Subject Re: [activemq-user] How to achive Persistence for CMS
Date Thu, 29 Jun 2006 12:43:04 GMT
BTW the codehaus lists are no longer used.

If you use a queue rather than a topic then messages wait around until
a receiver comes back again.

I you are using a topic then messages are only dispatched from the
point of the subscription. However you can use persistent
subscriptions (and persistent message delivery) to ensure that
messages published while your consumer was down will be delivered when
your subscriber starts again.

It looks like CMS could do with a new method

  createDurableSubscriber(Topic topic, String subscriberName)

to create durable topic subscriptions. I've reaised a JIRA for this

BTW we might wanna make the CMS API polymorphic like JMS 1.1 is -
adding createConsumer/createProducer methods to Session - I created a
JIRA for that too...
