Subject Bridging not working reliable
Date Fri, 19 Feb 2010 22:27:10 GMT

H!

I'm trying to use a Bridge to Oracle JMS. 

I have a embeded Broker with a local persistant Queue and a bridge to
Oracle. If all systems are fine, no problems.

-------------
BrokerService broker = new BrokerService();

JmsQueueConnector jmsQueueConnector = new JmsQueueConnector();
QueueConnection createQueueConnection = new
QueueConnectionWrap(queueConnectionFactory.createQueueConnection());

createQueueConnection.start();

jmsQueueConnector.setOutboundQueueConnection(createQueueConnection);

OutboundQueueBridge outboundQueueBridge = new
OutboundQueueBridge("DEV_MSGQ");
outboundQueueBridge.setLocalQueueName("SUBJECT");
jmsQueueConnector.setOutboundQueueBridges(new OutboundQueueBridge[] {
outboundQueueBridge });

broker.setJmsBridgeConnectors(new JmsConnector[] { jmsQueueConnector });
broker.setBrokerName("fred");
broker.setPersistent(true);
broker.start();
---------

The problems coming when the Oracle Server goes down:

The Sender of the Queue does not try to reconnect.

I wraped the QueueConnection/QueueSession/Sender and now a Exception in
Sender.sendMessage() gets a new QueueSession, a new Queue and a new Sender
so I can reconnect.

If my reconnection its not successful an I throw a Exception in
Sender.sendMessage, the message is removed from the Queue anyway and its
lost:

The Message ID:NBK092-1401-1266616208578-2:1:1:20:1 is lost now. The Bridge
should roll this transaction  back.


What can I do?

Thanks

Juergen
