Building XML in field 127.22 on Postilion

[Foly]

I am having a an issue with the packing of sub-field 22 of field 127 in postilion.

My sample implementation is as follows: 

field22 = "<ThirdPartyBillPayment>" +

                                    "<BillPaymentResponse>" + 

                                     "<ReferenceId>2222222222</ReferenceId>" +

                                    "</BillPaymentResponse>" +

                                  "</ThirdPartyBillPayment>";

inner.set(22,field22);

m.set (inner);

The issue is that postilion expects something like: 

 [LLLLLVAans 99999 00886] 127.022.ThirdPartyBillPayment
                                   [<ThirdPartyBillPayment>
                                       <BillPaymentRequest>
                                         <ReferenceId>1111111111</ReferenceId>
                                       </BillPaymentRequest>
                                     </ThirdPartyBillPayment>]

What I noticed is that 127.022.ThirdPartyBillPayment appears to have ThirdPartyBillPayment as another subfield.

Kindly assist as I do not know how to successfully implement this.

Thank you.

I have gone through the documentation and I seem to have a fair idea of what is required.

The problem I have is how to set additional subfield such as 127.22.ThirdPartyPayemnt using JPOS.

The documentation extract can be seen below:

ans..99999, LLLLLVAR

Description

This is a Postilion specific addition to the ISO 8583 standard.

This field uses a key/value pair structure to represent data. The idea behind the field is to provide a flexible mechanism with which to transport data through Postilion. There is therefore no limitation to what either the key or value may contain, provided of course that the format of the field is adhered to.

The physical layout of the field is as follows:

1 byte length indicator of the key length indicator

Length indicator of the key

Key

1 byte length indicator of the value length indicator

Length indicator of the value

Value

The table above describes the physical layout of a single key/value pair, it is therefore repeated for each key/value pair in the field. There is no limitation to the number of key value pairs that may be used, besides the overall field length.

Note: As of Postilion 4.0 service pack 5, this field is stored in the Postilion transaction table.

Postilion defines DTDs for the following:

• StatementData
• CardManagementUpdateData
• CardManagementUpdateLoad
• PrepaidMerchandise
• PurchasingCardData
• FleetCardData
• CheckData
• AirlineItineraryData
• VehicleRentalData
• LodgingData

XML that conforms to the structure described in the these DTDs is inserted into this field using a tag comprising the DTD name prefixed with the string Postilion:. For example, when inserting statement data in XML form, the key will be Postilion:StatementData and the value associated with it would be the well-formed XML that conforms to the StatementData DTD.

Postilion defines the following key/value pairs for use with this field.

Key	Description	Present in message
Postilion:UserDomain	The 'value' consists of the domain of the user currently logged in to the PostCard User Interfaces.	0320, 0322
Postilion:UserID	The 'value' consists of the ID of the user currently logged in to the PostCard User Interfaces.	0320, 0322

Foly,
So where are you setting the length in your

field22 = "<ThirdPartyBillPayment>" +

                                    "<BillPaymentResponse>" + 

                                     "<ReferenceId>2222222222</ReferenceId>" +

                                    "</BillPaymentResponse>" +

                                  "</ThirdPartyBillPayment>";

inner.set(22,field22);

m.set (inner);

I suggest look at their binary data (hexdump) , instead of their beautified traces :)

From the copyrighted docs and your sample on what it should look like in postilions trace, this is may work for you

field22_key = "221ThirdPartyBillPayment";
// 221 : 2 length of length (21), 21 length of "ThirdPartyBillPayment"
field22_value = "3125<ThirdPartyBillPayment><BillPaymentRequest><ReferenceId>1111111111</ReferenceId></BillPaymentRequest></ThirdPartyBillPayment>";

field22 = field22_key+field22_value;

Thanks a lot.
I will do that.

[Foly]

Chhil,

    Thanks a lot for the advice.

It worked as pointed out.

[chhil]

Good to know.
