Subject Re: Fail to reconnect to AMQ queues after restarting the broker
Date Mon, 02 Feb 2009 08:31:19 GMT
Hi,

take a look at failover transport

http://activemq.apache.org/failover-transport-reference.html

you should use this transport on the client side to enable successful
reconnection.

Cheers
