Check if a Queue Exist in JMS Hermes Session

Hi

I am using groovy scripts to connect and browse JMS messages (have successfully published and consumed messages from the JMS queue using hermes JMS SESSION).

1. However I would like to validate if the queue exist in that SESSION using groovy script, refer to pseudo code below:
if (queueExist(queue_name) in SESSION TEST_SESSION)
log.info queue_name+"found"
else
log.info queue_name+"queue not found"

2. I would also like to be able list all queues available on a selected hermes SESSION e.g. TEST_SESSION, refer to pseudo code below:
hermes_session = TEST_SESSION

for (queues in TEST_SESSION)
{
log.info queues
}
