When i try to unpack this message :

723A4001088180001623334444555566663800990000000000000725090909100001090909072507306011040001ab9999999999ab9999999999999016000008389999999936003110

Using this code :

ISOMsg msg = new ISOMsg();
       msg.setMTI("0200");
        msg.setPackager(packager);
        msg.unpack(message.getBytes());
        formattedLogISOMsg(msg);

I get this following Error :

How to fix that? What i miss?
Please help, thank you very much.

A message starting with 723A doesn't seem like a valid ISO-8583 message. 

Please note you don't have to set the MTI on a message you are unpacking, the "0200" should be part of the message. Perhaps that 723A... is the bitmap and you just need to pre-pend the MTI (0200) to your message.

Hmm i am not sure where is the correct ISO message format.
But i try again create pack and unpack using this code :


PackISOMessage,java

public class PackISOMessage {
    public static void main(String[] args) {
        PackISOMessage iso = new PackISOMessage();
        try {
            String message = iso.buildISOMessage();
            System.out.printf("Message = %s", message);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public String buildISOMessage() throws Exception {
        try {
            GenericPackager packager = new GenericPackager("packager/iso93ascii.xml");

            ISOMsg isoMsg = new ISOMsg();
            isoMsg.setPackager(packager);
            isoMsg.setMTI("0200");
            isoMsg.set(1, "723A400108818000");
            isoMsg.set(2, "2333444455556666");
            isoMsg.set(3, "380099");
            isoMsg.set(4, ISOUtil.zeropad(350000, 12));
            isoMsg.set(7, "0725090909");
            isoMsg.set(11, "100001");
            isoMsg.set(12, "090909");
            isoMsg.set(13, "0725");
            isoMsg.set(15, "0730");
            isoMsg.set(18, "6011");
            isoMsg.set(32, "0001");
            isoMsg.set(37, "ab999999999999");
//            isoMsg.set(39, "00");
            isoMsg.set(41, "ab999999999999999");
            isoMsg.set(41, "ab999999999999999");
            isoMsg.set(48, "83899999999");
            isoMsg.set(49, "360");
            isoMsg.set(63, "110");
            printISOMessage(isoMsg);

            byte[] result = isoMsg.pack();
            return new String(result);
        } catch (ISOException e) {
            throw new Exception(e);
        }
    }

    public void printISOMessage(ISOMsg isoMsg) {
        try {
            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));
                }
            }
        } catch (ISOException e) {
            e.printStackTrace();
        }
    }
}

And the packed result is :
0200F23A400108818002162333444455556666380099000000350000072509090910000109090907250007306011040001ab999999999999ab9999999999999990118389999999936003110

I decide to unpack that message using this code :

UnpackISOMessage.java

public class UnpackISOMessage {
    public static void main(String[] args) {
        UnpackISOMessage iso = new UnpackISOMessage();
        try {
            ISOMsg isoMsg = iso.parseISOMessage();
            iso.printISOMessage(isoMsg);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public ISOMsg parseISOMessage() throws Exception {
        String message = "0200F23A400108818002162333444455556666380099000000350000072509090910000109090907250007306011040001ab999999999999ab9999999999999990118389999999936003110";
        System.out.printf("Message = %s%n", message);
        try {
            GenericPackager packager = new GenericPackager("packager/iso93ascii.xml");
            ISOMsg isoMsg = new ISOMsg();
            isoMsg.setPackager(packager);
            isoMsg.unpack(message.getBytes());
            return isoMsg;
        } catch (ISOException e) {
            throw new Exception(e);
        }
    }

    public void printISOMessage(ISOMsg isoMsg) {
        try {
            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));
                }
            }
        } catch (ISOException e) {
            e.printStackTrace();
        }
    }
}

I still get this following error :
java.lang.Exception: org.jpos.iso.ISOException: org.jpos.iso.IFA_LLNUM: Problem unpacking field 2 (org.jpos.iso.ISOException: Field length 66 too long. Max: 16) unpacking field=2, consumed=36

Don't set/touch the bitmap - there is no need and I think it might be
breaking the bitmap handling because you don;t need to touch the bitmap
- jpos sorts that out for you.

Here you can see that the bitmap is only eight bytes (F23A400108818002 -
followed by your 'PAN'), but the first bit is on indicating that it
should be 16, this likely pushes the alignment out and breaks the
conversion.

This bitmap issue is confirmed by the length of the PAN being found as
'66' - but this is within the PAN at the end of where the bitmap should
really end.

Adding a Logger to Packager will confirm completely what data is going
where.


> What's wrong?

Try not setting the bitmap manually first; also add a Logger to the
Packager to see the data splitting out.

Search the mailing list for the bitmap handling - it is described
multiple times, but first please stop manually setting the bitmap - that
is bad :-)

In addition to Mark's suggestion, please note that you have some errors in the field lengths you're building, in particular field 37 has a max value of 12 (you're trying to set 14 bytes), same goes for field 41, it's 8 bytes max.

