Hi,
Im trying to integrate with Postillion and managed to send an 0800 message . However when trying to do a balance enquiry im getting an error. I have checked traces and found that field 127.22 has a subfield called MSDN and so on sample trace below
[LLLLLVAans 99999 219] 127.022.MSDN
[260979841847]

Please advise how i can implement this in jpos

Please tell us the specific error/ exception you are getting along with the packager you are using. If it's a custom packager please attach it.
We understand jpos, so non jpos trace logs don't help us in helping you.

Hi,
Im trying to create a subfield of field 127.22. The external Postilion interface is expecting it as 127.22.MSDN
Jpos error..

Hi,
I suggest using https://github.com/jpos/jPOS/blob/master/jpos/src/dist/cfg/packager/postpack.xml as your packager,as we know it works. Just be double sure by going through it to make sure.
On glancing through the difference I believe is that your packager has sub fields defined for some fields
that are a composite of a few fixed sub-fields.
Try postpack.xml that and if it works fix your packager. If you are still having problems provide a hex
(jpos)/binary(postilion) data dump of the 0800 message.

Hi,
Using postpack.xml you would do a isomsg.getString(127.22) to get the structured data. Then use your own POJO to extract the data from it. Structured data is some variation of [length of length][length][ tag ][value], see the postilion spec for its details, and it can contain many such LTV elements and in any order. You have mis-configured your pst.xml by having
<isofieldpackager id="22" length="99999" name="RESERVED PRIVATE USE2"class="org.jpos.iso.IFA_LLLLLCHAR"packager="org.jpos.iso.packager.ISO87APackager">
<isofield id="MSDN" length="99999" name="MSDN"class="org.jpos.iso.IFA_LLLLLCHAR"/>
</isofieldpackager>
The isofield element needs to be an integer and you have MSDN and hence it fails. Plus the packager has no understanding of the LTV substructures to extract and give you the data associated with it. That's something you would have to do in your code.
You can refer to https://groups.google.com/d/msg/jpos-users/zT7d5fzGEuQ/_f4pnBcZAkYJ to see a sample breakdown of a structured data field

When user an outer package (in this case field 22's isofieldpackager, it's a good idea to use a BINARY packager instead of CHAR, in this case IFA_LLLLLBINARY. Using LLLLLCHAR happens to work but uses a String conversion (that may involve i18n related issues easily).

What is not working?
Have you asked the Postilion side on what is wrong?
Have you looked at your Postilion spec and constructed your message as required?
You cannot put a snippet of code saying its not working. Currently only you know whats not working.

Hi from postilion side it’s complaining of invalid field length.Its failing to read field 127.22 sub fields

Hi,
String field22_value = "210260953104906";
String field22_value1 = "210260953104906";//"221MSDN";1....9 is 2 then 10....99
Length should be 12 and not 10 , so it should be
