I want to read a message of a queue but the queue name is allocated at run time. Basically my flow at present has: Input Node -> Compute Node (Request and Response Queue Names are External Variables) -> Output Node (Queue set to Request Queue (Destination List). Now I wanted to connect it to an MQGET Node OR Input Node but the queue names are mandatory fields, I want the queue name to be configurable to the Response Queue.
Basically I put to a message on the Request queue and then wait and pick a message from the Response queue.

Use MQGET node... you can set the queue name in the LocalEnvironment variable...

This is true, my only concern is that you may hang the thread indefinatly, or if a timeout occurs you must code in additional logic to handle this. |

Added a Compute Node before the MQGet Node and added:
OutputLocalEnvironment.MQ.GET.QueueName = Environment.Variables.ResponseQueue;

| This is what I have long feared - the addition of Java function to WMB is encouraging Java coding when it is absolutely not required. |
