ISOMsg

[saple]

Hi guys, I've been wondering w/c one is the correct way of converting
hex strings into byte array?

String str =
"0330303801000A8000009430000000000093350824192218130415018630343135323231383133313930303131303731333338";

ISOMsg isoMsg = new ISOMsg();
isoMsg.setPackager(packger);

--> isoMsg.unpack(str.getBytes());
or
--> isoMsg.unpack(ISOUtil.hext2byte(str));

isoMsg.dump(System.out, " ");

And what are the difference between the the two? Thank you so much.

Nope, unless you want the bytes of each of those characters.

Nor this, it won't compile (typo).

You want to :-

isoMsg.unpack(ISOUtil.hex2byte(str));

>

first returns the byte[] of each character, the second returns the
byte[] created by consider each *pair* of digits as *hexadecimal* and
then forming a single byte for each pair.

Of course what you actually want to do is tell us what packager you are
using and if it expects *binary* or *ascii* character data as input to
it's unpack method.

I have *highlighted* each word you might want to search and find out about.

I don't mean for you to search for *pair*, that highlight was for
emphasis only.

Thanks for the response.

This is the packager that I am using

GenericPackager packager = new GenericPackager("iso87ascii.xml");

isoMsg.unpack(ISOUtil.hex2byte(str));

when I try to run this code, I got this kind of error

error unpacking field 2

what is wrong with this packager? This is a sample message from an EDC

does jPOs have a packager that is made specially for EDC messages?

Thank you

I don't know if this packager matches your EDC terminal message
structure, but I do know that the packager is expecting ascii characters
and not binary as it uses IFA, so you can drop the hex character to
binary conversion...

ISOMsg isoMsg = new ISOMsg();
isoMsg.setPackager(packger);

isoMsg.unpack(str.getBytes());
isoMsg.dump(System.out, " ");

*But* I think you might have the wrong packager completely and you have
an extra byte at the start.

This is for you to decide - you should have the EDC message spec;
picking or making one is very easy and is your first step?

Is the message an ISO8583 structure:-
"0330303801000A8000009430000000000093350824192218130415018630343135323231383133313930303131303731333338"
?

what is the '03' at the start an STX perhaps?

Your MTI is not 4 bytes, but 3 - looks like "008" - unless you have
swapped the first two digits; which would give you "0008"

How long is your bit map?

All questions you need to consider the answers for.

I also think this sample is a 'hex dump' of a ascii-character/binary
message, so you need to determine what your raw message looks like (so
you can get a packager) before proceeding.

This sample has - I think been formatted for a human, so is no good for
'testing' unless you can accurately restore it to it's raw state before
unpacking.

Find out what the abbreviations mean this will help you pick or form a
packager.

No PAN (field 2) in this message then? That would explain why I can't
