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

[timfox]

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.
