When a queue producer is created, objects are created in the background and exist for the lifetime of that producer. Explicitly closing the producer safely deallocates memory and restores natural order to the world.

messageQueue.factory.getProducerFor

# 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 producer
queueAproducer <- messageQueue.factory.getProducerFor(queueUrl,"queueA","activeMQ")

# ... do some stuff ...

# put a message on the queue
textMessage <- "this is the message I want to send"
status <- messageQueue.producer.putText(queueAproducer, textMessage)

# close the producer
status <- messageQueue.producer.close(queueAproducer)
