> Hi,
> I am implementing ActiveMQ Middleware using point to point .
> I am facing this issue from last few days
> There are multiple message posted to my activemq and one i start activemq my session starts reading messages.I am using individual message acknowledgement.
> i.e  qConnection.createQueueSession(false, ActiveMQSession.INDIVIDUAL_ACKNOWLEDGE);
> Once i receive message in my message listener i am sending message to child thread and processing message there and processing is completed i am sending acknowledgement.
> But problem here is if any exception comes in middle of my message i want to reattempt for that specific message.
> I have tryed session.recover here but its recovering all messages on that session which is wrong
> Please look into my message consumer and listener
>            Consumer class outline
> public  QueueSession session = null;
>  
> public QueueConnection qConnection = null;
> 	ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);           
>  	qConnection = connectionFactory.createQueueConnection();
> 	session = qConnection.createQueueSession(false, ActiveMQSession.INDIVIDUAL_ACKNOWLEDGE);
>         QueueReceiver _receiver =
>                     session.createReceiver(getTransactionQueue(session));
>         _receiver.setMessageListener(getMessageListener());
>  	public void onMessage(Message message)  {
> 		//starting chaild thread etc  
> 		if(doprocess()){
> 			session.acknowledge();
> 		} else {
>   			//want to roll back particlur message
> 		}  
>       }
> Please help me to resolve this issue
> Thanks & Regards
