Subject Re: Fail to reconnect to AMQ queues after restarting the broker
Date Mon, 02 Feb 2009 10:21:54 GMT
Hi,

if you put just one broker URL inside the failover transport URI, like

failover:(tcp://localhost:61616)

the client will try to reconnect to that broker in case that connection
dies.

Regards
