[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: Once and only once delivery?

I suppose "once and only once delivery" only really applies to the *delivery* of messages from a queue (or durable sub). It doesn't apply to sending a message to a queue. However, if it's not possible to write a client that can guarantee it hasn't sent the same message more than once to the same queue, then I'm trying to understand how useful that is. So here's the problem: Write a JMS client that sends 10 and only 10 messages to a particular queue on a remote server, with a client that consumes those 10, and only those 10 messages. Can anyone volunteer a solution? Right now, I can't see how that is possible in JMS without using 2PC. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977046#...
