Subject Re: Fail to reconnect to AMQ queues after restarting the broker
Date Mon, 02 Feb 2009 10:14:34 GMT

Hi, the failover transport lets you load balance clients over a number of
brokers.
However, i have one broker and i don't need any more brokers.
I want the client to be able to reconnect to the same broker once it is up
again.
How can i do that?

Thanks, Michal
