Thank you for the reply, Gert. I have done that and am able to add additional application specific properties to the JMS message just fine. I am asking in specific regard to the JMS Header properties, such as JMSPriority, JMSExpiration (TimeToLive), etc. I know the <jms:provider/> endpoint allows you set these statically (the same for all messages that pass through), but I am looking to make them dynamic based on a section of the message being sent. Looking at the code, it looks like these are set in the JMSTemplate in the endpoint's start() method (based on data members in the endpoint, which I assume are set from the xbean, for instance) and then are never changed again. I've followed the method calls all the way down to the JMS send in the Spring Framework and these JMS Header properties are definitely never retrieved from the message properties (the final send call includes a message producer, the priority, timetolive, and one other header prop I cannot recall). It seems to me that the JMS header properties should be message specific as opposed to endpoint specific, but perhaps I am not understanding the JMS API correctly.
