Hi,
I want to set up MessageID specifically(not the auto generated one) using JMS. How?
I can use Java client code like :
| Code: |
int openOptions = MQC.MQOO_OUTPUT | MQC.MQOO_SET_IDENTITY_CONTEXT;
pmo.options = MQC.MQPMO_SET_IDENTITY_CONTEXT | MQC.MQPMO_SYNCPOINT;
mqMsg.messageId = messageID.getBytes(); |
By using JMS, I use below code, how ever, it doesn't set up properly.
| Code: |
| jmsmsg.setJMSMessageID(messageID); |
|

| I don't think you have the option to set the JMSMessageID. If you'll look at chapter 12, you'll see that it is set by the provider (ie, MQ) at send time. |

Hi Ron, I don't really know why... (probably because I am not a Java/JMS literate) but the way I read that part was in the send method you can set JMSMessageID.
So now I understand that these JMS fields are filled after you have called the method...
Although not of direct use to me, thanks for making me understand it correctly

However, if I use Java client, I can set the message ID like:
| Code: |
| mqMsg.messageId = messageID.getBytes(); |
Does not JMS provide the same funtion? |

| JMS provides the function that is specified in the specification. There are things that the base MQ product will allow you to do that are not in the JMS spec. |
