Subject [jira] Commented: (AMQ-895) JMS to JMS Bridge never reconnects under remote broker restarts.

Alf E. Helseth commented on AMQ-895:
------------------------------------

Thanks Manuel!

I now got rid of the wrapper, the <constructor-arg> stuff worked out just fine!

So to the ClassCastException, it really comes from the ActiveMQ program itself, the moment
I try to send a message into the queue on the JCAPS broker queue that is defined to be inboundQueueName,
and the bridge tries to fetch it into AMQ.
The other way around messages (sendt to the outboundQueueName on AMQ) are bridged correctly
over to JCAPS.

The consumer/provider programs are using javax.jms.TextMessage as contents. 
I have also tried to use the JMXConsole connected to AMQ for sending simple test messages.

You says that the bridge should automatically convert incoming messages to native AMQ - seems
to me that that's where the error occurs ?

Alf (with steep learning curve regarding ActiveMQ...)

> I'm using ActiveMQ (4.0.1) JMS to JMS Bridge functionality to connect to a  SunMQ JMS
Broker (3.6 SP3  (Build 02-A)). I'm using two queues, an input and an output one, with the
following configuration:
>     <jmsBridgeConnectors>
>       <jmsQueueConnector outboundQueueConnectionFactory="#REMOTE">
>       <outboundQueueBridges>
>         <outboundQueueBridge outboundQueueName="SUNRECV"/>
>       </outboundQueueBridges>
>       <inboundQueueBridges>
>         <inboundQueueBridge inboundQueueName="SUNSEND"/>
>       </inboundQueueBridges>
>       </jmsQueueConnector>
>     </jmsBridgeConnectors>
> The system works really well until the SunMQ broker needed to be restarted. This is what
I found:
> 1.-ActiveMQ is not aware of the remote broker shutdown. I waited for a while, but no
log on ActiveMQ indicates knowledge about the new situation.
> 2.-When I send a message to the output queue SUNRECV, ActiveMQ complains that the producer
is closed:
> [ERROR][2006/08/25.09:47:12.039][ActiveMQ Session Task]failed to forward message: ActiveMQTextMessage

Cannot perform operation, producer is closed.)
>  After this, it is automatically queueing messages without sending them, showing the
log:
> [DEBUG][2006/08/25.09:47:42.721][RMI TCP Connection(4)-10.95.89.20]No subscriptions registered,
will not dispatch message at this time.
>  Even if SunMQ is started again, ActiveMQ is not detecting the new situation, and continues
queueing messages sent to SUNRECV.
> Please, make me know if more information is needed to understand the situation.
