messageQueue.factory.getConsumerFor

# NORMALLY, this url would be of the form 'tcp://host:61616', but for testing, activeMQ provides
# a local/internal queue that works by default
queueUrl <- "vm://localhost?broker.persistent=false"

# create a queue consumer
queueAconsumer <- messageQueue.factory.getConsumerFor(queueUrl,"queueA","activeMQ")

# ... do some stuff ...

# close the consumer
status <- messageQueue.consumer.close(queueAconsumer)
