Error Packing Field 52

[ola]

Hello,

Thanks all these while for your supports! I really appreciate you
guys.

I am having issue packing field 52 (PIN BLOCK). I have a JPOS
application that connects to Postilion Server, which is working fine,
but I need to introduce PIN security. Right now, I can do key exchange
(get working key using master session) from the Postilion, which I
used to generate hexadecimal 16 xters PIN BLOCK (e.g.
FAA57088694EF194). The problem is that JPOS could not pack this field
by throwing an exception below:

<iso-exception>
org.jpos.iso.IFA_BINARY: Problem packing field 52
....

I am using postpack.xml for my packager as seen below:

Logger logger = new Logger();
logger.addListener(new SimpleLogListener(System.out));
ISOPackager p = new GenericPackager ("cfg/
postpack.xml");
p.setLogger (logger, "test");
ClientChannel channel=new PostChannel("10.64.10.30",
6308,p);

pinblock=new GetPinBlock();
mux = new ISOMUX(channel);
....

Part of the logger message is shown below:

The short answer is :-

You are passing a String as a value to a field that is expecting a
byte[]. Looking at the code that is throwing this exception gives you
that detail.

The long answer is:-

The Exception trace is not too good to us, your version of these classes
does not match that in the repository. I can understand why it might be
different, but you need consider your changes when seeking help here.

To be certain of what your problem is...

We would need to see:-

your code from ISOMSg creation through to and including the code that
sets field 52.

It would also not do any harm to show us the definition of field 52 in
the packager xml file. As you have changed code, you might also have
changed postpack.xml.

If you are setting a packager (via ISOMsg.setPackager) then you might
benefit from a helper conversion from String to byte[]. If not (the
likely case here), you need to pass the right data in otherwise as you
see, problems will occur (GIGO).

You see the data in hex (16 bytes), but you probably want to send 8
bytes. Use m.set (52, ISOUtil.hex2byte ("FAA57088694EF194") to
solve your problem.

[Alejandro Revilla]

And BTW, this message doesn't have a field 0 ... weird..

PS.- I hope that's a test card.

The packing was successful after i used m.set (52, ISOUtil.hex2byte
("FAA57088694EF194"), but the challenge it introduced is that
postilion could not unpack my message again. When i compared the
packed message dump sent from my JPOS application (the field 52 was
converted to 16 hex characters: 46 41 41 35 37 30 38 38 36 39 34 45
46 31 39 34) with what postilion was expecting (type as b8),
postilion was unable to pack the message. Please, is there a way to go
about this so that the dump value for field 52 will be b8:
Like i said earlier, I used the packager below:

ISOPackager p = new GenericPackager ("cfg/
postpack.xml");

ClientChannel channel=new PostChannel("10.64.10.30",
6308,p);

My postpack.xml is shown below:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE isopackager SYSTEM "genericpackager.dtd">

<!--
