Subject Re: Active MQ 5.11.1 MQTT Message is automatically sent to subscriber when it is connected
Date Thu, 18 Jun 2015 03:12:50 GMT
Thanks William-2.

1. Yes, AMQ does not support that.  So I tried to create a pre-defined a
Durable Topic Subscriber from Webconsole to receive all the message. These
message is in pending in state.

When my actual Subscriber is connected, all the above pending message are
delivered to my Subscriber.

This solution is working with Active MQ 5.10, 5.11. 

But the ActiveMQ 5.10, 5.11 is having a bugs. This bug is not related to my
solution. I mean that I run the ActiveMQ immediately after unzip the folder
without any setting. The bugs is still happen.

That is:

"The broker is  always sent the messages which already sent to the
subscriber before to the 
subscriber when it is connected."

Does anyone meet the same trouble with me?

Thanks so many!
