Hi all,
We want to set the MQMD.Format from a java application running on WAS 8.5.5 using native JMS libraries and the Connection Factory and MQ resources managed by WAS:
| Code: |
TextMessage message = session.createTextMessage(xml);
...
message.setStringProperty("JMS_IBM_Format", "MQFMT_STRING");
...
|
The documentation says you need to set JMS_IBM_Format property to MQFMT_STRING, that internally will be mapped against the MQMD.Format field.
In WAS, in the queue configuration, the format property body is "MQ" and the reply is "MQMD".
We have made a lot of tests and combinations of these properties, but no success... In MQ, the format is always set as blank...
Have any of you a clue on how to set the format?
Any help is very appreciated.
Thanks in advance. |

Options to generate standard MQSTR messages from JMS application.
1. Set the output MQ queue name URI (sometimes called destination resource) like this (rather than having just the queue name) - don't code the brackets []
queue:///[THE.MQ.QUEUE.DEFINITION]?targetClient=1
-------------------------- or ---------------------------
2. In the program code - set the target client on the queue object to NON JMS.
q.setTargetClient(JMSC.MQJMS_CLIENT_NONJMS_MQ);
------------------- or ---------------
3. In the JNDI or properties - do the same as option 2 - I don’t know much about how to do this.
NB: MQJMS_CLIENT_NONJMS_MQ equates to the value 1
--------------------------------------
I would suggest option 2.

Thank you zpat for your reply.
For the second option, the setTargetClient method can only be used with com.ibm.mq.jms.MQQueue object... but.. we are not using at all com.ibm.mq.jms library... any workaround? |

So you are using JMS with probably a WAS type JNDI.
2 things are needed to achieve what you want to do.
- Define the message as a javax.jms.TextMessage i.e. use
Session.createTextMessage()
- Set the queue to use targetClient MQ.
You can either define that in the JNDI when you set up the queue
Or if using reading queue names from properties make sure you use the URI form:
String qname="queue:///QUEUENAME?targetClient=1";
Session.createQueue(qname);
If you are using pub/sub I would suggest that the application uses TextMessage and the receiving application codes for "properties in Handle" in order to not get an RFH2 header...
Have fun

Did you switch the destination from type JMS to type MQ? And verify that it took in the config file after save? Obviously you'll have to bounce the server for the new config to take effect...
