JMS API failover
Hi,
I'm building a client with JMS API and want to achieve automatic
reconnection mechanism, that is when the connection to the broker is lost
the client should reconnect automatically, resubscribe queues, etc.
I've added failover=roundrobin to my connection URL and that seems to work
even though there is only one broker in the brokerlist (it iterates over
that single broker). On the other hand, the application code is not informed
at all of the disconnection/reconnection events, because it's all done under
the hood by the API.
Is it possible some way to get some automatic reconnection mechanism, and at
the same time know when the connection is broken (to inform the end user of
the temporary disfunction of the system), and when the the connection is
re-established (to inform the end user the system has come back to
operation)?
Thanks in advance for any advice.
Regards
Marco

Hi Phil,
I understand I have to call the QPID concrete implementation of the JMS
Connection, rather than the Connection interface itself which does not offer
this functionality.
To recap, I need to be handle the following connection events:
1) First connection is established successfully. I can't see a specific
listener method called in this case. Should I assume the connection is
established after I have called the Connection's start()?
2) Connection broken. I think I am notified on ConnectionListener's
preFailover() method when this occurs, right?
3) Connection re-established. Should be the ConnectionListener's
failoverComplete() method as you suggested, right?
Thanks
Marco

Hi Marco,
Try this:
((AMQConnection)yourJmsConnection).setConnectionListener(
new org.apache.qpid.jms.ConnectionListener() {
...
public void failoverComplete() {
...
}
...
}
