Hi,
I am running a JAVA program which needs to take the correlation Id from the message header and put it back into another queue.
I have declared a MQMessage object 'message and that is able to put the message,if i assign a sting to it......
But the problem is i'm not able to get the correlation Id from the message itself ????
Could some one tell me the API |

You are sure that you are not supposed to take the MESSAGEID of the incoming message and put it into the CorrelationID field of the outgoing message ?
Enjoy  |

You should be able to just set your new id based on what your old id is. For example, something like:
| Code: |
MQMessage msg = new MQMessage(); /* get a new message */
MQPutMessageOptions pmo = new MQPutMessageOptions(); /* get a new PMO */
pmo.options = MQC.MQPMO_NEW_MSG_ID | MQC.MQPMO_NEW_CORREL_ID; /* we want new msg, correl id's */
qServer.put(msg, pmo); /* put the message */
MQMessage msgReply = new MQMessage(); /* get a new message */
msgReply.messageId = msg.messageId; /* copy the put message id to the new message's message id */
|
And, I suspect that fjb_saper is right about what you want to do. The normal pattern is to reply to a message and move the incoming message's message id to the outgoing message's correlation id. |