If you correct those, you should see something like this:

"0200723A40010881800216233344445555666638009900000035000007250909091000010000000909090725000730601104000199999999999900      01183899999999360003110"

that of course unpacks cleanly.

Hi Fadi,

Please am having the same error, right now, can you help with how you fix yours?
See error:  unable to unpack field2
 org.jpos.iso.IFA_LLNUM: Problem unpacking field 2 (org.jpos.iso.ISOException: Field length 61 too long. Max: 19) unpacking field=2, consumed=20
Any help will be appreciated.

Usually this error occurs becuse the user has not implemented the packager correctly.

  1. Make sure you have accounted for the header (length and any other) if any.
  2. Make sure your bitmap packager is set appropriately.
  3. Make sure you field 2 packager is correct.
The first 2 will cause the byte reading to get offset causing mayhem.

Your packager and the one you use online are not aligned i.e. you have not defined the fields as expected by the online site.

You should go field by field and make sure you have defined them as expected by the online url you are trying with.


When I use the packager you have and unpack the message it works so there is no issue from a jpos perspective. This was packed using jpos so the pack and unpack work fine.

import java.io.IOException;
import java.net.MalformedURLException;

        Logger l = new Logger();
        l.addListener(new SimpleLogListener());
        packager.setLogger(l, "jsagfj");

        ISOMsg m = new ISOMsg();
        m.setPackager(packager);

        try {
            m.unpack("010072300000000000001642896976489287520200000000000050000515155540123456155540".getBytes(ISOUtil.CHARSET));

Hi Chhil,

Thanks for the clarification,actually I am new to this JPOS world.

Now I am getting  below error while unpacking the binary ISO message.

A bitmap message (postilion.realtime.postbridge.Iso8583PB) could not be unpacked, because of an error while unpacking field number 2 (LLVAR  n    ..19) at offset 12. When the error occurred, the bitmap looked like this:

0100:

I have used below code to pack the ISO Message.


GenericPackager packager = new GenericPackager("src/main/resources/basic.xml");
       

        ISOMsg isoMsg = new ISOMsg();
        isoMsg.setPackager(packager);
        isoMsg.set(0, "0100");

        isoMsg.set(2, "4289697648928752");
        isoMsg.set(4, "000000020000");
        isoMsg.set(3, "000000");


        isoMsg.set(7, new SimpleDateFormat("MMddHHmmss").format(new Date()));

        isoMsg.set(11, "105790");
        isoMsg.set(12, new SimpleDateFormat("HHmmss").format(new Date()));
        isoMsg.set(13, "0326");
        isoMsg.set(14, "2407");
        isoMsg.set(18, "5691");
        isoMsg.set(22, "012");
        isoMsg.set(25, "08");
        isoMsg.set(32, "454899");
        isoMsg.set(37, "908507105790");
        isoMsg.set(41, "00050041");
        isoMsg.set(42, "027174         ");
        isoMsg.set(43, "COMMERCIAL8360DubaiAEAE");
        isoMsg.set(49, "784");
        isoMsg.set(123,"100030104000000");
        isoMsg.set("127.010", "222");

        byte[] bIsoMsg = isoMsg.pack();
        System.out.println(ISOUtil.hexdump(bIsoMsg));

Your ISOMsg.unpack(..) takes a byte array.
Take the hex, remove the spaces and use ISOUtil.hex2byte(String...) to get a byte array and pass it into your ISOMsg's unpack method.

Write your own hexdump method that removes the standard very helpful byte offset column in the left and the helpful displayable data on the right. 

Or write a method that can parse the jpos hexdump to your liking to extract data.

Lovely decodeHexDump, I'll file a PR to use StringBuilder.

Jokes aside, can I trade a jPOS Sticker for that method to be added to ISOUtil?

no need for StringBUilder if using Collectors.joining()

public static byte[] decodeHexDump(String s)
{
    return ISOUtil.hex2byte(
            Arrays.stream(s.split("\n"))
                    .map(x->
                            x.replaceAll("^.{4}  ", "")
                                    .replaceAll("\\s\\s", " ")
                                    .replaceAll("(([0-9A-F][0-9A-F]\\s){1,16}).*$","$1")
                                    .replaceAll("\\s","")
                    ).collect(Collectors.joining())

    );
}

Lambda duel.

Awesome, we just need to use `System.getProperty ("line.separator");` instead of `\n` or figure out how to handle both and we'd be all set.

Now I feel ashamed for not polishing the little method I whipped in 3 minutes :(

Revised method:

    public static byte[] decodeHexDump(String s)
    {
        return
 ISOUtil.hex2byte(
            Arrays.stream(s.split("\\r\\n|[\\r\\n]"))
