Hi ,
We are having an integration appln , sits between say A and B... the interface to both is MQ. I am using mq jms to connect my appln to both the queues.
But when the messages reach the end system, B, the MQFRMT is "" (blank) in the message header. I was expecting it to be MQSTR.
I have set TARGCLIENT(MQ) for the queue to B... but still its going to B with blank message format becoz of which their application is not able to pick messages...
any help for resolving this?
Regards,
Atheek

Are you sending a TextMessage?

| we're sending a text message only..we're using weblogic foreign jms setup to connect to the queue . Is there any jms object I need to configure for ensuring messages go to the target with format MQSTR? |

Yes you need to use a javax.jms.TextMessage to send a message with format MQFMT_STRING.

thanks saper. We are using aqualogic service bus (alsb) and in that for a business service we have used a MFL as a request type. I think that is causing the problem..we need to change this to text , I believe.
One more clarification:
our appln is in windows and B is in AIX...as a result there will be differences in CCSID's and encodings.
we are sending the message with mqmd ccsid set to 273 (windows) and encoding = native. when this reaches AIX queue manager , will it automatically do the conversion to its ccsid and encoding ? or the receiving appln needs to do anything ? ( i read sumwhere it shud use convert option in mqget call...is this reqd?) And is it required to set MQMD format to MQSTR if this conversion has to take place?
I am also using an alsb proxy service to read from a queue using foreign jms....to enforce this convert option, any idea wher I need to configure

thanks vitor...but still anyone can tell why the mqfmt is blank...we're using text/UTF-8 encoding in the ALSB business service..does this "UTF-8" have anything to do for this issue(format field blank)???
TIA

Possibly. If it uses the java native interface and does a writeUTF than the only correct way is to read the message with readUTF...
The standard here should be to declare the qcf with ccsid 1208 (UTF-
This would ensure that the messages are UTF-8 on the queue. The format should be MQFMT_STRING (using javax.jms.TextMessage)...
When you read them use get with convert.
Enjoy

one more clarification:
if using convert option does the data conversion then, when does crtmqcvx come into picture??  |

I believe this comes into the picture when you need to create an additional conversion table. Say the conversion from CCSID A to CCSID B is not supported but the conversion from CCSID A to CCSID C and CCSID C to CCSID B is supported.
Now you need to create a new mapping from CCSID A to B and B to A.
You know what maps where and need to create the map. I believe that this command means create mq conversion map/table....
Enjoy
