| I am using MQ JMS to write an application that uses triggered dynamic queues, and would like to know how to set the MQCA_PROCESS_NAME attribute for each dynamic queue to an existing process definition object. |

You are not going to be able to do that with JMS. JMS is designed for reading from, and writing to, queues. It's not designed as an administrative API.
But, the bigger question is, why do you want to trigger dynamic queues. There has to be another way to design your system. What are you trying to achieve.
Cheers,

My apologies, I meant the MQSeries Java API, not JMS - is there a way to set the ProcessName attribute for each queue?
Dynamic queues are being used to store messages belonging to different batches, with a depth trigger set to the batch size on each queue. When the queue is triggered (msgs on queue = size of batch), another program collates all the msgs on the queue into a file which is then submitted to another system. |

| SupportPac MS0B supplies the Java PCF classes which allow you to perform administration. |

As Ron has pointed out, the PCF classes are available in a Support Pac.
But, as well as the ProcessName, you'll have to set up all the other Triggering attributes as well. Your Triggered application will have to use the Trigger message to work out which Queue to read. And how are you removing the Dynamic Queues after you have used them.
Would it not be better to use a single Queue for these messages and associate the MessageID/CorrelationID with a batch. You could then send a single message to a Triggered Queue that contains the details, so the second application could just pull the required messages.
Cheers,
