cannot find control data "0x0D" using isoMsg.getString(id) method

[jsmith]

Hi all,

I need to get the value of a field of type org.jpos.iso.IFB_LLNUM.
I used isoMsg.getString(field_id), It works fine but this field is
sent with a control character 0x0D that split this field into two
parts, I need to query this filed by this control character.

Please help me how to find this character from the returned string.

Thanks.

string.indexOf('\015'); ?

I've tried
string.indexOf('\015');
string.indexOf('\013'); , etc
but the problem appears as when i print the contents of this string it
prints equal sign instead of 0x0D character !!

[jsmith]

The value from the hexdump:
4041000000000001D0534534534112342340000

while while i looped on the output of getString(field_id), I get :
4041000000000001=0534534534112342340000

the getString() method has replaced 0x0D by =

please help

It is treating it as a track 2 field...

... perhaps not always desirable. I thought just recently that moving
this translation behaviour to a dedicated field class could be good, but
have not done anything about it yet.

Can you just find the "=" instead?

There isn't any way to find 0x0D character ??!

Can you share the output of ISOUtil.hexdump()

Find a value in a *String* that doesn't contain it...
...no.

You could probably look for your x'0D' in :-

byte[] value;
value = isomsg.getBytes(35);

...but you would have to try it. The field is trying to be 'helpful'
and uses = to represent the BCD 'D' value...
... it might not always be 0x_D you are looking for, it might be 0xD_
(where 0x indicates hexadecimal), depending on the length of the PAN or
whatever precedes the separator.

May I suggest again you use ISOMsg.getString(35) and then find the "="
instead of the 'D'?

You are - I assume as you show no code - asking for a String of the
binary field? The conversion works for some, but not for your need it
seems.

I do think this behaviour should be separated out...

... perhaps I will get around to it next year.

I'll go with "="
Thanks.
