.out.printf("Field (%s) = %s%n", i, isoMsg.getString(i));
}
}
}
public static void main(String args[]) throws ISOException, IOException, org.jpos.iso.ISOException {
SimpleClient s=new SimpleClient();
s.sendData();
}
}
and the response class
public class Response {
private Map<String, Object> dataFields = new HashMap<>();
public Map<String, Object> getDataFields() {
return dataFields;
}
public void setDataFields(Map<String, Object> dataFields) {
this.dataFields = dataFields;
}
}
but i have a problem, if we would like to set subfields for field 40 for instance, how can we set them and integrate them in the ISOMsg object to send?
UPDATE : here is my packager :

Answer
Its failing as its trying to set the bitmpap field -1
If you don’t have a bitmpap for DE48
Define your DE48 as the following with emitBitmap to false
<isofieldpackager id="48" emitBitmap="false" length="999" name="RESERVED PRIVATE USE" class="org.jpos.iso.IFA_LLLCHAR" packager="org.jpos.iso.packager.GenericSubFieldPackager">
<isofield id="1" length="999" name="Additional data - private" class="org.jpos.iso.IFA_LLLCHAR" />
</isofieldpackager>
Sample test code
public static void main(String[] args) throws ISOException {
ISOMsg m = new ISOMsg("0100");
GenericPackager pkg = new GenericPackager("path to packager");
Logger l = new Logger();
l.addListener(new SimpleLogListener());
m.setPackager(pkg);
m.set("48.1","ABCD");
byte[] arr = m.pack();
m.unpack(arr);
m.dump(System.out, "");
}
Since we do pack and unpack we ae sure that the data is being being handled correctly.
output
<isomsg direction="none">
