Dear all,

I am working on ISO8583 messages, as our client sent ISO8583 packed bitmap message but when i received on IIB Version 10.0.0.15 TcpInput Node message not parsed successfully. In debugging mode I have found that bitmap not parsed properly. I am using IBM Integration Bus ISO8583 schema named "ISO8583_1987.xsd".

I am receiving in Hex format of input message is:

While parsing this message on ISO8583_87 iam getting error

Quote:
fatal: CTDP3000E: Unexpected end of data at byte offset '68' while parsing element '#xscd(/schemaElement::ISO8583_1987/type::0/model::sequence/schemaElement::Track2Data_035)'. The parser encountered the end of the data stream or the end of a parent element.


Kindly let me know if i am doing anything wrong.

Thanks,
Hasan

The ISO8583 model assumes that the bitmaps are in binary. If you are receiving packed decimal bitmaps then you will need to parse as BLOB, do some manipulation to convert the bitmaps to binary, then reparse using the ISO8583 model.

Yes, I understand the problem. I was responding to this part of your problem statement:

ISO8583 bitmaps can be sent as packed decimal or binary. If yours are packed decimal then you will need to do some pre-processing as described in my reply.
