Hello! I have a spring message-driven pojo (via SimpleMessageListener) that is receiving messages out of order ('cancel' before 'new') occasionally.
There is only one message producer, but it's using JmsTemplate, which is configured with an activemq PooledConnectionFactory. The example at http://www.activemq.org/site/total-ordering.html focuses on two producers, but I am working on the theory that a single producer may create out of order messages given connection pooling. Is this correct? Is there any way to configure the topic for total ordering via the API? Would it be better to stop using JmsTemplate and provide the single producer a dedicated connection? Thanks in advance from an activemq/jms newbie... Steven Marcus
