Subject Dynamic Activemq failover
Date Wed, 03 Mar 2010 21:16:11 GMT

I have an issue about using the activemq failover. I think you can help me.

My system uses camel (using cxf, mail, tcp and other components) and uses an
activemq queue to send out messages, using a variable number of routes "TO"
destinations. Recently, We've found the need to use activemq failover when
sending a message, and give a message to user if the communication has a

In my system all camel routes can be dynamically added/updated, using system
received XML messages that specifies the route name, transport type, address
and an unique id. For each added route, an activemq queue is created with
the sufix "_<routeId>" in its name. Then a camel route is created to send
messages from that queue to the route address specified in the message. Thus
messages can be sent by email, web services, or whatever.

Message contains message "Hello", route id=1, transport=file, address=:/dir
Would create a route from("activemq:queue:out_1".to("file:/dir")
Then messages to route id=1 would be put in the above queue and then in the

The questions are:

1) How can I declare the failover in this situation?

1) How can I add the failover to the dynamically added queue, using the
received route 'TO' address contained in the message? Is it possible to
configure dynamically, using a RoutBuilder?

I need to declare a failover that tries to send the message to the "TO"
address contained in the message, trying for 1 second.

2) Is it possible to dynamically declare the failover, and if the route is
updated, update the failover configuration?

Thank you,
Ricardo Melo
