how to store jms messages until clients come online ?

[raminaa niilian]

Hi
Thank you for reading my post
I know that i can use a pub/sub model to send a message to several subscriber , and a point-to-point to send message to a queue and then a client will fetch the message .

now i need to have :

Messages should stay in the queue until a clinet come and fetch them , even if it tale several days.

how i should configure the queue for this kind on requirement ?
how i should make sure that message will not lose on a server failure ?

does pub/sub support such kind of messaging ?

Thanks

You should not have to do anything.

JMS messages are PERSISTENT by default ("Delivery Mode") (per the spec I think).

With JMS, a discussion of pub/sub versus point to point is not relevant: see the MessagProducer interface, and the QueueSender and TopicPublisher implementations.

Look for "Durable Subscription" to messages in the docs.
