Apache Camel can do redelivery using the camel error handling. This is not related to JTA though. So the more solid way is to configure redelivery in the JMS broker.
ActiveMQ can configure redelivery on the ConnectionFactory and centrally on the broker. For more information, see: http://activemq.apache.org/message-redelivery-and-dlq-handling.html. The user can set the number of redeliveries, the backoff behaviour and the dead letter queue where messages end up if all fails.
