Subject Re: Transactions in ActiveMQ
Date Mon, 25 Nov 2013 16:23:00 GMT
Thanks for your response,
Will you please let me know something about my first post regarding Client
Acknowledgement Vs Transactions ? -->
"I have a requirement where I am confused between transactions and Explicit
acknowledgement. The requirement is:
When a consumer receives a message it do some processing with the message
before acknowledging the message. And while processing the message it could
get some exception and consumer might crash in the middle of processing the
message and when it comes up again, it should get the message. So since the
message is already consumed but could not be processed completely, i want to
get that message again.

So here what should I use, transactions or explicit acknowledgement ? how to
get this redelivery of messages ?

In addition to that I also want to know behavior of transactions on both
producer and consumer side.
Like client acknowledgement is only for consumer. Is transactions for both?
if yes, how differently it works for producer and consumer ?
