Hi there,
I have messages with an RFH Header created by a Java Programm. Can somebody point me to the C example to read out the messages _without_ the RFH-Stuff. Is it an MQ Option ? I am using a Simple MQGET - Call as described in the examples.
Kind regards

No, it is not a WMQ option.
Once you get the msg, read the StrucLength from the RFH header. The next part of the msg starts at that offset into the whole msg.

Like this 
| Code: |
/* check the message format for an RFH */
if ((memcmp(msgdesc.Format, MQFMT_RF_HEADER, sizeof(MQFMT_RF_HEADER) - 1) == 0) ||
(memcmp(msgdesc.Format, MQFMT_RF_HEADER_2, sizeof(MQFMT_RF_HEADER_2) - 1) == 0))
{
rfhlength = checkRFH(msgdata, datalen, &msgdesc);
}
/* and then */
fwrite(msgdata + rfhlength, datalen - rfhlength, 1, outFile);

This is strange. How can theses JavaGuys include their stuff in the MessageBody.
Anyway I have filtered it with :
| Code: |
jms_crap = "</jms>"
jmspos = mqmessage.find (jms_crap)
if jmspos >= 0:
encoded = mqmessage [jmspos + len (jms_crap):].lstrip ()
|
Cause "</jms>" plus some blanks is the last stuff
Kind regards

Not always. It depends on the length of the data in the last "folder".
Cheers,

I know the stuff that has to come after </jms> I will check for it and raise an exception if I did not see what I expect.
Kind regards
