Server not getting the complete subfields in my field 127

[Joseph Okonji]

Hi

I'm working on a kotlin code. I'm sending my request successfully to the server, my logs shows that all fields and subfields were included. The the server does not receive all the subfields.

Here is what my field 127 looks like in a modified iso87ascii.xml file;

<isofieldpackager id="127" name="ICC Info" length="999999" class="org.jpos.iso.IFA_LLLLLLBINARY" packager="org.jpos.iso.packager.GenericSubFieldPackager" bitmapField="0">

<isofield id="0" length="16" name="Bitmap" class="org.jpos.iso.IFA_BITMAP"/>

<isofield id="2" length="32" name="Subfield 127.2" class="org.jpos.iso.IFA_LLCHAR"/>

<isofield id="3" length="48" name="Subfield 127.3" class="org.jpos.iso.IF_CHAR"/>

<isofield id="13" length="17" name="Subfield 127.13" class="org.jpos.iso.IF_CHAR"/>

<isofield id="20" length="8" name="Subfield 127.20" class="org.jpos.iso.IFA_NUMERIC"/>

<isofieldpackager id="25" length="999999" name="Subfield 127.25" class="org.jpos.iso.IFA_LLLLLLBINARY" packager="org.jpos.iso.packager.GenericSubFieldPackager" bitmapField="0">

<isofield id="0" length="16" name="Bitmap" class="org.jpos.iso.IFA_BITMAP"/>

<isofield id="2" length="12" name="AmountAuthorized" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="3" length="12" name="AmountOther" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="5" length="4" name="ApplicationInterchangeProfile" class="org.jpos.iso.IFA_LLCHAR"/>

<isofield id="6" length="4" name="ApplicationTransactionCounter" class="org.jpos.iso.IFA_LLCHAR"/>

<isofield id="12" length="16" name="Cryptogram" class="org.jpos.iso.IFA_LLCHAR"/>

<isofield id="13" length="2" name="CryptogramInformationData" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="15" length="6" name="CvmResults" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="18" length="36" name="IssuerApplicationData" class="org.jpos.iso.IFA_LLCHAR"/>

<isofield id="21" length="6" name="TerminalCapabilities" class="org.jpos.iso.IFA_LLCHAR"/>

<isofield id="22" length="3" name="TerminalCountryCode" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="23" length="2" name="TerminalType" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="24" length="10" name="TerminalVerificationResult" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="26" length="3" name="TransactionCurrencyCode" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="27" length="6" name="TransactionDate" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="28" length="2" name="TransactionSequenceCounter" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="29" length="2" name="TransactionType" class="org.jpos.iso.IFA_NUMERIC"/>

<isofield id="30" length="8" name="UnpredictableNumber" class="org.jpos.iso.IFA_LLCHAR"/>

</isofieldpackager>

<isofield id="33" length="4" name="Subfield 127.33" class="org.jpos.iso.IFA_NUMERIC"/>

</isofieldpackager>

What am I doing wrong?

Thank you

You need to ask a smart question - http://www.catb.org/esr/faqs/smart-questions.html#intro

What processing is in Kotlin?

Check the bitmap handling since that drives what fields are 'present'.

Your smart question should included all the needed details, but on a java (primarily) jPOS mailing list, I am unsure why you would be using Kotlin and seeking help here.

I would guess that there is a mismatch in the packager and or channel, and thus the server not correctly interpreting the bitmap.

The other possibility would be the code for sending the message being wrong, but since you didn't share it we can't know.

How do you determine this? Does the jpos generated q2 log have the channel log with te message being sent? Or are you dumping the isomsg you created ?

Can you simply populate the isomsg , call the pack on the message to get the byte array and then do an unpack on the byte array to populate a new isomsg and then dump it to make sure your data is correctly unpacked with all the data you initially set?

ISOMsg m = new ISOMsg();

try {

pkg = new GenericPackager("path to packager");

m.setPackager(pkg);

m.set(field1,value1);

m.set(field2,value2);

m.set(fieldN,valueN);

byte[] packed = m.pack();

m.unpack(packed);

m.dump(System.out, "");

}

catch (ISOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

m.dump(System.out, "");

}

Just in case it helps, here is the JBang script I use to debug packagers: https://gist.github.com/ar/e5459490510e5d4547e4e3b6880c06cb

You can even run it remotely:
