Subject Re: How to forward a full message received in Java by onMessage() into another queue?
Date Fri, 20 Aug 2010 10:07:18 GMT
you need to think of each jms message as a fire and forget entity,
immutable once sent. The properties whose name begin with "JMS" are
for use by the JMS implementation so they will be set by the sender
JMS implementation code to what ever is needed by the implementation.

An application is in control of the payload and any non standard
properties, it is an applications responsibility to replicate these
attributes from message to message (camel does this sort of thing for
you automatically with some sensible defaults). The application cannot
expect invariance of the standard JMS* or JMSX* properties.
