Purge queue

Question

is there a way to purge a queue or topic of all messages from the command line? In other words, is there a way to delete all the existing messages already in an existing queue or topic?

Answer 1

From the command line, I am sure there is a command within the runmqsc command. But I am not sure what it is..
Through a program you could just do destructive reads with a receiver that does a "GetWait" on the queue.
//Start session and etc....
          QueueReceiver queueReciever = session.createReceiver(Queue object);
          boolean messagefound = true;
     //Start connection
          connection.start();
          while (messagefound) {
Message m = queueReciever.receive(1000);
if (m != null) {
messagesCleared++;
}else {
messagefound = false;
//Close session and connection once all messages have been read off.
     session.close();
     connection.close();
