The plot thickens !

The below code resulted in the BLOB being set to empty.

Code:

SET mimePart .Data.BLOB.BLOB = ASBITSTREAM(refFileSet.PackedData CCSID 1208 ENCODING 273);

Quote:

(0x01000000:Name):Part = (
(0x03000000:NameValue):Content-Type = 'application/zip; name=application-logs.zip' (CHARACTER)
(0x03000000:NameValue):Content-Transfer-Encoding = '8bit' (CHARACTER)
(0x01000000:Name ):Data = (
(0x01000000:Name):BLOB = ( ['none' : 0x11d49a530]
(0x03000000:NameValue):BLOB = X'' (BLOB)
)
)
)
)
)
)

A question here is why should we use ASBITSTREAM function when the variable contains a BLOB which is a byte array ?
One more interesting point in this is that if I open the zip (empty looking one) in notepad, I can see the zip entries (file names in clear text) interspersed within the binary data.

Will try out using Base64 encoding and will report my findings.

If I remember correctly it has to do with encoding 8 bit vs 7 bit and UTF-8 settings. It is better to specify 64 bit encoding and do not forget to specify this also in MIME.

Hope it helps

Houston, we have a touch down ! Using the Base64 encoding worked. I now have a valid zip file delivered in my inbox !

Code:

CREATE FIELD mimePart."Content-Type" TYPE NameValue VALUE 'application/zip; name=application-logs.zip';
CREATE FIELD mimePart."Content-Transfer-Encoding" TYPE NameValue VALUE 'base64';

CREATE LASTCHILD OF mimePart TYPE Name NAME 'Data';
CREATE LASTCHILD OF mimePart.Data DOMAIN('BLOB') PARSE(BASE64ENCODE(refFileSet.PackedData) CCSID 1208 ENCODING 273);

Thank you fjb_saper, mqjeff, Vitor ! I bow to thee !
