Using TLVs
Prajakta S
I am working on ISO8583 version 2003 spec wherein some of the data
elements
have TLV format.
I have downloaded the "jpos-1.6.0-r2465" sourcecode from
sourceforge.There is a class TLVList which handles TLV type of data
elements.
I also referred to "http://en.wikipedia.org/wiki/Type-length-value" to
understand its meaning.
But in ISO v2003...the TLV is just the subelement..i.e the
eg Bit 43 - Card acceptor name.location if of type LLLLVAR ansb..9999,
it has subelement
43-71 - Card acceptor address information which is of type "Tag
81" ..
My question is does jPOS currently support this? Is the above element
to be treated as only "LLLLVAR ansb..9999" and TLV to be ignored?
Thanks,
Prajakta

71 image as another ISOMsg with a configuration similar to this:
<isofieldpackager

emitBitmap="true" bitmapField="0"
packager="org.jpos.iso.packager.GenericSubFieldPackager">
<isofield

name="Bit Map"
class="org.jpos.iso.IFB_BITMAP"/>
<isofield
id="2"
length="50"
name="Card acceptor name"
class="org.jpos.iso.IFB_LLCHAR"/>
<isofield

length="99"

<isofield

length="16"
name="Card acceptor phone number"
class="org.jpos.iso.IF_CHAR"/>
<isofield
id="9"
length="16"
name="Card acceptor customer service phone number"
class="org.jpos.iso.IF_CHAR"/>
<isofield
id="10"
length="30"
name="Card acceptor additional contact information"
class="org.jpos.iso.IFB_LLCHAR"/>
<isofield
id="11"
length="255"
name="Card acceptor internet URL"
class="org.jpos.iso.IFB_LLLCHAR"/>
<isofield
id="12"
length="99"
name="Card acceptor e-mail address"
class="org.jpos.iso.IFB_LLCHAR"/>
</isofieldpackager>
We hope to make this simpler in the near future. We want to push 1.6.2
out as soon as possible and this is a nice feature for 1.6.3.

How should we handle a complex data element like TLVs.
What I mean is with the XML configuration given below
how should we set the field value in ISOMsg object for composite
elements.
Usually we set it like-
m.set(3,"21");
How should composite elements like the one below be set?
Thanks,

For non-TLV composite elements, you can use code like this:
m.set ("63.1", "0000");
in order to set field 63's subfield 1.

ISOMsg has following set methods
set(int fldno, String value) and
set (int fldno, byte[] value)
So, m.set ("63.1", "0000"); will not work

problems with it),
Was this being handled in any other way in earlier version,or was it
that the concept of subelements was introduced in recent versions of
ISO8583 spec?
