How to configure failover for jmsBridgeConnector

[bbuzzard <Bi...@bnsflogistics.com>]

I'm a newbie to ActiveMQ and I need a little help.  I followed an example
showing how to set up a bridge between OpenJMS and ActiveMQ.  The bridge
seems to work perfectly, but if I stop then restart OpenJMS while leaving
ActiveMQ running.  Once I restart OpenJMS I try sending a message from it to
ActiveMQ, but ActiveMQ doesn't receive it until I stop and restart ActiveMQ. 

After a little more reading it looks like failover should fix this problem,
but I don't know how to configure it.  I'm attaching the config file that I
use for ActiveMQ bridging.  Would someone please show me the correct way to
configure failover?

note that the failover transport of part of the activemq client, it will not
work with OpenJMS. There is currently no facility to retry jms connections
to a foreign provider by the ActiveMQ JMS bridge.
Could you open a jira[1] enhancement, describing your use case, to track
this. It is something we should implement. Essentially some configurable
retry logic in the event that JMS exception ocurrs on the foreign end of a
bridge.

You specify the failover protocol by enclosing the existing URL with
"failover:(<existing_url>)"

So you'll need to change the URL that you are connecting with to for example
look like:
failover:(tcp://localhost:1234)

Beware though that if you are using activeMQ 5.2 or before the failover
protocol does not have a timeout setting and any connecting threads will
block until a connection is re-established.
