dynamic delete queues using the Java client?
Hi,
I understand that the JMS client allows createQueue() dynamically. Is
there also a way to delete a queue dynamically at run time?
My use case is primarily towards test environments. There are a lot of
queues created in context of various tests, I'd like to clean them up than
leave them behind.
Thanks,

Thanks for the mail Robbie.
Delete on receiver session close sounds reasonable for my use case.

The Qpid clients offer an extension (JMS deliberately doesnt actually
offer a way to create or delete non-temporary Queues:
Session.createQueue doesnt actually create queues at all, and just
returns reference objects to Queue identities) whereby a
consumer/producer can actually create and delete queues on the broker
at the point of being created and closed respctively, when specified
via the Address strings
(http://qpid.apache.org/books/0.12/Programming-In-Apache-Qpid/html/ch02s04.html).
Thus one way to accomplish what you want would be to use a
consumer/producer with an appropriately crafted Address string to do
the delete when they are closed. Alternatively, depending on how you
use the queues you might insead make use of auto-delete queues, which
get deleted when the session is closed. Finally, the Java broker has a
JMX interface and the C++ broker a QMF interface which you can use to
manage the queues.
