Hi,

We have a sender and a receiver in a P2P communication model.
In case the sender is trying to send some data to the receiver, and the netork fails.

1. Will the sender be notified that the data packet is not received by the receiver.
2. Will the sender get an error saying that connection with the receiver failed.
3. How will sender check whether receiver is up or not ? Any particular method that will be used.

Thanks,
Deepak.

Acknowledgement would work. IF Acknowledgement is not received, it means failure.
I beleive AUTO_ACKNOWLEDGE, CLIENT_ACKNOWLEDGE, and DUPS_OK_ACKNOWLEDGE, any one would help

Sender sends data to the jms server, not the receiver. The jms server sends it out to the receiver.

>In case the sender is trying to send some data to the receiver, and the netork fails.

Change the question to the sender tries to send data to the jms server
And the answer for that is the message sending from client to the jms server itself is a synchronous call. The QueueSender.send() message will throw a JMSException if the message isnt posted to the server for some reason.

Does that answer your question?

Acknowldgement is on the receiver side. If the jms server does not receive an acknowledgement from the receiver that it has received a message, the message would be put back in the queue/topic. Whether it would be redelivered depends on a lot of other considerations.
