             Summary: Queue's not supposed to be durable
                 Key: JBMESSAGING-1953
                 URL: https://issues.jboss.org/browse/JBMESSAGING-1953
             Project: JBoss Messaging
          Issue Type: Feature Request
          Components: JMS Destination Manager, Messaging Core
            Reporter: Theo Burden


Feedback on https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Fuse/6.0/html/Implementing_Enterprise_Integration_Patterns/files/MsgEnd-Durable.html

I want to point out what looks to me as a discrepancy.

I have experience with various JMS messaging systems. The standard as I understands it is:

Queues - the first subscriber that are able to receive the message will get it and only one subscriber.  This normally makes queues by default durable as messages will stay on the queue till it has been received. 

Topics is by default non-durable as a registered subscriber is needed to receive the message. If the subscriber is off-line for some reason the message will be deleted, unless it is marked as durable. As soon as all subscribers have received the message it will be deleted. This I know as I developed systems that made use of this functionality.

This is also stated in the JBoss_Enterprise_Application_Platform-6-Administration_and_Configuration_Guide-en-US on page 287. It is also in the above mentioned web-doc.

In the JBoss training and in the Admin Console, this is contradicted as the Durable option is only listed under the Queues page and not under the Topics page. This does not make any sense as stated before. I am about to write the EX248 exam and it bothers me that I have to use a feature incorrectly and in a non-standard way.
