Unpacking exception

[Fahimeh]

Hi.
I hope everything is ok for you.

When my client (POS device) sending data to server i got a exception.
I think the server couldn't unpacking data correctly.
I don't know why!
How can i solve this problem?!

That is the importent part of my server class:

/
***************************************************************************************/
ServerChannel channel = new NCCChannel(new ISO87APackager(), null);
((LogSource) channel).setLogger(logger, "channel");
ISOServer server = new ISOServer(3200, channel, null);
/
**************************************************************************************/


and the exception :

Add a Logger to your Packager and also make sure you have made sure your
packager (ISO87APackager) matches the structure of the message you are
receiving field for field.

Your packager is not aligned with the data element type.
Try to use your ISOMsg object and put field 51 and see what the dump
looks like and how it differs from the data you are receiving, this
should help you fix the format of that field.

I suspect it might be a field before 51 that is pushing things out of
alignment, but the advise given is by chhil and myself should help you
find it.

But please do check each field for a match to the interface
specification it will save you problems.
